Mubadala Petroleum and Tap Oil’s first of three-wells has come up dry in the Gulf of Thailand.

The Inthanin-1 exploration well drilled in the G1/48 concession Manora Oil Field was spudded on 20 November 2019 and reached a total depth of 2528m on 24 November 2019.

“Target objectives in the well were intersected within 15m of pre-drill prognosed depths however no significant shows were encountered while drilling and evaluation of log data indicates no zones of interest in the well,” Tap Oil said.

While evaluation of the well results and reasons for the lack of hydrocarbons is ongoing, it is notable that the prognosed sandstone reservoir targets in the deeper “500” and “600” sand series were very poorly developed.

The drilling of the Inthanin-1 well was completed ahead of schedule and below budget cost, Tap said.

Following completion of plug and abandon operations, the Ensco 115 jackup drilling rig will move to drill the Yothaka East-1 well. The Yothaka East-1 surface location is 6.0 km SE of the Manora Platform. The Yothaka East-1 well is expected to spud on Friday 29 November 2019.

This well will test an independent structure to the Inthanin feature in an expected separate sand fairway.

Yothaka East-1 will be followed by the Krissana-1 exploration well.

Mubadala Petroleum is the operator in the production license in the Northern Gulf of Thailand with Tap Oil holding a 30 per cent interest.
