Premier Oil has announced a gas discovery on the Singa Laut-1 well in Tuna production sharing contract (Premier Oil operator, 65%) offshore Indonesia.
The well penetrated 177ft of net gas-bearing reservoir quality sands within the targeted Oligocene sequence. Gas gradients have been measured and gas samples recovered. The gas appears to be of similar quality to the liquids rich gas found in the adjacent Kuda Laut well.
The Singa Laut-1 well will now be plugged and abandoned as a successful exploration well. Appraisal drilling to further assess the combined Singa Laut and Kuda Laut oil and gas resources is targeted for 2015.
Ratu Gajah, offshore Indonesia, Natuna Sea Block A:
The Ratu Gajah-1 well penetrated the targeted deep Lama section with gas shows. "Whilst sandstone quality is low, a drill stem test (DST) is being performed to demonstrate movable hydrocarbons," Premier says. "Integration of this well result into our basin modelling has allowed us to identify significant thicker sands in this play at the basin margin. After the DST results, the immediate follow up for the play will be the appraisal of the Anoa Deep discovery in early 2015, and the high grading of other prospects in the Lama play which have a gross prospective resource in excess of 1.5Tcf.
