Mubadala energy doubles down, discovers more gas offshore Indonesia

Mubadala Energy, the renowned international energy company headquartered in Abu Dhabi and the operator of the South Andaman Gross Split PSC, has unveiled another significant gas discovery from the Tangkulo-1 Exploration well, located in South Andaman, approximately 65 kilometers offshore North Sumatra, Indonesia.

This milestone marks the second deepwater well operated by the company, following the major discovery at the Layaran-1 well, also situated in South Andaman.

The Tangkulo-1 well, drilled to a depth of 3,400 meters in 1,200 meters of water depth, encountered an impressive 80 meters of gas column in a high-quality Oligocene sandstone reservoir. The confirmation of the reservoir’s quality was established through an extensive data gathering campaign, which included obtaining a full core of 72 meters, wireline logging, sidewall core, and pressure and fluid sampling.

Utilizing an innovative Drill Stem Test (DST) design, the well successfully flowed 47 mmscf/d of excellent gas quality and 1,300 barrels of condensate. Despite testing constraints due to facility limitations, the estimated well capacity is expected to be between 80-100mmscf/d and over 2,000 barrels of condensate.
