Talos Energy LLC, Houston, has spudded the Zama-1 exploration well on Block 7 in the shallow-water Sureste basin offshore Mexico.
The well’s principal target is the Zama prospect with supportive direct hydrocarbon indicators in the Tertiary clastic reservoirs. The Zama structure is estimated to have a gross unrisked resource range of 100-500 million bbl. The firm is expected to take up to 90 days to drill both the Zama prospect and the secondary target, Zama Deep.
Zama-1 is the first exploration well to be drilled on acreage awarded in Mexico’s first international licensing round in 2015 (OGJ Online, July 16, 2015).
Talos Energy is operator of Block 7 with 35% interest. Partners are Sierra Oil & Gas 40% and Premier Oil PLC 25%.
