Frio County Eagle Ford Shale Info

Eagle Ford Shale Blog Editor — Tue, 01 May 2012 17:13:07 +0000

As you can see from the map below, the Eagle Ford Shale in Frio county lies outside of the “volatile oil” and “wet gas and condensate” windows of the play. These two areas are where the most intense new oil and gas drilling activity is occurring in the Eagle Ford Shale formation. The Eagle Ford Shale in Frio county has a lower GOR ratio or “gas to oil ratio,” meaning that there is less natural gas pressure in the formation to help force valuable liquids such as crude oil and condensate out into the wellbore. Thus Frio county shale wells tend to have lower IP or initial production rates and lower EUR rates (estimated ultimate recovery,) than oil and gas wells to the south and east in the over pressured part of the Eagle Ford Shale. That being said however, Frio County has and will continue be an important area in terms of oil and gas drilling. A number of formations are prospective for hydrocarbons in Frio county, such as the Eagle Ford Shale, Austin Chalk and Pearsall Shale formations. Since the depth of the Eagle Ford shale in Frio County ranges from just over 4000′ in northern Frio County to around 8000′ in the southern end of the county, drilling costs are lower than in the southern and eastern parts of the play. Companies active in Frio county oil and gas exploration include Cabot Oil and Gas, El Paso E&P, Texas American Resources Co., Cheyenne Petroleum, EF Energy, Blackbrush Oil and Gas, Goodrich Petroleum, Maverick Energy Group, Dan A Hughes Co., Chesapeake Operating and Hess Corporation.

Oilfield Activity Around Pearsall Texas

Anyone who has recently traveled between the town of Pearsall (the county seat of Frio county,) and Cotulla on IH-35, may have noticed that there are dozens of new oil and gas businesses in that area. Pearsall had a population of around 7000 residents according to the 2001 census, however judging from the number of new businesses, the traffic on area roads and from all the new construction, the population of Frio county has most likely climbed in the past couple of years. The Frio county government is currently dealing with increased wear and tear on area roads. So far no per – well fee has been imposed on oil and gas companies to offset road and bridge wear in Frio County, but one may be considered if the amount of drilling activity picks up.

Many of the oil wells (green dots,) seen on the map above are old Austin Chalk wells. Most of the ones that you see on this map were drilled in the late 1980s to 1990s and have been plugged. These wells featured a very short lateral (horizontal wellbore) or two, but generally nothing in terms of the lateral length that is possible today. The technology required to horizontally drill and hydraulically fracture the Austin chalk and Eagle Ford Shale formations simply did not exist back then in the same form that it does today. After completion, many of these wells came in as so-called “barn burners,” since their large gas flares burned for days. Some of the first Austin Chalk wells in Frio county produced hundreds of barrels of oil per day. Some oil company insiders referred to these high IP (initial production,) wells as “doctor wells” because the high IP results were so good at helping lure new investors such as physicians. Sadly for both the investors and the oil companies, Frio county Austin Chalk wells did not last more than a few weeks or months before depleting to a barrel or two of oil per day. During this flurry of oil and gas production in Frio County, a number of oil and gas gathering lines and transmission pipelines were constructed to transport Austin Chalk production to market. Pipelines built for Austin Chalk production, such as the Harvest Pipeline Company’s Pearsall Mainline, are now being used to transport Eagle Ford Shale production eastward to refineries such as Valero’s in Three Rivers.

What’s in store for Frio county in terms of Eagle Ford Shale drilling? Right now oil and gas companies such as Chesapeake Energy and EOG Resources are scrambling to drill high IP and high EUR wells in the volatile oil and wet gas windows of the EFS, (to keep share prices high and fund new drilling activity with high production wells,) in addition to hold leases about to expire. Oil and gas E&P companies will balance the need to drill Eagle Ford Shale wells in Frio County with their overall objectives in the greater Eagle Ford shale play. Some leases are held by production from older Austin Chalk and other oil and gas wells, therefore there is no rush to drill on those leases. Frio county is about 1,134 square miles in size, or approximately 725,760 acres. Potentially productive Eagle Ford shale lies beneath more than half of this area, so Frio county will most likely be in the game for many years to come, as hundreds more oil and gas wells are drilled over the coming decades. As natural gas prices rise, interest in drilling the Pearsall shale will return. The Pearsall shale, a large formation containing primarily dry natural gas, also lies under much of Frio County in addition to the Eagle Ford shale.

