(Asia-Pacific) - Singapore Petroleum Co. Ltd. and its partners have started drilling the Dukuh-1 exploration well in the Sampang production sharing contract in Indonesian waters.

Dukuh-1, approximately 10 km south of the Jeruk oil discovery and about 40 km south east of the city of Surabaya, was spudded on April 5, 2006.

SPC expects to take 44 days to drill the well to a depth of 3,200 m subsea to test Tertiary sandstone reservoirs within a seismically defined four-way dip closure.

SPC's Singapore Petroleum Sampang Ltd. has 36% stake in the concession, with Australian Santos (Sampang) Pty Ltd and Cue Sampang Pty Ltd 40.5% and 13.5%, respectively.

PT Petrogas Oyong Jatim, a company wholly owned by the provincial government of East Java, is managing the 10% Indonesian participation interests within the East Java provincial boundaries such as the Sampang and Madura Offshore PSCs.
