Erin Energy Corp., the Houston-based firm formerly known as Camac Energy Inc., has started production from the Oyo-7 well in OML 120 offshore Nigeria. Erin Energy operates Oyo field with 100% interest.
Oyo-7 was drilled by Transocean Ltd.’s Sedco Express semisubmersible rig to a total depth of 2,438 m and successfully completed horizontally in the Pliocene formation (OGJ Online, Dec. 4, 2014). The rig also will drill the Oyo-8 development well.
Oyo-7 is in 300 m of water and is producing into the Armada Perdana floating production, storage, and offloading vessel, which has a production capacity of 40,000 b/d and storage capacity of 1.1 million bbl (OGJ Online, Feb. 19, 2014). The well is expected to produce 7,000 bo/d following optimization of choke size.
The company says its primary objective in drilling Oyo-7 was to target the Pliocene formation from which it is now producing (OGJ Online, Oct. 16, 2013), while the secondary objective was to test the deeper Miocene formation for hydrocarbon potential.
Oyo-7 successfully confirmed hydrocarbon in the Miocene formation, which was previously undrilled on the block (OGJ Online, Nov. 13, 2013). Erin Energy says the successful test has derisked the Miocene in the company’s offshore Nigeria blocks and has provided valuable data for its planned Miocene exploration program, which targets recoverable P50 resources of nearly 3 billion boe.
Drilling of the company’s first Miocene exploration well is slated for the fourth quarter.