Zavala County Eagle Ford Shale Info

Eagle Ford Shale Blog Editor — Thu, 26 Apr 2012 22:07:25 +0000

Oil and gas drilling activity in the Zavala county portion of the Eagle Ford Shale play has diminished in recent months with the primary focus of activity being farther to the south in counties such as Dimmit and LaSalle. Those counties have a much larger footprint in the “wet gas and condensate” and “volatile oil windows” of the play. Most of the county of Zavala lies in the “heavy oil” portion of the Eagle Ford Shale, which is part of the Maverick Basin. Here the GOR or “gas to oil ratio” is lower, meaning there is less natural gas in the formation to help release oil from the tight pore structure of the rock. Currently this part of the shale is not being as sought after, as higher producing wells are being made in the over – pressured sections of the play to the south and east, where the GOR ratio is higher. Last year Petrohawk Energy (which was acquired by BHP Billiton,) considered the Red Hawk field in Zavala county one of the company’s “crown jewels”. Red Hawk has all but been abandoned as far as drilling activity is concerned. This began when Petrohawk Energy began to run out of operating capital. No doubt there will be renewed interest in the heavy oil portion of the Eagle Ford shale in Zavala and Maverick from the major players, but for now, if the exploration company has “volatile oil” or “wet gas” acreage to drill, that’s where their rigs are going to go. So far the Texas Railroad Commission has issued approximately 40 permits for horizontal Eagle Ford Shale wells in Zavala County in 2012 (as of April 26.) The primary oil and gas exploration companies who are drilling in Zavala include Chesapeake Operating, CML Exploration, Eagleford Energy Inc, Hess Corporation, Matador Production Company, Petrohawk Operating and Dan A Hughes Co.

For many years Crystal City was known as the “Spinach Capital Of The World.” “Wintergarden” vegetable farms around the area still produce much of the nation’s supply of Popeye’s favorite vegetable. Crystal City has not completely taken on the feel of an “oilfield town” just yet, as has Carrizo Springs, located in Dimmit County just a few miles to the south. There is however a noticeable increase in the amount of traffic on area roads and a number of new businesses such as RV parks in southern Zavala County. One such new park is the Caza Ranch RV park, which can be seen below, located on the Big Wells Highway, just south of Crystal City.

Below is a map from the Texas Railroad Commission showing some of the drilling activity in Zavala County, south of Crystal City.

What’s in store for Zavala County in terms of Eagle Ford Shale drilling? Although Zavala county Eagle Ford shale wells typically have lower EUR (Estimated Ultimate Recovery) and lower IP (Initial Production) rates, they are cheaper to drill, since the formation lies at around 4000′. There is no doubt that the major oil and gas companies will return to the county in earnest at some point. In Zavala county there exists favorable geology for “stacked pay” opportunities, with the Escondido, Olmos, San Miguel, Anacacho, Austin Chalk, Eagle Ford shale, Buda and Georgetown formations prospective for hydrocarbons. Currently some companies with leases in Zavala County may let the primary term of the lease expire and pay landowners an additional bonus payment to hold the acreage for a couple more years until they can shift rigs back in this direction. Some of the Eagle Ford Shale acreage in Zavala County is held by production from older oil and gas wells. We may see more drilling activity in Zavala County in the latter part of this year as oil and gas companies drill to hold acreage on larger parcels where they may find it too costly to pay extra lease bonus payments to hold the land for a couple more years.

Bee County Eagle Ford Shale Info

Eagle Ford Shale Blog Editor — Thu, 26 Apr 2012 17:42:44 +0000

Although one of the hottest areas of the Eagle Ford shale play, the “wet gas and condensate window” only reaches a few miles into Bee county, economically this is a very important area in terms of providing vital resources and services to the oil and gas industry. After many years of experiencing minor oil and gas booms and busts, Beeville Texas is quickly becoming a major oilfield hub for the region. Numerous oilfield service companies have opened new satellite offices in and around Beeville, Pawnee and Pettus, TX. According to the Texas Railroad Commission, there have been less than a dozen permits issued for new Eagle Ford Shale wells in Bee County so far this year, (as of April 22, 2012.) Oil and gas companies with operations in Bee county Texas include Talisman Energy USA, Petrohawk Operating, Pioneer Natural Resources and Burlington Resources Oil and Gas. In addition to oil and gas well permits, there have been permits issued to Complete Vacuum and Rental Inc, Mego Resources LLC and Fields Exploration Inc for saltwater disposal wells in Bee County. As you can see in the map below, the depth of the Eagle Ford shale in Bee County ranges from more than 11,000′ near the Karnes and Live Oak county lines, to over 14,000′ in the lower half of the county.

