Two gas discoveries found offshore Sarawak

TWO gas discoveries have been made offshore Sarawak in Block SK316 at the Kasawari and NC8SW fields.

These discoveries have enhanced the prospect of gas play in the State.

The former is one of the largest non-associated gas fields in Malaysia.

A statement from Petronas said preliminary assessments carried out early this month indicate that gas-in-place for the Kasawari field is over five trillion standard cubic feet with an estimated recoverable hydrocarbon resource of just over three trillion standard cubic feet.

“The well-test conducted produced 29 million standard cubic feet per day of gas,” said Petronas.

The NC8SW-1 well, which is located about 17km south of Kasawari, was drilled last September to a total depth of 3,853 metres.

Gas was found in a 440-metre column in similar carbonate reservoirs and the recoverable resource for the NC8SW field is estimated at over 450 billion standard cubic feet of gas.

Let’s not forget that last month, Petronas and Shell Malaysia signed the world’s biggest offshore enhanced oil recovery (EOR) project in Sarawak and Sabah.

The project involved using EOR or other related technologies to develop nine oilfields in the Baram Delta and four in the North Sabah development area.

This is to increase the average recovery factor in the Baram Delta and North Sabah fields from some 36 per cent to 50 per cent, with over 750 million barrels of oil expected to be recovered.

If realised, the technology will also be able to extend the field’s life to beyond 2040.

So it looks like the oil and gas industry in Sarawak is secure for the next few decades. Great stuff.

Petronas Discovers Gas Offshore Sarawak

KUALA LUMPUR, Feb 13 (Bernama) — Petronas has made two gas discoveries in the Kasawari and NC8SW fields in Block SK316 offshore Sarawak via exploration wells Kasawari-1 and NC8SW-1.

In a statement, the national oil and gas company said the Kasawari-1 well was drilled in November 2011, and gas was found in the carbonate reservoirs.

The well, drilled to a total depth of 3,196 metres, penetrated about 1,000 metres of gas column — the longest drilled section of gas column in Malaysia, it said.

“Preliminary assessments carried out in early February 2012 indicate that gas-in-place for the Kasawari field is over five trillion standard cubic feet (TSCF) with estimated recoverable hydrocarbon resource of just over three TSCF, making it one of the largest non-associated gas fields in Malaysia.

“The well-test conducted produced 29 million standard cubic feet per day (mmscfd) of gas,” Petronas said.

The NC8SW-1 well, about 17km south of Kasawari, was drilled in September 2011 to a total depth of 3,853 metres, and gas was found in a 440-metre column in similar carbonate reservoirs, it said, adding the recoverable resource for the NC8SW field is estimated at more than 450 billion standard cubic feet of gas.

Kasawari-1 and NC8SW-1 are the latest wells drilled in Block SK316 and the gas discoveries, a direct result of Petronas’ strategy to intensify domestic exploration, have enhanced the prospect of the gas play in Sarawak.

For 2012, Petronas and its production sharing contractors are planning to drill 30 exploration wells to further enhance the prospect of Malaysia’s basins.
