Ophir Energy reports the successful Drill Stem Test (DST) on the Fortuna-2 well in Block R, Equatorial Guinea. Ophir holds 80% of Block R and GEPetrol 20%.
After successfully drilling and coring the Fortuna-2 well, a DST was conducted to prove the deliverability of the Fortuna gas field. The DST achieved a sustained flowrate of60MMscfd 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 c.180MMscfd via the 5" drill pipe that was used for the DST.
The excellent flow rate, at minimal drawdown, is a strong indication 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.
