LONDONOphir Energy plc has completed a drillstem test (DST) on the Fortuna-2 well in block R offshore Equatorial Guinea.

After drilling and coring the well, a DST was conducted to prove the deliverability of the Fortuna gas field. The DST achieved a sustained flow rate of 60 MMcf/d (1.7 MMcm/d) with a drawdown of less than 20 psi at the reservoir. This rate was surface equipment constrained. Based on the expected operating conditions of the FLNG facility, the well is estimated to have been able to deliver a production rate of 180 MMcf/d (5 MMcm/d) via the 5-in. drill pipe that was used for the DST.

The flow rate, at minimal drawdown, is suggests that the number of development wells required for the Fortuna reservoir will be reduced from the seven initially assumed in scoping work, thereby improving development economics. During pre-FEED, this result will be evaluated, in conjunction with the core, to create reservoir models that will then help determine the final number of development wells.

The next milestones for the block R FLNG development will be the agreement of gas fiscal terms and the selection of the consortium to build, own, and operate the mid-stream project. Both of these are anticipated by year’s end. The award of the upstream and midstream FEED contracts is planned in early 2015. FID is expected in 2016, and first gas in 2019.

Ophir holds 80% of block R, andGEPetrol holds 20%.