Below is a photo of a well just inside the Bee county line, east of Three Rivers, Texas.

Overall the Eagle Ford shale oil and gas discovery is helping to boost the economy of Bee County, yet there are major issues that must be dealt with. One of these issues is that of wear and tear on roads and bridges in county. Recently the Bee County Commissioner’s Court approved a $9,500 fee to be levied against the largest oil and gas companies for each new Eagle Ford Shale well drilled. The purpose of this new fee is to help offset the county’s maintenance expenses for repairing roads and bridges. Although this new fee may help pay for some of the road damage in Bee County being caused by Eagle Ford Shale drilling, it will not pay for all of it. The new road and bridge fee does not address the issue of companies using state and county roads to move equipment across Bee, to wells being drilled in other counties. Below is a photo of trucks hauling frac sand near the Bee County line. Road such as State Highway 72 are beginning to show major signs of wear and tear, as potholes appear faster than TXDOT workers can patch them. With the huge Texas budget deficit, TXDOT has been slow in responding to the critical road situation in South Texas. There has so far been very little in the way of new funds for local Highway Department districts to use for road repair and expansion.

What’s in store for Bee County in terms of the Eagle Ford Shale? As long as oil prices stay high we will see more drilling occurring in the “wet gas and condensate” portion of the county. Most of the Eagle Ford shale in Bee County is situated in the “dry gas window” of the play. Other than to keep leases from expiring on large ranches, there has been very little activity in this portion of the Eagle Ford Shale. This will most likely change as natural gas prices eventually do rise again. Vast amounts of natural gas lie beneath Bee, as well as other counties with a footprint in the “dry gas window.”

Dimmit County Eagle Ford Shale Info

Eagle Ford Shale Blog Editor — Thu, 26 Apr 2012 15:08:42 +0000

The western part of the Eagle Ford shale play, in counties such as Dimmit and Zavala, has not received as much media attention as the eastern side. Despite this however, Dimmit county is the currently epicenter of a frenzy of oil and gas drilling activity. Carrizo Springs is the county seat and the largest city in Dimmit County, Texas. Carrizo Springs is quickly becoming a regional oilfield hub, as oil and gas service companies open up satellite offices there. There are scores of newly opened oilfield businesses in Carrizo Springs, along with heavy traffic on area roads. A veritable flood of oil and gas royalty income is beginning to pour into the hands of some fortunate owners of large ranches, such as the Briscoe family, as well as benefiting smaller landholders. Oil and gas companies drilling in Dimmit County include Anadarko E&P, Chesapeake Operating, Newfield Exploration, Shell Western E&P, Rosetta Resources, El Paso E&P, Lewis Petro Properties and Murphy Exploration and Production. According to the Texas Railroad Commission, more than 300 new drilling permits have been issued for Dimmit County since the first of 2012. (As of April 22.) There is no sign of oil and gas drilling in Dimmit County letting up anytime soon, since the core “liquids rich” part of the Eagle Ford Shale runs right through the heart of the area. As you can see in the contour map of the Eagle Ford Shale below, the depth of the Eagle Ford runs from just over 4000′ along the Zavala County line, to over 8000′ near the Webb County line.

Below, the small town of Big Wells is living up to its name as rigs drilling Eagle Ford Shale “gushers” can be seen from almost anywhere in town. The small town was named for large Carrizo – Wilcox water wells, which were used to irrigate crops such as onions and cabbage. Now that same water is in high demand from oil companies, who use it to frac new Eagle Ford Shale wells in Dimmit county. Oilfield businesses in Dimmit County are thriving and creating many new jobs for area residents. Second Photo: The new offices of Flexpipe Systems, a new oilfield business in Big Wells Texas, which specializes in providing water line and pipe to the oil industry.

