IRESS 2020:

ESCI 557 (Section 3)- Special topics in Earth Sciences

Unconventionals: from subsurface carbon to reservoir characterization 

Fridays 2-4 PM, KWGL 100

2 credits

Instructors: Ken Abdulah, Jonathan Ajo-Franklin, Dorothy Ballentine, Melodie French, Cin-Ty Lee, Daniel Minisini, John Sneider, Mark Torres

The ability to tap unconventional reservoirs, such as low permeability source rocks, has revolutionized the energy landscape in the United States, with far-reaching economic and geopolitical implications. At the same time, this foray into unconventionals has opened up a plethora of basic scientific questions related to the origin, evolution and migration of these hydrocarbons. This course will bring together an interdisciplinary group of academics and industry leaders to tackle a number of key outstanding questions. How do tectonics, basin evolution, climate, volcanism, ocean circulation and carbon and nutrient cycling on the regional and global scale control the formation of source rocks? How are the processes of sedimentary deposition manifested in terms of lithological, mechanical, and chemical heterogeneity on lengthscales from microns to meters? How can basic geologic and physical principles, in conjunction with various geophysical methods, be used to predict and extrapolate to a basin scale?   What are the basic physics involved in natural and induced migration of fluids, and can we gain insight from analog systems elsewhere? We will also discuss how these concepts translate into the completion of wells and their useful lifetimes, how unconventionals have changed the economics and geopolitics of energy, and finally, what the environmental and social costs have been. There will be a three day field trip out to Eagle Ford formation in west Texas to bring many of these concepts together. The interdisciplinary nature of this course will lead to new understanding in basic and applied hydrocarbon research.

Student presentations

Synthesis (play elements, exploration)

Guidelines for talks: The seminar will be over 2 hours and consist of an introductory talk followed by a more topical talk. Each talk should be planned for no more than 40 minutes so as to provide ample time for discussion. All talks should be given at a level in which a broad audience can understand. The goal is to generate cross disciplinary discussions. The first talk must introduce basic and general concepts. The second talk can focus more on case studies.

All talks should attempt to first highlight what we currently know about the discipline exposed and how we know that. Talks, including the introductory parts, should also highlight what are some of the newest developments in the field, their implications, and open questions that need further research.

Student expectations: Students taking the course for credit are expected to read papers and participate in discussions each week. Students are also expected to organize into groups of 3 to 4 to tackle outstanding research problems. Groups should be interdisciplinary. Groups are expected to present their work at the end of the semester.
