Talos Energy Inc. today provided an update on the Zama appraisal program in Block 7, located in the offshore portion of Mexico's prolific Sureste Basin. Talos is the operator of Block 7 in a consortium (the Consortium) with its partners Sierra Oil & Gas, a Wintershall DEA company, and Premier Oil.
The Zama-3 appraisal well is the third and final appraisal penetration drilled by the Consortium to better define the resource potential of the Zama discovery. The Zama-2 and Zama-2 ST1 appraisal penetrations, both drilled in the first half of 2019, generated results that met or exceeded the Consortium's expectations. The Zama-3 well was drilled approximately 1.5 mi (2.4 km) south of the original Zama-1 location with the goals of testing the southern extent of the reservoir and capturing additional reservoir description data.
The Consortium is continuing to evaluate the full universe of data and samples collected from its four penetrations of the Zama reservoir, including approximately 1,450 ft of whole core, fluid samples from 30 separate points in the reservoir, 180 pressure points, 25 logging runs and two extended flow tests, with the goal of integrating this data with internal models and sharing it with external auditors to produce an updated contingent recoverable resource report by year end. However, based on the preliminary information collected to date, Talos expects the updated value will fall in the upper half of the previously provided pre-appraisal guidance range of 400-800 MMboe.
The results specific to the Zama-3 well were as follows:
The Consortium is simultaneously advancing both its front-end engineering and design (FEED) work streams as well as unitization discussions with Petróleos Mexicanos (Pemex), with the aim of making a Final Investment Decision (FID) on the project in 2020, pending required government approvals.
