North Gas Discovery

The Kuang North field, located in Block SK316 was drilled by PETRONAS in October 2012 via two exploration wells, Kuang North-1 and Kuang North-2. The Kuang North-2 well, which was drilled to a total depth of 3,223 metres, penetrated 636 metres of gas column.

Preliminary assessments indicated that gas-in-place for the Kuang North field is about 2.3 trillion standard cubic feet (tscf) net hydrocarbon. Other notable recent discoveries in Block SK316 are the Kasawari and NC8 gas fields.

Unlike other previous carbonate gas discoveries, the gas at Kuang North was found in the older carbonate section, opening up a new exploration play-type with substantial hydrocarbon potential in the older carbonate reservoirs offshore Sarawak.

Tukau Timur Deep Gas Discovery

Tukau Timur Deep-1 is the first completed high pressure high temperature (HPHT) well in Sarawak and is also the deepest vertical well to be drilled by PETRONAS. The well was drilled to a depth of 4,830 metres and discovered 12 gas bearing reservoirs with total net gas sand of 183 metres.

Preliminary assessments indicate the total gas-in-place for Tukau Timur Field to be about 2.1 tscf. Subsequent work will commence to estimate the range of recoverable resource volumes.

Tukau Timur Deep-1 is located in Block SK307 which is operated by PETRONAS Carigali (50%) with Sarawak Shell Berhad (50%) as partners. The well was spudded in May 2012 and was completed in November 2012.
