Significant gas discovery in Indonesia

Abu Dhabi’s Mubadala Energy announced another substantial gas discovery from the Tangkulo-1 Exploration well, drilled in South Andaman, about 65 km offshore North Sumatra, Indonesia.

The discovery marks the second deep water well operated by the company. Tangkulo-1 was drilled to a depth of 3,400 meters in 1,200 meters water depth, just a few months after the major discovery at the Layaran-1 well, also in South Andaman.

The Tangkulo-1 well encountered 80 meters of gas column in a good quality Oligocene sandstone reservoir confirmed through an extensive data gathering campaign that includes obtaining a full core of 72 meters, wireline logging, sidewall core, pressure and fluid sampling. Utilizing a new Drill Stem Test (DST) design, the well successfully flowed 47 mmscf/d of excellent gas quality and 1,300 barrels of condensate. Although testing was constrained by testing facilities, the estimated well capacity is 80-100mmscf/d and over 2,000 barrels of condensate. 

“When added to our recent success at Layaran-1, this game-changing discovery promises to transform Indonesia’s and Southeast Asia’s energy landscape and demonstrates that South Andaman is one of the world’s most exciting energy plays,” said Mansoor Mohammed Al Hamed, CEO, Mubadala Energy.
