Exploration Success in the Sarawak Block, Greater Sarawak Basin

In April 2018 Sapura Energy confirmed that the Pepulut 1 vertical wildcat, the second of a two-well drilling programme located within its 4,354.6 km2 Greater Sarawak Basin SK-408 block was plugged and abandoned as a gas discovery after having been drilled in 84m of water to a TD of 2,640m within its objective Cycle V carbonate section. The unofficial potential resource estimate for the discovery had been placed at 350–400 Bcfg. The well was spudded on 17 December 2017.

The first well of the drilling programme, Jarak 1, is understood to have been plugged and abandoned as a non-commercial gas well in late January 2018, having been drilled to a TD of 1,929m, also within its objective Cycle V carbonate section. 

Gas Discovery Wells

The two-well programme completes Sapura’s ten-well commitment within the block, eight of which are gas discoveries, namely;

  • Teja 1
  • Gorek 1
  • Larak 1
  • Bakong 1
  • Jerun 1
  • Jeremin 1

These wells are close to existing infrastructure supplying gas to one of the world’s largest liquefied natural gas facilities at Bintulu, Sarawak. Equity in SK-408 is split between operator Sapura with a 40% interest in the block, with partners Shell and Petronas Carigali each holding 30%.

The South China Sea Enigma

The South China Sea, a marginal sea between Asia (the largest continent) and the Pacific (the largest ocean) covers an area of 3.5 million square kilometres and is surrounded by sedimentary basins, some of which have produced petroleum for decades. The oceanic and the stretched continental crusts underlying the South China Sea have experienced a complex tectonic history in Cenozoic times, which geologists are only beginning to unravel.