Money from the oil and gas industry that is flowing into Dimmit County may help to uplift some of the more impoverished areas of the county. Small migrant worker shacks, such as this one in Big Wells Texas, are being bulldozed down to make room for new oilfield businesses, housing and RV parks. This oil boom is not without its problems however. The government of Dimmit County is finding it hard to keep county roads maintained and keep up with the demand for classroom space for children of oilfield workers and other issues. The population of Dimmit County has long hovered around 10,000 people, yet according to some estimates that figure has nearly doubled in the past three years.

Below, a steady stream of traffic flows along State Hwy 85 between Big Wells and Carrizo Springs. On the hill in the far distance is a new oilfield business specializing in saltwater disposal from Eagle Ford Shale wells in Dimmit and Zavala counties.

There will be some reduction in the amount of oil tanker traffic across the Eagle Ford Shale play as new pipelines come online this summer. However, overall oilfield traffic will most likely continue for many years to come as thousands more wells are drilled. Dimmit County consists of 1,334 square miles, or about 853,760 acres. With some oil and gas companies experimenting with well spacing of the small as 40 acres in the Eagle Ford Shale, there will no doubt be thousands more wells drilled in Dimmit and surrounding counties.

McMullen County Eagle Ford Shale Photos

Eagle Ford Shale Blog Editor — Mon, 23 Apr 2012 14:34:12 +0000

The “oil and condensate window” or “volatile oil” area of the Eagle Ford shale, (currently the most valuable part of the play,) runs smack dab through the middle of McMullen County Texas. Some of the most intense drilling activity in McMullen County is located along and north of State Highway 72, in the core of the liquids – rich zone. Last year saw a record number of rigs running in McMullen county and 2012 is off to a good start. According to the Texas Railroad Commission, there have been more than 190 drilling permits issued in the county since January 1, 2012. (As of April 22, 2012.) Oil and gas companies drilling in McMullen County include EOG Resources, Chesapeake Energy, Swift Energy, Texon Petroleum, Aurora Resources, Petrohawk Operating Inc., Talisman Energy USA, Comstock Oil and Gas, Escondido Resources, Murphy Exploration and Production, Marathon Oil, XTO Energy and Carrizo Oil and Gas. The Eagle Ford shale lies under almost all of of the county, with the southern portion having a footprint in the “wet gas” and “dry gas” parts of the play and the central and northern part of the county lying in the “volatile oil window.” The map below shows the depth of the Eagle Ford Shale in McMullen county ranging from just over 8000 feet south of the Atascosa county line and plunging to over 14,000 near the Duval county line. Other than to hold leases on large ranches, there has not been as much activity in the “dry gas” Eagle Ford Shale play in McMullen. The Pearsall shale, Olmos sand, Edwards limestone and other productive formations also underlie much of the area. The Pearsall shale in McMullen county is located a couple thousand feet deeper than the Eagle Ford Shale and offers great potential for a large volume of natural gas production. Since natural gas prices are currently depressed, oil and gas companies are focusing on the liquids – rich portion of the Eagle Ford shale and Olmos sands. Companies such as Swift Energy and Texon Petroleum (an Australian firm,) are making some good wells in the shallower Olmos, in addition to wells in the Eagle Ford shale.

Scores of RV parks have opened up in Tilden Texas, as residents attempt to cash in on the oil boom in whatever ways they can. Several new oilfield businesses have opened on the outskirts of Tilden, including Stallion Rentals. For many years the population of McMullen County hovered at around seven hundred souls, yet an influx of oilfield workers has more than tripled the population in only a few short years. The influx of new residents and increase in oilfield activity has placed strains on everything from the school system to law enforcement, EMS and area roads. Tax revenue from oil and gas activity is helping somewhat to alleviate the burden placed on county taxpayers.

An H2S flare burns brightly behind the cactus on a new Eagle Ford shale oil well in northern McMullen County. Dark and starry skies have long ruled at night over McMullen County, however many residents have noticed how there is a constant glow in the night sky from natural gas flares and large outdoor lights placed around well sites during drilling and fracking operations. The nighttime glow from this oil boom being experienced by local residents is unlikely to fade anytime soon. McMullen County is comprised of approximately 731,520 acres, with some type of oil and gas bearing rock formation underlying almost of it. With some oil and gas exploration companies examining well spacings of as low as 40 acres, there will be thousands more oil and gas wells drilled in McMullen over the next several decades.

