The well is in 42 meters of water and is located in the Sampang PSC, offshore East Java, Indonesia which is operated by Santos (Sampang) Pty Ltd. It is approximately 7 kilometers west of the Oyong oil & gas field in the same PSC.
A drill-stem test was conducted over the interval 1340-1365 meters. The well flowed at a rate of 18.5 million cubic feet per day through a 56/64" choke with a wellhead flowing pressure of 1071 psi. Condensate was produced at a rate of 4 to 5 barrels per million cubic feet. Like Oyong, the gas is sweet with no CO2 or H2S present.
"The results of Wortel-1 are encouraging, however further appraisal will be required to confirm the potential resource", said Santos' Managing Director, John Ellice-Flint.
Following completion of testing operations the Wortel-1 well will be plugged and abandoned as planned.
The Sedco 601 drilling rig will move to drill the Madi-1 exploration well in the neighboring Madura Offshore PSC and then, subject to partner and government approvals, return to drill the Wortel -2 appraisal well in October 2006.
The participants are Santos (Sampang) Pty Ltd as operator with 40.5%; Singapore Petroleum Sampang Ltd with 36%; Cue Sampang Pty Ltd with 13.5%; and PT Petrogas Oyong Jatim* with 10%; * subject to finalization of documentation
