EIA Updates Eagle Ford Maps

January 29, 2015 Elizabeth Alford

The U.S. Energy Information Administration (EIA) has released new maps that include updated information for Eagle Ford derived from producing wells from January 2000- June 2014 based on The maps are categorized in the following geological parameters.

Initial GOR

This map shows the detailed production in relation to the natural gas to oil ratio (GOR) of the play.

Play Footprint

This map shows the four boundaries of the Eagle Ford Play

North - This boundary is determined by the temperatures at which oil is generated from rock and stops at 3650 feet in Frio County and counties east, and in Maverick and Zavala counties from 650 to 2900 feet.
South - This boundary follows the Sligo Reef Margin.
Northeast - This boundary where the lower Eagle Ford thins and grades into more silica-rich units of the Pepper Shale of the East Texas Basin
West - This boundary is marked by the border with Mexico

Elevation Contours

This structure map characterizes the depth of the play and represents the minimum drilling depth to reach the top of the Eagle Ford formation.

“The Eagle Ford formation is divided into upper and lower units, and the top of the lower unit is considered the best proxy for the source rock; however, due to a lack of density and distribution of the depth to the top of the lower Eagle Ford formation, this map represents an approximation of the elevation of the top of the upper Eagle Ford unit.”

Thickness Contours

This map provide a rough estimate of the thickness of the play, which is used to estimate resource volumes, such as oil- or gas-in-place estimates, in combination with other information such as porosity, pressure, and geologic history.

Eagle Ford Rig Count Decreases by Three to 232

January 26, 2015 Elizabeth Alford

The Eagle Ford Shale rig count decreased by three to 232 rigs running across our coverage area by the end of last week.

In recent Eagle Ford news, the U.S Geological Society registered close to a dozen quakes in the region ranging in intensity from a 2.6-3.7 on the richter scale within a 36 hour period. Earthquakes in Texas have been on the rise in recent years, causing many to make a connection between increased seismic activity and the fracking throughout the state.

Eagle Ford Rig Count Decreases to 235

The Eagle Ford rig count decreased by 13 this week ending at 235, adding to the sharp decline seen in the region as we lost 26 active rigs in the last four weeks.

WTI crude prices have decreased by ~$9.59 since December 19th, trading at $55.99/bbl on Monday morning. As oil prices continue to drop, reports of deeper budget cuts and layoffs are now daily news.

Eagle Ford and Bakken are both experiencing a decrease in rig count, but other regions are also seeing a decline. The U.S. rig count decreased to 1,676 rigs running by the end of last week with a total of 310 rigs targeting natural gas (down 28 from December) and 1,366 targeting oil in the U.S. (down 170 since December).

What is the Rig Count?

The Bakken Shale Rig Count is an index of the total number of oil & gas drilling rigs running across Montana and North Dakota. The rigs referred to in this article are for ALL drilling reported by Baker Hughes and not solely wells targeting the Bakken formation. All land rigs and onshore rig data shown here are based upon industry estimates provided by the Baker Hughes Rig Count.

Urban Drilling Ordinance Hearing

January 21, 2015 Elizabeth Alford

Are you a mineral or royalty owner in the College Station area? If so, you’ll want to mark your calendar for an important city council meeting tomorrow and consider signing up to voice your opinions.

The College Station City Council will be considering an Urban Drilling Ordinance on January 22nd and the public is invited to attend and give comments. Speakers may present a 3 minute presentation.

For many royalty owners, restrictive ordinances such as this one prevent responsible oil and gas development and infringe on private property rights. Most concerning is the 1,500-foot setback requirement contained in the ordinance. Concerned owners assert that this requirement is unnecessary intervention because research confirms that 600-foot setbacks are enough to protect public health. If this is true, then this ordinance would amount to a de facto ban, if passed. These owners are calling for the community to base decisions about oil and natural gas activity on sound science.

College Station City Council Meeting

City Hall - Council Chambers 1101 Texas Avenue S., College Station, Texas

Wastewater Disposal to Continue in Texas

January 19, 2015 Elizabeth Alford

Eagle Ford Disposal Well Map — Eagle Ford Injection Wells

Landowner rights in Eagle Ford took another hit last week when Judge Russell Wilson denied a request to stop the further development of an underground wastewater disposal facility.

Sable Environmental, LLC obtained a permit from the Texas Railroad Commission (TRC) to store 20,000-25,000 barrels of wastewater underground in Karnes County, and the decision immediately drew fire from local landowners who are fearful that the water will contaminate their property. After banding together, they filed a lawsuit seeking an injunction to stop the company from proceeding. Judge Wilson denied the request on January 14th, choosing instead to wait on a decision in a similar case before the Texas Supreme Court that will set a precedent for future cases of this nature.

“As the Eagle Ford Shale continues its development, I think that we are going to see more and more instances in which the rights of the property owners are going to collide with oil and gas industry’s operations. While property owners should consider the needs of the industry in their decision making, the industry needs to respect the rights that landowners have in their property when conducting their operations. Finding that balance is going to be crucial for the long-term success of the Eagle Ford Shale.”

— Attorney, Clinton Butler

Wasterwater disposal has become a hot topic as hydraulic fracturing has increased over the last few years. After drilling, the wastewater is cleaned and then pumped deep into injection wells. The potential risks of this practice are still unknown but are commonly connected to increased earthquakes, water contamination and danger to the ecosystem.
