West Africa-focused energy firm Eland Oil & Gas plc announced late Monday that its joint-venture subsidiary Elcrest Exploration and Production Nigeria Ltd, together with NPDC, has completed re-entry works and boosted production at the Opuama-3 well in Nigeria.
Workover operations at the well included the perforation of two new intervals and production logging runs in both strings. The D1000 upper reservoir flowed for one hour on a 48/64" choke and produced 235 barrels of oil, which is equivalent to 5,640 barrels of dry crude per day. The D2000 reservoir flowed for six hours on a 48/64" choke and produced 1,137 barrels of oil, which equates to 4,548 barrels of dry crude per day.
The combined flow from both strings was tested for 1 hour on a 48/64" choke and produced 441 barrels of oil, which is equivalent to 10,584 barrels of dry crude per day from Opuama-3. Following the re-opening of the Forcados terminal, which Eland currently expects within a month, the company expects to recommence production from Opuama.
Eland CEO George Maxwell commented in a company statement:
"We are very pleased to announce the successful completion of the Opuama-3 re-entry and the strong results from flow testing the well. The results are beyond the high end of our previously announced expected range of 2,000-4,000 incremental gross barrels of oil produced per day. The two newly perforated reservoirs have proven to be highly productive. The initial combined flow rate from Opuama-3 well of 10,584 barrels of oil per day will move on normalized production, but will still be well in excess of our previous forecast.
“Following this significant success we now move our focus to the Gbetiokun-1 workover well, also on licence OML 40. Our current plan is to commence operations on this high quality asset in the second half of the year, and we anticipate that a successful workover will lead to our current forecast of gross production in the range of 5,000-10,000 barrels of oil per day from the Gbetiokun-1 well."
