Central Luconia Carbonate Exploration – An Update: After Three More SK408 Wildcats, has the Story Changed?

James Clark, Paul Owen, Sean O’Brien, Barry Dawe


Central Luconia, in shallow water Offshore Sarawak is a major gas province that has reached exploration maturity. Since the first exploration well in 1968, more than 110 wildcat wells have been drilled, discovering a total resource in excess of 60 TCF gas in-place. The overwhelming majority of this gas has been discovered within the same play: Late Miocene carbonate build-ups (Fig. 1). SapuraKencana Energy (SKE, formerly Newfield Malaysia) have been active explorers in the Central Luconia Province since 2007, to date drilling 11 operated wells and discovering a total in-place gas resource of almost 9 TCF in nine discoveries.

At SEAPEX 2015 a simple geologic model was presented to explain the successes and failures of historic exploration in Central Luconia. This model had been used to risk prospects for the phase 1 drilling campaign with great success (five discoveries from five wildcat wells). In late 2015, after integrating the results from Phase 1 and updating our geologic understanding, three further wildcat wells were drilled. Two more discoveries were made, including a significant accumulation with interpreted column height potential in excess of 900m.

In mid-2016 acquisition of the Terumbu Luconia 3D – approximately 13,000 sq km of broadband 3D seismic, was completed as part of a joint acquisition with neighbouring PSC’s (Fig. 2). Now with a modern, high quality regional 3D seismic dataset, tied to over 100 wells we are in a position to ask the question: with seven discoveries out of eight and having discovered a large gas resource – are we as good as we think....or did we just get lucky?
