The Nangka-1 well was successfully drilled to a total depth of 3,758m in September.

“The sweet gas was discovered in the Middle to Late Miocene Cycle VI clastic reservoirs, further validating the hydrocarbon potential in the surrounding areas,” the company said in a statement.

PTTEP HK Offshore Ltd is the operator for Block SK417 with 80% participating interest, while Petronas Carigali Sdn Bhd holds the remaining 20%.

The block was awarded in March 2018 following the Malaysia Bid Round 2017.

Petronas senior vice-president of Malaysia petroleum management Mohamed Firouz Asnan said the success of the Nangka-1 well marks the second gas discovery within the Baram Province this year.

“The finding of contaminant-free gas in Nangka-1 reaffirms sweet gas opportunities within the area, and subsequently upgrades Baram’s clastics play.

“This second gas find further reinvigorates the Baram Province, which is part of the established Baram Delta region, signalling potential for more discoveries in the neighbouring acreages.

“The availability of existing facilities within the region will allow the petroleum arrangement contractors to monetise their discoveries quicker and cheaper through tie-back solutions,” he added.

In February this year, Petronas announced a new gas discovery in the Dokong-1 wildcat exploration well in the same block of the Baram Province.
