The wells in the five blocks, SK306, SK411, SK313, SK301B and SK315, stem from new and existing groups of oil fields and have low levels of contaminants, said Petronas in a statement on Monday.
The discoveries by Petronas Carigali Sdn Bhd, a wholly owned subsidiary of Petronas, come after "an intensive domestic exploration drilling campaign" that commenced in late 2022, the company added.
