Manora joint venture partners approved the three-well exploration drilling program plus a contingent appraisal sidetrack well at the end of October 2019. The exploration wells, in order of drilling are Inthanin-1, Yothaka East-1, and Krissana-1.

Mubadala is the operator of the G1/48 license and Tap Oil is its partner with a 30% working interest.

Tap said on Thursday that mobilization operations had started on November 17, 2019, with the Ensco 115 jack-up drilling rig reaching the Inthanin well location on November 18, 2019. The well location is 3.7 km south-southwest of the Manora platform.

The Inthanin-1 well spudded on November 20 and is scheduled to take approximately 11 days to complete the drilling.

The Inthanin prospect trap is a three-way dip closure with the added possibility of a larger combination trap at the 500 sands level. The primary objective of drilling the Inthanin-1 well is to explore for hydrocarbons in the 400, 500 and 600 series sands levels, all of which produce in the Manora East fault block 1.6 km to the north-northeast. The target reservoirs are fluvial at the 400 and 500 level and lacustrine at the 600 level.

Following the drilling of the Inthanin-1 well, the rig will be moved on to drill the Yothaka East-1 and Krissana-1 wells. A contingent sidetrack, into the Yothaka structure will be dependent upon the results of the Yothaka East-1 and Krissana-1 exploration wells.

It is also worth reminding that Mubadala completed a three-well development drilling program at its Manora field last August. This campaign was also drilled using the Ensco 115 jack-up rig.
