Petronas Carigali Sdn Bhd (PCSB), a subsidiary of Petronas, has made a gas discovery in Block SK411 in the shallow waters of Balingian Province about 170 km northwest off the coast of Sarawak, Malaysia.
The Hadrah-1 well was drilled to a total depth of 1,850 m in November 2021 and encountered gas within a 200-m thick sequence of high-quality sandstone and carbonate reservoirs.
The discovery supports prospectivity in the underexplored Cycle I, II & III plays within the Balingian province, said Emeliana Rice-Oxley, vice-president of exploration, upstream.
“The excellent quality of reservoirs encountered augurs the remaining potential in the surrounding areas, with PCSB well positioned to pursue the untapped similar plays in Blocks SK411 and SK306,” Rice-Oxley said.
PCSB is operator with 90% participating interest. E&P Malaysia Venture Sdn Bhd. holds the remaining 10%.
Hadrah-1 is PETRONAS’ third gas discovery in this province in 2021, after Sirung-1 and Kulintang-1 in March and May, respectively. In 2019, oil and gas were also discovered within the same play at the D18 field.
