SEISMIC INVERSION FOR SHALE GAS/OIL IN THE AUSTIN CHALK AND EAGLE FORD SHALE IN A SUBMARINE VOLCANIC TERRAIN, MAVERICK BASIN, SOUTH TEXAS
Osareni (Chris) Ogiesoba
Bureau of Economic Geology (STARR)
Hydrocarbon exploration in the Austin Chalk began in 1916 with the discovery of hydrocarbon traps located in and around volcanic centers (serpentine plugs) encased by Austin Chalk. Owing to the occurrence of hydrocarbons around these serpentine plugs, exploration efforts were focused on identifying surface as well as subsurface locations of volcanic centers within the Austin Chalk. However, with the realization of the existence of fault-related, fractured reservoirs within the Austin Chalk in the 1980’s, fault zones became the main target of exploration—and the drilling spree started. To date, more than 2,000 horizontal wells have been drilled within the Austin Chalk.
Although some of these wells were successful, many others failed either because they did not penetrate hydrocarbon sweet spots, or hydrocarbon-source-rock distribution within and outside the Austin Chalk was unknown. In this project, seismic inversion studies was conducted by combining seismic data with wireline logs to determine sweet spots and predict resistivity distribution (using the deep-induction log) within the Austin Chalk and Eagle Ford Shale in South Texas.
Results show that >90% of productive zones are in the lower part of the Austin Chalk and are associated with Eagle Ford vertical-subvertical en echelon faults, suggesting hydrocarbon migration from the Eagle Ford Shale. Furthermore, the lower Austin Chalk and upper Eagle Ford Shale together appear to constitute a continuous (unconventional) hydrocarbon play.
In addition, local accumulations within the Austin Chalk may be related to Austin TOC-rich zones or migration from the Eagle Ford through fractures. The quality-factor attribute (Q) can serve as a tool for detecting high-water saturated zones. Although Q was not selected as one of the primary attributes for predicting resistivity, it nevertheless can serve as a good reconnaissance tool for predicting resistivity and brittle zones. Wells that have high water production do so because the water-bearing middle Austin Chalk that sits on the downthrown side of Eagle Ford regional faults constitutes a large section of the horizontal well, as evidenced by the Q attribute. Finally, based on the seismic stratigraphic positions of identified submarine volcanic mounds within the Austin Chalk, volcanic activity probably continued up middle Campanian time.

UTIG Fall Seminar Series 2026: Jason SylvanAugust, 28 2026Time: 10:30 AM - 11:30 AMLocation: UTIG Seminar Conference Room - 10601 Burnet Road, Bldg. 196/ROC 1.603 Speaker: Jason Sylvan, Department of Oceanography, Texas A&M University, professor Title: Very much alive ecosystems on dead hydrothermal vent deposits Host: Chris Lowery and Elizabeth Spiers Abstract: Active hydrothermal vent systems are a vital component of the ocean system, balancing elemental budgets, exchanging heat with the Earth’s interior, and hosting unique biological communities. While decades of study have produced robust descriptions of microbial and animal communities on and within actively venting deposits, interest in the study of their inactive counterparts is more recent. Inactive hydrothermal deposits are a potential target for deep sea mining of precious minerals, therefore it is more important than ever to document and study them to understand what ecosystem services they provide and what potentially unique biology they host to help inform conservation and management practices should mining occur. Prior and ongoing work by myself and other researchers has shown that there is a succession of microorganisms on hydrothermal deposits after vents become inactive, resulting in a microbial community with different functional potential than on actively venting deposits. This is important because it indicates that inactive vent microbial communities comprise a unique ecosystem from those on active vents or other deep sea habitats. While the identity of microorganisms on inactive vent deposits is now understood in a broad sense, rates of processes and the presence and/or identity of animal communities are still largely unconstrained. In this seminar, I will provide an introduction to inactive hydrothermal vent deposits as an ecosystem, including what microorganisms are present, and present recent developments from my lab and collaborators on their microbial ecology, the ecosystem services they are known to provide, and what little is known about animal communities on these features.

Big Rivers on Mars!September, 18 2026Time: 5:30 AM - 8:15 AMLocation: Welch Grand Hallway and 2.224 Auditorium What can ancient rivers on Mars reveal about the planet’s past and its potential for life? In this Hot Science – Cool Talks with Timothy Goudge, explore ancient rivers, catastrophic floods, and massive drainage systems on Mars, and how the planet’s lack of plate tectonics shaped its unique landscape and potential for life. By studying relic rivers and water-shaped landscapes on Mars, scientists are uncovering clues about the planet’s history and where life may once have had a chance to exist. After all, where waters flow, life often follows. |
