Talos completes Zama-1 well, off Mexico

Talos has completed the drilling of the Zama-1 exploration well off Mexico, in which it recently found what is believed to be a billion barrel oil discovery.

According to Premier Oil, a partner in the project, the well drilling has been completed, reaching a total depth of 4,108 metres (13,478 feet).

The logging results confirmed that the previous hole section had reached the base of the reservoir section, with an oil-down-to in the well of 3,380 metres (11,089 feet) with no subsequent penetration of an oil-water-contact. The well drilled deeper into the Zama Deep target and no additional hydrocarbons were encountered, confirming pre-drill expectations for this formation, Premier Oil said.

Premier’s estimate of the initial gross oil in-place volumes for the reservoir is, as previously announced, in excess of 1 billion barrels of oil. The gross oil bearing interval in Zama-1 is over 335 metres (1,100 feet). The well was completed on time and budget and has been suspended as a potential producer, Premier Oil said.

“Premier, together with its joint venture partners Talos Energy (Operator) and Sierra Oil & Gas is now undertaking analysis of all the data gathered from the Zama-1 well and evaluating the best way to appraise and then develop this world class discovery,” the UK-based oil company ended.