Gonzales County Eagle Ford Shale Photos

Eagle Ford Shale Blog Editor — Wed, 18 Apr 2012 13:05:51 +0000

Eagle Ford shale oil and gas drilling in Gonzales county remains strong into 2012. Since the first of the year, (as of April 18,) there have been approximately 140 new drilling permits issued for horizontal Eagle Ford Shale wells in Gonzales county. EOG Resources leads the way, with the most permits issued by the Texas Railroad Commission. Oil and gas companies drilling the Eagle Ford Shale in Gonzales county include EOG Resources, Marathon Oil, Penn Virginia Oil and Gas, Hunt Oil Company, Lucas Energy Incorporated, Rosetta Resources Operating Incorporated, Tidal Petroleum, Forrest oil, and Southern Bay Operating. The depth of the Eagle Ford Shale in Gonzales County ranges from around 4000 feet to over 12,000 feet. The southern edge of the county sits in the “volatile oil window.” Some very productive wells have been made south of the city of Gonzales in the Sugarkane Eagle Ford play, which is a combination of the Eagle Ford Shale and the Austin chalk. Well such as EOG Resources’ Mitchell Unit #2H, which was producing 3,090 barrels of oil and 2.9 million cubic feet of natural gas per day of initial production, are the reason that Gonzales County is a hotbed of drilling activity. Small communities such as Nixon, Smiley and Cheapside are starting to feel the effects of the oil boom, with RV parks opening up and increased traffic from oilfield vehicles. Below is a map of the Eagle Ford Shale in Gonzales county showing the depth of the formation and Gonzales county’s location in the volatile oil and heavy oil part of the play.

The photo below shows a drilling rig just southwest of the city of Gonzales, drilling a new Eagle Ford Shale well. The main street in Nixon Texas is not normally this quiet looking. This photo was taken on Easter Sunday. Oil and gas drilling activity is hot and heavy just to the south of Nixon along the Wilson, Karnes and DeWitt county lines. With some leases about to expire in Gonzales County, oil and gas companies are drilling day and night to hold acreage, as well as bring in prolific, high-volume liquids producing wells which help boost share prices and fund further drilling activity.

DeWitt County Eagle Ford Leading The Way

Eagle Ford Shale Blog Editor — Tue, 17 Apr 2012 14:54:37 +0000

As of today, some of the highest producing Eagle Ford Shale wells have been made in DeWitt County. This area of the play has some of the most favorable geology for thousand barrel – per – day plus wells, such as the Dlugosch A
Well # 1H drilled recently by Geosouthern Energy Corporation just southeast of Westhoff, and the Klaevemann Unit A Well # 1 drilled by Burlington Oil and Gas northwest of Yorktown. (Note that high IP or initial production figures of new Eagle Ford shale wells rarely hold for more than a few months before falling off.) Wells in the Sugarkane and Blackhawk fields, which span part of DeWitt, Karnes and Gonzales county, are producing high volumes of condensate and high gravity oil, as well as natural gas. Below is a photo of a new Eagle Ford Shale well in DeWitt County just northwest of Cuero.

Oil and gas exploration companies who are drilling the Eagle Ford shale in DeWitt County include Burlington Resources Oil and Gas, (a subsidiary of ConocoPhillips,) Talisman Energy USA Incorporated, EOG Resources, Marathon Oil, Geosouthern Energy Corporation, Petrohawk Operating Company, Pioneer Natural Resources, Rosetta Resources, Matador Production Company and Chesapeake Operating. Since the first of 2012, more than 125 new permits have been issued by the Texas Railroad Commission for new horizontal Eagle Ford shale wells in DeWitt county Texas. In 2011 Marathon purchased 141,000 acres from Hilcorp Resources for $3.5 billion. Some of the acreage acquired by Marathon Oil in that purchase from Hilcorp was in DeWitt county.

Below is a photo of a drilling rig in northwestern DeWitt County, near the small community of Hochiem. The prairie around Hochiem once attracted many German, Czech and Polish immigrants because of the high quality grazing and farmland it offered. Now the rich Eagle Ford Shale oil and gas play is attracting investors from across the globe. The landscape of rural DeWitt County around communities such as Gruenau, Garfield, Westhoff and Yorktown will be forever changed by this incredible oil and gas discovery.

