In its latest results statement, the company is sticking to estimated range of 400-800 MMboe issued prior to this year’s appraisal drilling on the field.
Early front-end engineering design is under way to allow for the earliest possible production date, and field unitization discussions continue as Zama extends into an adjoining block operated by Pemex.
In September, Talos secured a two-year contract term extension and regulatory approvals to allow for further exploration on additional retained acreage in block 7, which could be incremental to the Zama development.
During 3Q, Talos also participated in two wells on prospects in Mexico’s offshore block 31. Xaxamani-2EXP logged around 148 ft (45 m) of gross TVD pay, while Tolteca-1EXP well logged 123 ft (37 m) of gross TVD pay, all located in the deeper of the two shallow sands penetrated by Xaxamani-2EXP.
The Tolteca-1EXP well did not find an oil-water contact but did log hydrocarbons "full to base," exceeding Talos’ pre-drill expectations in terms of reservoir thickness and areal extent.
This has raised expectations of similar geophysical anomalies that could open up a shallow oil play in the contract area.
The Xaxamani discovery is 1 mi (1.6 km) from shore in less than 100 ft (30.5 m) of water.
