Talos Reports Results of GOM Zama-2 Appraisal Well; Preps for Third

|
Talos Energy Inc. reported an update on the Zama appraisal in Block 7 offshore Mexico.
Talos is the operator of Block 7 in a consortium with its partners Sierra Oil and Gas and Premier Oil.
The Zama-2 appraisal well is the first of three appraisal penetrations drilled to better define the resource potential of the Zama discovery. The Zama-2 appraisal penetration was drilled in a down-dip location approximately 1.3 miles (2.1 kilometers) to the north of the Zama-1 discovery well.
- The Zama-2 penetration logged approximately 581 feet (177 meters) of gross TVD oil pay before reaching the oil-water contact, preliminarily estimated at 11,254 feet (3,430 meters) TVD, approximately 100 feet (30 meters), deeper than the anticipated depth of the oil-water contact based on the geophysical signature called a "flat-spot."
- Preliminary pressure data helped confirm the oil-water contact depth, complementing the traditional logging results. The pressure data also indicates that this northern section of the reservoir is connected to the Zama-1 discovery well. The Zama-2 vertical sidetrack and the Zama-3 well will provide additional information about the reservoir connectivity and consistency.
The last objective of the Zama-2 well was to test a deeper exploration prospect called Marte. Marte was designed to inexpensively test a higher risk stratigraphic trap, and although it encountered high quality sands of consistent geological age, pressures and quality, they were not hydrocarbon bearing.
