Petronas Sarawak gas find sets company depth mark

Malaysia’s Petronas has made two sizable gas discoveries offshore Sarawak, one of which is the company’s deepest vertical well and its first completed high-pressure high-temperature well.

Petronas Carigali drilled Tukau Timur Deep-1 to a record 4,830 m on the SK307 block and discovered 12 gas-bearing reservoirs with a combined 183 m net thickness.

A preliminary assessment indicates gas in place in Tukau Timur field to be about 2.1 tscf, the company said. Subsequent work will start to estimate the range of recoverable volumes.

Petronas Carigali is operator of SK307 with 50% interest, and Sarawak Shell Bhd. has 50%.

Meanwhile, Petronas discovered Kuang North field on the SK316 block with an estimated 2.3 tscf of gas in place in the older carbonate section, opening a new exploratory play type with what the company calls “substantial hydrocarbon potential.”

Petronas found Kuang North field with the Kuang North-1 and 2 exploratory wells. Kuang North-2 went to 3,223 m and penetrated 636 m of gas column.

The SK316 block also contains the recent Kasawari and NC8 gas field discoveries, Petronas noted.
