Objective/Scope: Challenges of sucker rod pumping operation in high gas and solid production;The implementation of integrated down-hole gas and solid separation in one device. Method procedure/processes: Old Rimau Fields in South Sumatera produce oil from sandstone reservoir with GOR above 800 scf/stb and solid production resulted from fracturing proppant flow back. Due to these conditions, some problems such as gas lock or interference, pump leakage, and rod parted were discovered which resulting in low SRP run life. The installation of sand screen and gas anchor has been implemented to encounter this issue. However, this initiative still ineffective due to limited conditions. If the sand screen was installed to control the sand, then the gas anchor to control the gas could not be installed and vice versa.Results, observations, conclusions: Integrated solid and gas handling called "hybrid" device has been introduced. The device is connected directly at the bottom of down-hole pump consist of three section, the upper section for intake and gas separator, the middle section for gas and solid separator, and lower one for solid container. The first utilization was conducted in three SRP wells, which are KG-09, LKP-21, and KG-10. Previously, these wells were shut-in due to down-hole problem. After installing the device while well service, the SRP run normally to produce the oil. The increasing of pump load performance was also obtained, indicated by the dyna card. At this time, the SRP is still running and run life is still under surveillance. This paper will explain the new technology end-to-end implementation of the integrated down-hole sand and gas control in one device for Sucker Rod Pump (SRP) system.
