I

talian energy giant Eni has announced a major gas discovery off the coast of East Kalimantan, with estimated reserves of 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate.

The Energy and Mineral Resources Ministry announced on Monday the discovery at the Geliga-1 exploration well, located in the deep waters of the Ganal Block in the Kutai Basin.

“In a world where almost everyone is protecting their reserves, we are once again grateful to God for this blessing,” Energy and Mineral Resources Minister Bahlil Lahadalia said. 

“This is the result of exploration, and we must focus on the President’s order to find new oil sources.”

The Geliga well was drilled to a depth of approximately 5,100 meters in water depths of around 2,000 m. 

The Ganal Working Area is operated by Eni, which holds an 82 percent stake, with the remaining 18 percent owned by China’s Sinopec.
