Swedish E&P Tethys Oil announced Dec. 12 it has suspended its Kunooz-1 exploration well in Block 58, onshore Sultanate of Oman.

The decision comes after flow testing failed to confirm the presence of commercially-viable hydrocarbons, Tethys said in a press release. The company conducted open hole testing of the Ara/Birba and Buah formations.

During drilling, oil shows were present in the Amin formation and testing confirmed the existence of “high-quality” reservoir rock, Tethys said. The reservoir is able to “maintain high productivity with water flows to surface,” Tethys said. Additionally, source rock and a petroleum system were found in the region.

Tethys Oil said the test gave a better understanding of the prospectivity of the play. The company will now focus on further evaluation efforts of the collected data.

Kunooz-1 is Tethys first exploration well on Block 58, drilled to a total depth of approximately 3,900 m. Drilling operations, which commenced Aug. 19, are expected to be ongoing for about 45 days, according to the company’s site.

Tethys also divested its entire direct and indirect holding of interests in Lithuania, the company said in a separate Dec. 13 release.

As a result of the sale, Tethys Oil has no remaining interests in Lithuania. No financial effect is expected from the divestment.
