KUALA LUMPUR (Feb 13): Petroliam Nasional Bhd had discovered two gas fields offshore Sarawak with a total gas-in-place of 3.45 trillion standard cubic feet.
The national oil corporation said on Monday the two discoveries were in the Kasawari and NC8SW fields in Block SK316.
Petronas said the Kasawari-1 well was drilled in November 2011 and found gas 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.
“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,” it said.
Petronas said the NC8SW-1 well was 17km south of Kasawari and was drilled in September 2011 to a total depth of 3,853 metres and found gas in a 440-metre column in similar carbonate reservoirs.
“The recoverable resource for the NC8SW field is estimated at more than 450 billion standard cubic feet of gas,” it said.
It said the NC8SW-1 well also discovered potential oil play which required further assessment to determine its commercial viability.