Some oil and gas companies drilling in DeWitt County Texas are not waiting for natural gas pipelines to reach new wells before beginning production of liquids. Since natural gas prices are depressed and the price of oil and natural gas liquids is at an all-time high, some operators are using trailer mounted flare units, such as the one seen below, to flare off large volumes of natural gas. In doing so, thousands of barrels of oil and NGLs can be recovered quickly to pay for the well, boost shareholder earnings and make investor presentations look good. Such flaring of natural gas by producers in the Eagle Ford, Bakken and other shale plays, has been met with protest from some investors. Recently a letter was sent to several oil and gas companies, including Chesapeake Energy, Continental Resources, and ExxonMobil, from a group of 36 private and institutional investors representing over $500 billion in assets. (Source: Reuters News.) The letter voiced concerns over environmental issues and lost revenue from prematurely producing liquids from newly drilled shale wells before natural gas pipelines were completed. Nevertheless, the practice of flaring large volumes of natural gas so that liquids can be recovered from Eagle Ford Shale wells before pipelines are finished is not likely to end anytime soon. Natural gas prices are severely depressed due to oversupply (coming from shale discoveries such as the Eagle Ford and Marcellus shale,) and are likely to remain below $3.00 per MMBTu for many months to come. (See natural gas price forecast chart from the EIA below.)

Karnes County Eagle Ford Shale Photos

Eagle Ford Shale Blog Editor — Fri, 13 Apr 2012 21:27:14 +0000

Oil and gas drilling activity is continuing to pick up across Karnes County Texas. This is one of the core areas of the Eagle Ford Shale, since it straddles the oil and condensate window or “sweet spot” of the play. There have been around 245 permits issued since the first of the year by the Texas Railroad Commission for new horizontal Eagle Ford Shale wells in Karnes County. Oil and gas companies that are drilling wells in the Karnes County Eagle Ford shale include Pioneer Natural Resources, Talisman Energy, Marathon Oil, Plains Exploration, Paloma Resources, EOG Resources, Petrohawk, Murphy Exploration and Production, Crimson Exploration And Matador Production Company. The Eagle Ford Shale in Karnes County Texas offers some of the most productive rock in the entire play. Wells such as EOG Resource’s Deleon-Reinhard Unit #1H, which produced 2,235 barrels of oil and 1.2 million cubic feet of natural gas per day (IP or initial production,) help to make investor presentations look very good. Those who have not visited Karnes City in a few years might not recognize the place because of all the new business activity and traffic. Across Karnes County rigs drilling Eagle Ford Shale wells stand like exclamation points, proclaiming the new oil discovery.

Below is a photo of a brand-new Weatherford pumpjack on an Eagle Ford Shale well in Karnes County. Some new wells drilled in the oil and condensate window of the play will produce oil for a while on their own, before a pumpjack must be installed. Most pumpjacks in the Eagle Ford shale are powered by electric motors, which offer greater reliability and less maintenance than natural gas powered pumpjack engines. The downside is that there is not enough electricity available for new well sites, and pumping units must be placed on a portable generator, such as the one seen below. The power grid across much of the Eagle Ford Shale was installed many years ago as part of the Rural Electrification Project initiated by Pres. Lyndon Baines Johnson. It was never designed to supply millions of watts of power to oil wells, compressor stations, saltwater disposal wells, and other such energy hogging infrastructure. Some rural residents in South Texas are already reporting brownouts and power surges due to heavy demands placed on old lines. Power companies such as Medina Electric and South Texas Electric Cooperative are building literally dozens of new electric substations and laying new power lines to oil and gas wells in Karnes County, as well as across the entire Eagle Ford Shale play. The second photo shows a power substation in Karnes County under construction.

