This paper examines oil and gas accumulations on the Musi Platform in the western part of P.T. Exspan Sumateras Extension Block. Exploration activities in this area started in 1939, when BPM drilled the Kikim-1 well and discovered gas in the Baturaja limestone, which developed into the main producing reservoir on the Musi Platform (De Coster, 1974). A total of 30 wildcat wells were drilled over the next 60 years, 20 of which discovered hydrocarbons. Only two of the discoveries were oil, the remainder found gas. These accumulations occur in five different types of carbonate build-up in the Baturaja Formation.Interest in this old trend rekindled in 1997 following Exspans Soka- 1 wildcat, which found substantial gas in a Baturaja reefal limestone. Soka-1 was drilled on the flank of the Bungur High, a basement uplift.
