Kosmos Energy found oil with its deepwater Tiberius exploration well in the Wilcox trend in the Gulf of Mexico, the company reported Oct. 11.

The infrastructure-led exploration well, testing a four-way structural trap, encountered about 250 ft of net oil pay in the primary Wilcox target. The well was drilled to 25,800 ft true vertical depth. Wireline logging is complete, and Kosmos said casing was being run to the target depth so the well could be used as a future oil producer.

Kosmos plans to perform rock and fluid analysis to confirm the production potential of the reservoir and will work with partners on subsea development options. The discovery is about 6 miles southeast of the Occidental Petroleum-operated Lucius spar production facility, enabling a short tie-back in the event of a development.

The Tiberius well is in 7,500 ft water depth in Keathley Canyon Block 964.

During an August conference call with investors, Kosmos CEO Andrew Inglis said the Tiberius well had spud in July and was expected to wrap up drilling in September. It was targeting an estimated gross resource of around 135 MMboe, he said.

Kosmos operates the well with 33.34% interest on behalf of partners Occidental and Equinor ASA, each with 33.33% interest.
