Multi-technology solution generates USD 1.4 Million in revenue for operator in just six months
Challenge – Rod lift systems have their own challenges, especially in extreme conditions with excessive gas and high depths. Gas is compressed within the pump itself before actually producing liquid. Solids fallback is also an issue, particularly in the Bakken formation. The client had wells with pump set depth ranges from 8,500 feet to 9,800 feet (2,591 meters to 2,987 meters) and bottomhole temperatures around 190°F (88°C). The desired results were not achieved with rod pumps, so the client reconsidered ESPs using the latest technology from Summit ESP® – A Halliburton Service.
Solution – To achieve production goals, the Tiger Shark® SF320 pump was chosen for its larger shaft diameter. For the flow range, the larger shaft allows for greater torque, thus mitigating shaft breakage. The volute design diffuser provides high efficiency, while the wide vane configuration handles gas and solids more effectively. Liberator™ gas separators were used to separate as much gas as possible from the fluid prior to entering the pump. The Tiger Shark SFGH2500 gas handler was used for its open impeller stage design, which handles a higher percentage of free gas going into the pumps and requires less horsepower than competing gas handlers. For extended reliability, the Defender® super sand seal was added to this multi-technology solution. The super sand seal has exit ports located at the top of the mechanical seal to prevent the swirling effects of abrasives, which destroys shaft seals and radial bearings.
