About the Eagle Ford Shale
The Eagle Ford Shale is a big deal in the Oil & Gas industry and is expected to become even more prevalent in years to come. Shale is a sedimentary rock rich in organic material called kerogen. As this organic material decays hydrocarbons, such as oil and gas are released. This shale is the source for other oil and gas zones inside South Texas, such as the Austin Chalk formation, which usually lies above the Eagle Ford, as well as the huge oilfields in East Arizona.
Approximately 65 to 145 million years ago during the Cretaceous geologic period, it was formed. It lies at a depth of between 2500 feet at the edge of the hill country to over 15,000 feet deep in southern LaSalle, McMullen, Live Oak, Bee, DeWitt and LaVaca counties. Over forty miles wide and four hundred miles long, spanning an area from near Mexico to East Texas, is the area of oil and gas activity. Pressures are higher and gas volumes greater at the deeper or more mature end of the formation. In some areas, the “play” is over 330 feet thick. The shale was not recognized as an economically viable oil and gas reservoir until recently. Oil and gas can now be extracted easily because of a technology called horizontal drilling, which allows for a hole to be drilled across shales like the Eagle Ford for up to a mile or more, and because of advances in hydraulic fracturing, which uses high pressure liquid to bust apart the shale.
Making it very brittle and therefore able to be fractured easily with a frac job, the shale is high in carbonate content. More than other shale plays, porosity and permeability are greater in the Eagle Ford shale. With an average clay content of eleven percent, core samples of the shale contain as much as 70% calcite. In wells all the way from Maverick County near the Mexican border to Dewitt county farther east the shale is producing impressive amounts of both oil and natural gas. The current epicenter of activity in terms of horizontal drilling is along the Stuart City Reef and Sligo shelf trend from Maverick, McMullen, LaSalle, Live Oak and a handful of other counties farther east. Areas in the farther north, where the Austin Chalk has produced oil, companies are finding oil in the shale as well. The two formations are highly correlated, with the Eagle Ford shale being one of the major “source rocks” for oil that is found in the Austin Chalk formation.
Since a well that was drilled in the Eagle Ford Shale would quickly deplete down to nothing, it was not thought of as any kind of resource that could be produced. There was not enough porosity or natural permeability to consent to for much oil or natural gas from the couple hundred feet of out in the open shale to dribble out. That’s why the Eagle Ford shale is without question, the next big thing in the Oil & Gas industry.
About Selling Mineral Rights
We’re here to help you make the best choice when selling your mineral rights or royalty interest. Choosing the right company to work with is invaluable, and you should take your time to understand how these companies work, and how they will value your mineral rights.
When you’re deciding whether or not to sell your mineral rights, consider the simple question:
“Will I be disappointed if my mineral rights do not produce significant income for me and my family?”
If your answer is yes, then you should take the time and consider selling all or part of your mineral rights or royalty interest. If there answer is no, then likely have significant cash deposits, a well diversified portfolio and no immediate or potential cash needs.
Selling your oil and natural gas royalties are similar to selling mineral rights. However, there is one key concept to remember. You CAN sell your royalty interest WITHOUT selling your mineral rights. In this case, you will be selling your royalty interest from a particular lease. If production on that lease ends, and the HBP (Held By Production) timeline ends, then you will be free to sign a new oil and gas lease unencumbered by your previous royalty sale agreement.
