Tap Oil on Friday shared an update on the Yothaka East-2 appraisal well drilled in the G1/48 concession Manora Production License, operated by Mubadala Petroleum, in the Northern Gulf of Thailand.

Operations on the sidetrack of the Yothaka East -2 appraisal well from the Yothaka East -1 well bore commenced on December 5, and the well reached a total measured depth of 3,881 meters on December 11, 2019.

The primary objective 600 series sands, that were interpreted to be oil bearing in Yothaka East-1 well located 1 kilometer to the south, were intersected within 4 meters of pre-drill prognosed depths and approximately 60 meters down dip of the discovery well, Yothaka-East-1.

Weak shows were encountered while drilling and logs indicated the sands while better developed, as prognosed, are water bearing in the Yothaka-East -2 location, said Tap Oil, which holds interest in the project.

Logs indicated approximately 4 meters of net (water bearing) sand in the 600 series and, pending further petrophysical data analysis, a possible oil-water contact is present in the equivalent sand to the main pay sand in Yothaka East-1.

The well is currently being plugged and abandoned.

Integrated analysis of the results of the two wells and the 3D seismic data tied into Manora is ongoing to determine the volumetric and economic significance of the 600 series reservoirs in the Yothaka East structure.
