Internal Research Seminar Resources

USGC.ou.edu — 23 Oct 2014

We have formalized an internal research seminar series where researchers and students choose or are assigned a topic
and are asked to make a presentation covering the current state-of-the-art and to open discussions for research
implications and advancement. These topics range widely in scope and are targeted to encourage interactions and
discussions; most are related to ongoing research activities. Also part of the assignment is to provide up to five seminal
papers related to the topic. These papers may be examples of good or bad science, background information, new experimental
techniques, geological frameworks, etc.

We are making both the presenters’ slides and recommended papers available to our consortium members. We hope you find
useful information in this new feature as well as a limited library of current topical publications. Your feedback on this
feature is always welcomed.

Devon Energy Corp., University of Oklahoma develop rock lab

Devon Energy Corp. and the University of Oklahoma have developed new methods to study shale formations that could house significant reserves of oil and natural gas.

NewsOK.com — 17 June 2011

Devon Energy Corp. and the University of Oklahoma have been breaking new ground over the past several years to improve their understanding of the rocks that are integral to the oil and natural gas industry's current success.

Devon has invested almost $20 million in research and facility development at OU's Mewbourne School of Petroleum and Geological Engineering over the past six or seven years, helping create a unique laboratory for studying shale and other rocks with technology borrowed from other industries.

Shale Holds Huge Potential for Researchers at Universities

JPT/JPT Online — June 2011

photo

A simple question, “Can you tell us about shale?” has spawned growing research programs at universities around the globe.

In less than five years, industry-supported university research has played a key role in defining the structure and elements in shale. The work in a group of laboratories at the University of Oklahoma (OU) in Norman, Oklahoma, is an example of the competitive drive to understand these challenging rocks. Read full article.

FEI offers solution for unconventional natural gas extraction

R&D Magazine — February 24, 2011

photo

Microscope manufacturer FEI Company recently announced a novel solution for analyzing the production characteristics and potential of unconventional gas reservoirs. The Helios NanoLab DualBeam system images kerogen, porosity and microstructures in three dimensions (3D) with nanometer-scale resolution. The data are essential to determining the production potential of the reservoir, optimizing extraction procedures and designing simulators of the nanoscale pore structure.

The University of Oklahoma, in collaboration with Devon Energy, is an early adopter of this novel solution. The Helios system captures images and develops a 3D microstructural model of the pore structure, including the subvolumes of kerogen and its connectivity. The data produced by the Helios are central to a series of recent publications (1, Sondergeld et al. 2010; 2, Sondergeld and Rai 2010; and 3, Curtis et al. 2010) that cast these unconventional reservoirs in a new, more complex light.Read full article.

FEI Unveils Novel Solution for Natural Gas Extraction in Unconventional Reservoirs

GLOBE NEWSWIRE — February 14, 2011

photo

"Huge reserves of natural gas are known to exist in unconventional gas reservoirs, but it is difficult to produce this gas because it is trapped in poorly connected networks of pores with dimensions as small as a few nanometers," said Dr. Paul Scagnetti, vice president and general manager, Natural Resources Division, FEI. "The ability to understand the structure of these networks allows geologists to make more accurate predictions of producible gas and optimize its extraction."Read full article.
