Abstract: This invention relates to a downhole hydraulic pump for hydrocarbon wells that is installed and operated using coiled tubing. The downhole hydraulic pump is driven by a hydraulic power system positioned at the surface and connected through a closed loop system using multiple channels of the coiled tubing. The coiled tubing is formed of a combination of channels including strength component such as steel and having one channel that is at least lined with a non-metallic corrosion resistant surface where clean hydraulic fluid is carried from the hydraulic power system to the downhole hydraulic pump through the non-metallic corrosion resistant channel so to be less likely to pick up manufacturing and environmental particulates and corrosion by-products within the channel carrying the hydraulic fluid to the downhole hydraulic pump. The non-metallic corrosion resistant lined channel may comprise plastic pipe.

Abstract: This invention relates to a coiled tubing installed and operated hydraulically driven downhole pump for hydrocarbon wells and especially hydrocarbon gas wells that are prone to produce fluids that choke gas production. The hydraulically driven downhole pump is driven by a closed loop surface positioned hydraulic power system. Should the hydraulically driven downhole pump become inoperative, it may be quickly retrieved and immediately replaced using a coiled tubing unit as compared to a workover rig. A coiled tubing unit is able to pull the coiled tubing string and re-install the string quite rapidly because the coiled tubing does not have joints that need to be disassembled or reconnected. The manpower needs and costs for replacement are considerably less and lost production of the well is substantially reduced.
