The Block 3/05 joint venture offshore Angola has changed its drilling order. The Borr Grid jackup will go straight to the Impala-2 development well, then return to the Pacassa SW sidetrack once Impala-2 is complete.
The partners say the new sequence makes better use of the rig while preparations and equipment mobilization for the sidetrack are finished.
Impala-2 timeline
Impala-2 is set to spud in mid-October. Drilling and completion are expected to take about 80 days, with completion targeted for the end of December. First oil is expected in January 2027 at an initial gross rate of about 4,000 barrels of oil per day (bopd).
Reservoir pressure and productivity data from the Impala-1 intervention, which restarted production from that well, went into the final well plan. Afentra expects an incremental resource upgrade for the field after Impala-2.
Pacassa SW
Pacassa SW encountered 136 meters of net oil pay. It will be sidetracked because operational problems are restricting access to the wellbore. First oil from the well is now expected in the first quarter of 2027, after connection to existing Pacassa production infrastructure.
Afentra said remapping of the discovery is continuing. It expects the work to confirm incremental resources of up to about 70 million barrels of oil.
