KINA Petroleum expects successful phase 1 drilling with new seismic being acquired in Western province to increase gas and condensate resources in the Elevala Sandstone.
The Elevala-2 and Elevala-2 Side Track 1 in PRL 21 had established a field gas column of more than 50m, indicating the Elevala structure is full to spill point.
The results were on the high side of expectations, making it likely that an upgrade to existing contingent mean recoverable resources of 302 billion cubic feet of gas and 19.3 million barrels of condensate will occur when the new 105 line kilometre 2D seismic data was integrated into the existing data set.
Operator Horizon Oil had said earlier the result had also increased the likelihood the Ketu structure was also full and upgraded the prospectivity of the Tingu and the lead west of Elevala.
The Parker Rig 226 was now preparing to start phase 2 drilling with the Ketu-2 appraisal/development well.
Ketu-2 was planned as a vertical test to define the eastern down-dip limit of the gas/condensate discovery made by the Ketu-1 well in 1991.
It was expected to spud in March and should take about 45 days to reach its planned total depth of 3,800m.
Horizon’s decision to proceed with development of the Stanley oil field in PRL 4 to the north brooks well for PRL 21 as many of its development, approval, operating and capital expenditure considerations were similar to those at PRL 21.
