Egdon Resources, an oil and gas producer onshore UK, resumed production operations following the successful installation of Wanner’s hydraulic jet pump artificial lift solution at its Wressle-1 oil well.
Wressle-1, an S-shaped well, with a 45 o inclination, was drilled to a TD of 2249m MD and completed for production with a 4-1/2” liner and 2-7/8” tubing.
Wressle-1 was placed on production in 2021 and had been producing for two and a half years with no issues until, water break-through occurred, significantly impacting on oil production.
Having considered several artificial lift technology options, Egdon selected the Wanner solution. The lifting system consists of a free-style downhole jet pump, together with a Hydra-Cell Pro seal-less and packing-free surface power fluid pump.
With no moving parts downhole, the jet pump is compact, rig-free and uses pressurised fluid. The jet pump itself requires minimal maintenance. It can be easily retrieved hydraulically and circulated to the surface by reversing the flow of the power fluid, negating the need to pull tubing.
It can accommodate tight turns, up to 70° inclination and is as reliable in deviated as vertical wellbores. The advantage over other artificial lift options such as a beam pump, is that higher fluid volumes can be returned to surface.
Installation of the jet pump is straight forward and cost effective – it doesn’t require a workover rig, pulling unit or slick-line to run and retrieve the pump. This eliminates costly operating and workover costs. It also benefits from comprehensive and expert engineering support.
Following the successful installation of the jet pump, production operations were reinstated, with Wressle-1 producing in excess of 400 barrels of oil per day.
Taha Metwally, Wanner’s Artificial Lift Business Development Manager, said: “It is more important than ever that we improve energy security efficiently and effectively and the Wressle well is doing exactly that with our artificial lift solution.”
“This solution has completely mitigated the mechanical problems and production limitations frequently associated with a rod pumping system in an S-shaped well.
“Our rig-less, surface pump and jet pump solution can optimise oil and gas production that would otherwise be compromised; lowering the total cost of lifting a barrel of fluid.”
Martin Durham, Technical Director of Egdon Resources, added: “It was a great operational achievement to successfully implement Wanner’s hydraulic artificial lift jet pump technology. This has enabled production to be reinstated, and we are now producing oil efficiently.”
