The Farnsworth Field Unit (FWU), a mature oilfield in the northeastern Texas panhandle, is currently undergoing CO2-enhanced oil recovery (EOR) with the intent of long-term storage. Multidisciplinary and multiscale data from the Pennsylvanian Morrow Formation were analyzed to improve the characterization of the Morrow B injection zone. A high quality time-lapse Vertical Seismic Profile (VSP) was acquired to monitor the fluid and stress changes caused by the withdrawal and injection of fluids (McMillan, 2021). All data were synthesized into an integrated earth model that formed the basis for geophysical and engineering simulations.
Tom Bratton is a consultant to the oil and gas industry specializing in geoscience applications for engineering operations. After retiring from a 36-year career with Schlumberger, he was a Visiting Professor and Research Associate in the Petroleum Engineering Department at Colorado School of Mines (CSM). While at CSM, he enrolled as a graduate student and earned his PhD in Geophysics. Before starting his consulting business, Tom was a scientific advisor to Schlumberger’s senior management, specializing in petrophysics, geophysics, and geomechanics with a broad base of experience in drilling, completion, and reservoir engineering. Tom is a full member of the Society of Petroleum Engineers (SPE), Society of Petrophysicists and Well Log Analysts (SPWLA), Society of Exploration Geophysicists (SEG), European Association of Geoscientists and Engineers (EAGE), and the American Rock Mechanics Association (ARMA).
