    Title:     Accounting for Stress Sensitive Formations in the Farnsworth Field Unit 

    Authors: Tom Bratton*, Tom Bratton LLC; Lianjie Huang, Los Alamos National Laboratory; William Ampomah, New Mexico Institute of Mining and Technology


    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).

    On 4 June, 1921, J. Clarence Karcher and his colleagues performed the first seismic reflection experiment in Belle Isle, Oklahoma City, which successfully demonstrated the ability to image subsurface structures from seismic waves. In July and August of 1921, additional experiments were conducted at Vines Branch in the Arbuckle Mountains to correlate subsurface reflections with surface geology. In the past century seismic reflection has been widely used in the energy industry to explore and exploit the world’s petroleum reservoirs and more recently, geothermal and other resources as well. Furthermore, imaging the Earth through seismic has led to major contributions and revolutions in understanding the Earth’s history and structure, aided tectonic reconstructions, and serves societal needs related to geohazards and engineering. Processing and analysis of seismic data have also been and continue to be important drivers in the advancement of technology and computing.

    This workshop will feature an historic documentary on the early events and pioneers, showcase recent developments and advances in seismic acquisition, processing and interpretation, and moreover suggest innovative pathways into the future of seismic. Because of the wide applications of the seismic method, the event will invite participations from industry, academia, and government agencies.

    The three-day event will include technical presentations at the Hamm Institute for American Energy and Oklahoma State University, 300 NE 9th St., Oklahoma City, Oklahoma.  A field trip on 14 April will visit the site(s) where the first seismic reflection experiments were conducted in the Belle Isle and the Arbuckle Mountains, along with some key geologic outcrops.

    We welcome abstracts for the Seismic Reflection Centennial: Mapping the Earth Beneath Our Feet workshop.

    Oral and poster presentations will address the following topics:

    Past, present, and future of seismic reflection

    • History and development of reflection seismic
    • State-of-the art and outlook (case studies, industry, academia, current projects, and activities of universities and companies)
    • Impacts of the reflection method on technology and society
    • Fundamental scientific advances through seismic reflection methods
    • Recent developments in seismic acquisition, processing, and interpretation
    • Future of seismic reflection

    More info to follow!  We will likely be organizing transportation from Tulsa to attend the event, especially the Day 3 Field Trip excursion.
