An open-hole drill stem test (DST) was performed on the weekend over an 18 metre interval from 5,134m to 5,152m measured depth.

Santos said a flow rate of 7,488 barrels of oil (1,190 kilolitres) per day was recorded through a 1/2 inch (12.7 millimetre) surface choke accompanied by 2.21 million cubic feet (62.6 thousand cubic metres) per day of gas during a 5 1/2 hour flow period.

The flow rate was constrained by the throughput capacity of the surface production test facilities.

Following completion of the flow test the well was shut-in for measurement of pressure build-up, after which the testing equipment will be removed from the hole. Jeruk-2 will then be deepened in order to ascertain the full extent of the hydrocarbon column. Logs will be run when the well has reached total depth.

“These preliminary results from Jeruk-2 are very encouraging and we look forward to the final evaluation of the well,” said Santos’ managing director, Mr. John Ellice-Flint.

Jeruk-2 was drilled to follow up the Jeruk-1 well, which finished drilling in early April 2004 about 1.6 kilometres west of Jeruk-2. The well is in the Sampang PSC in water depth of 44 metres and it is located approximately 42 kilometres from the Indonesian city of Surabaya.

Interests in the field are Santos Group (operator) 50% and PT Medco Sampang 50%
