Speaker: Trey Cortez, Senior Geologist for Burnett Oil Company
Subject: Geology of the 6666 Ranch
Abstract: The iconic 6666 ranch is not only home to acclaimed quarter horses and genetically-superior angus cattle but also houses world class oil and gas reservoirs. The main section of the ranch covers approximately 1/3 of King County and has produced over 100 MMBBLs from the Strawn, Cisco, Bunger, Canyon, and Tannehill formations. Burnett Oil Co. Inc., acquired 266 sq. miles of high-effort multi-component seismic in 2017 and have since been investigating the complex geology and petroleum systems found on the ranch. Detailed processing, mapping and inversion has pinpointed mechanisms driving the production of existing fields and a number of previously undiscovered geologic features. This presentation will provide a broad overview of the geologic setting and how modern well data has been integrated into ongoing exploration.
Bio: Trey Cortez is the Senior Geologist for Burnett Oil Co., Inc. in Fort Worth, Texas. He began his oil and gas career in 2010 while finishing his graduate work on the chemostratigraphic framework of the Wolfcamp formation in the heart of the Midland basin. His career roles have included reservoir characterization for Encana (now Ovintiv) focusing on fractured carbonates and operations/development of the highly fractured lower cretaceous carbonate section of east Texas for a small private operator named ENXP. There he also gained significant experience integrating seismic inversion with core and log-based geological inputs to develop several stochastic and deterministic inversions and related reservoir models. His current role at Burnett Oil Co., Inc. affords him the opportunity to combine previous reservoir, operations, and development experience within a small technical group responsible for all aspects of many operated and non-operated assets. Throughout his career he has served roles as Treasurer, Vice President and President of the Fort Worth Geological Society, SWS AAPG Social Event Chair 2021, SWS AAPG K-12 Education Chair, and currently serve as a Board Member and Secretary of the Oil Information Library of Fort Worth as well as the 2025 SWS AAPG Convention Chair.
