Talos Energy Inc. and partners drilled the Zama-2 ST1 appraisal well 589 ft updip of the Zama-2 well and 1.4 miles north of the Zama-1 exploration well offshore Mexico on Block 7 in the Sureste basin.
Talos operates Block 7. Partners are Sierra Oil & Gas and Premier Oil PLC (OGJ Online, Dec. 4, 2018).
The Zama-2 ST1 well logged 873 ft of gross TVD pay through multiple penetrations. The well was cased and perforated totaling 248 gross ft of perforated section with varying rock properties.
Talos captured 714 ft of whole core with 98% recovery, which the company called the longest whole core acquired in a single well offshore Mexico.
Oil and natural gas flowed without stimulation in two separate tests and achieved a combined rate of 7,900 boe/d, of which 94% was oil.
The well test was completed 5 days ahead of schedule and more than 30% below budget.
Talos plans to use a combination of fixed platforms and dry trees to develop Zama in 550 ft of water. Given flow test results, peak production of 150,000–175,000 boe/d is expected.
The Zama-3 appraisal well will be drilled just south of the original Zama-1 exploration well and will assist in delineating reservoir continuity in the southern part of the field.
