London-based Premier Oil has discovered oil at the Kuda Laut-1 well on the Tuna block offshore Indonesia.
The company encountered 183ft of net oil-bearing reservoir and 327ft of net gas-bearing reservoir, and the oil and gas samples have been recovered to surface.
Following completion of evaluation operations, the Kuda Laut-1, which is operated by Premier Oil with a 65% stake, will be side-tracked to drill the Singa Laut prospect in the adjacent fault block, with results expected in late May.
Premier Oil exploration director Andrew Lodge said: "Discovering oil at Kuda Laut is of particular significance and we now look forward to the results of Singa Laut.
"This is the first of a number of high-impact wells Premier plans to drill over the next 12 months."
Premier also said that drilling operations at the Ratu Gajah-1 exploration well in the Natuna Sea Block A PSC are working at normal pace.
The company is the operator with a 28.67% stake and results are expected in May 2014.
Premier also announced that the K-36 well on the Kadanwari block (15.79% stake) onshore Pakistan discovered a total net gas pay of 65ft and flowed at a rate of 50 million standard cubic feet per day.
On a negative note, Premier said that the Tapendar-1 exploration well offshore Mauritania (6.23% stake) and the Badhra-8 well on the Badhra block onshore Pakistan (6% stake) were both plugged and abandoned as a dry hole.