Atascosa Eagle Ford Shale Heating Up

Eagle Ford Shale Blog Editor — Fri, 13 Apr 2012 16:10:56 +0000

The drilling activity in Atascosa County has picked up considerably since the first of 2012. There are several oil and gas companies drilling the Eagle Ford shale in Atascosa county at present. They include Marathon oil, EOG Resources, Carrizo Oil and Gas Incorporated, Murphy Exploration and Production, Comstock Oil and Gas, Cabot Oil and Gas, Cinco Natural Resources Corporation, Pioneer Natural Resources, XTO Energy Incorporated, Hilcorp Energy, El Paso E&P Inc, and Chesapeake. Just about all of the major Eagle Ford Shale players are represented in Atascosa County. The number of new drilling permits issued by the Texas Railroad Commission for the Eagle Ford Shale in Atascosa County since January 1, 2011 stands at around 50. Much of the horizontal drilling activity is taking place in the lower southern half of the county. Below is a map from the Texas Railroad commission showing new oil and gas wells. (The pentagon shape indicates the surface location of the well and the colored circle at the end of the line represents the bottom hole location. Note the intense activity in the southeastern part of the county just east of Whitsett on the Karnes county and Live Oak county lines. Below is a photo of a new EOG Resources oil well in Atascosa County, just inside the Karnes County line. In the background you can see a drilling rig completing another new well.

Below is a map from the Energy Information Administration showing Atascosa County’s location in the Eagle Ford Shale play. More than half of the county is located in the oil window. Notice that the lower southeastern portion of Atascosa County lies in the “volatile oil – condensate window”, of Eagle Ford Shale. This is the area that is seeing the most intense drilling activity as oil and gas companies go after the highly valuable natural gas liquids and oil found in that part of the play. This is where the “investor presentation wells”, with initial production figures of up to two thousand barrels a month or more, are being drilled. Companies such as EOG Resources will drill as many of these wells as they possibly can before having to go drill wells to hold leases in the more oily section of the Eagle Ford Shale in Atascosa County. The depth of the top of the Eagle Ford Shale in Atascosa County ranges between 6000′ to over 10,000′.

Eagle Ford Shale Play Photos

Eagle Ford Shale Blog Editor — Mon, 09 Apr 2012 21:06:38 +0000

Here are some recent photos taken this spring of new activity in the Eagle Ford shale oil and gas play in South Texas. In this most recent collection of Eagle Ford shale photos you will find some images of new activity in Karnes, Atascosa, McMullen, LaSalle, Gonzales, DeWitt, and Live Oak counties. I recently logged about 500 miles, driving the back roads in South Texas to get a glimpse of how things are progressing in the Eagle Ford. As you cross back and forth across across the core of the “sweet spot” or liquids rich core of the Eagle Ford shale, you see a common theme. That is, oil and gas wells on a farm or ranch, and new homes with new cars in the driveway. From the looks of things, at least some of those who have received bonus money or royalty checks are spending some of it. You see farmers with new tractors, fancy new ranch gate entrances, and in towns such as Floresville, new businesses such as motels, restaurants and oilfield related businesses.

The first photo below was taken in Pleasanton, Texas, (which located just north of the major Eagle Ford shale liquids core area), shows new cars for sale on a lot next to a new motel being built. The second Eagle Ford shale photo on below was taken south of Jordanton, Texas. It shows new oilfield equipment in temporary storage before being installed on leases in Eagle Ford Shale.

Next, a drilling rig on an Eagle Ford shale well just north of Cotulla Texas, near the small community of Woodward in LaSalle county.

Below, vacuum trucks unloading produced water from Eagle Ford Shale wells at a new saltwater disposal facility north of Tilden Texas. Because of the great amount of water used to frac Eagle Ford Shale wells, there is a need for more saltwater disposal wells in the Eagle Ford Shale. Many new vacuum truck driver jobs in the Eagle Ford shale have been created as a result for this need to dispose of produced water from new wells. So competitive is the Eagle Ford Shale saltwater disposal business that you will often find facilities located across the road from each other. There is another Eagle Ford shale saltwater injection facility in Atascosa county located just across SH-16 from the one seen below.

Below is a photo taken at night, showing new natural gas treatment equipment including a separator and dehydrator unit on a new Eagle Ford well location in Karnes County. The second photo below it, shows a Union Pacific locomotive and cars loaded full of aggregate which is destined for new Well locations and roads in the Eagle Ford Shale area. The aggregate or gravel business is booming in South Texas. Some material is being sourced locally, however much of the premium aggregate material is coming from outside of South Texas.

A new well location in southern Atascosa County. This photo shows a heater treater, tank battery and a small flare burning waste gas. The second photo shows a a large new natural gas liquids gathering and treatment facility near Pleasanton Texas.
