Mubadala Energy, headquartered in Abu Dhabi and operating in the South Andaman Gross Split PSC, has announced another significant gas discovery in Indonesia. The Tangkulo-1 Exploration well, located approximately 65 kilometers offshore North Sumatra, drilled to a depth of 3,400 meters in 1,200 meters of water depth, has encountered an 80-meter gas column in a high-quality Oligocene sandstone reservoir. This marks the company’s second deep-water well in the region, following the Layaran-1 discovery a few months prior.
The successful exploration of Tangkulo-1, confirmed through extensive data collection including core sampling, wireline logging, and fluid analysis, demonstrated a gas flow rate of 47 mmscf/d and 1,300 barrels of condensate per day. Despite testing limitations, the estimated well capacity exceeds 80-100mmscf/d and over 2,000 barrels of condensate. Mansoor Mohammed Al Hamed, CEO of Mubadala Energy, expressed confidence in the transformative potential of this discovery for Indonesia’s and Southeast Asia’s energy landscape, emphasizing the region’s promising prospects in energy exploration.
With an 80% working interest in South Andaman, Mubadala Energy holds the largest acreage in the area. The Tangkulo-1 discovery aligns with the company’s gas-focused strategy and contributes to the development narrative of the region, unlocking additional gas resources and supporting the government’s development objectives. This discovery, coupled with Layaran-1, offers substantial contingent volume and sets the stage for further exploration and appraisal efforts, driving Mubadala Energy’s growth trajectory in the region.
