The Jeruk-3 appraisal well is being drilled in the Sampang PSC, offshore Indonesia, approximately 1.8 km west of Jeruk-1 and 40 km south east of Surabaya.
As reported by Santos on 18 May 2006, the Jeruk-3 appraisal well has been flow tested over the open hole interval 4939 m MD to 4978 m MD (4663 m TVDSS to 4696 m TVDSS). This test was curtailed after several hours, prior to the flow and pressure being stabilized, due to a loss of control line pressure.
Following repairs, the well was subsequently re-tested over the same interval. The main flow test was conducted over a 48 hour period, and the well flowed oil at a stabilized rate of approximately 2750 bbl/day with a GoR of approximately 320 scf/bbl through a 16/64” choke, at a well head pressure of approximately 4500 psi.
Flow rates were constrained by surface facility limitations.
The forward plan is to drill ahead to locate the oil/ water contact and to continue the evaluation of the reservoir interval.
