Event Description

This is the Spring 2012 JOINT LUNCHEON

for the Dallas Geophysical Society and the Dallas Geological Society

Locating high-productivity areas of tight gas-sand reservoirs
using LF seismic surveys at Jonah and Pindale fields.

Jonah and Pindale fields in southwest Wyoming are prolific tight gas reservoirs. Jonah may have up to 8 TCF of recoverable gas, and estimates at Pinedale exceed 27 TCF. Primary production is from more than 5000 feet of discontinuous, sandstones from Upper Cretaceous Lance and Mesa Verde Formations.

A low-frequency passive seismic survey was acquired over the Jonah and Pinedale gas fields to verify whether changes in the ambient seismic wave field could discriminate the higher productivity areas. The 2D profiles of the survey crossed the field in places that show maximum contrast in well productivity. As part of the ambient wave-field characterization (AWC) processing, the anthropogenic noise generated by the operations and the infrastructure of the field was captured and analyzed.

Results of this analysis show that the AWC seismic attributes correlate well to reservoir properties like estimated ultimate recovery (EUR) and hydrocarbon pore thickness (HPT or SgPhiH) while the anthropogenic noise was not responsible for the measured AWC seismic signal anomaly. This opens the door to the use of AWC seismic surveys to extend existing tight gas-sand fields and to locating the high-productivity areas in tight gas-sand exploration plays.

Biography

Brad Birkelo is VP Geosciences at Spectraseis, where his work focuses on further developing microseismic and passive seismic techniques and integrating these data with conventional oil & gas data.

Prior to joining Spectraseis, Brad managed the Houston office of Digital Prospectors, Inc., an oil and gas consulting firm and, prior to this, worked for Phillips Petroleum in Bartlesville, Oklahoma and Odessa, Texas where he processed and interpreted seismic data on numerous exploration and development projects.

Brad received his MS in Geophysics from The University of Kansas (1987) and degrees from the University of Minnesota (BS Geology, 1982 and BS Geophysics, 1983).

Brad served as SEG Secretary-Treasurer in 2006-07 and is an active member of the SEG, AAPG, EAGE, Denver Geophysical Society, and the Geophysical Society of Houston. The SEG awarded him Life Membership in 2010.
