Cooper Energy Limited reported Tuesday that the Bunian-3 ST2 development well in the Sukananti KSO, South Sumatra, Indonesia, is being prepared for production testing, having been cased and suspended as a future producer.
A comprehensive suite of cased hole formation evaluation logs has indicated an increase in reservoir thickness of the main target TRM3 sand and that it has been intersected 61 feet (18.5 meters) higher than in the adjacent Bunian-1 oil production well, as illustrated in Table 1 following.
In addition, interpretation suggests potential new oil and gas accumulations in other reservoirs in the Talang Akar Formation, most notably the K1 sand.
It is intended to confirm the fluid types and potential flow rates of the TRM3 and K1 sands through production testing. If the K1 sand flows hydrocarbons to surface then this will be a new pool discovery.
