Screen Liner Application in Down Hole Pump Assembly in Air Serdang Wells, PHE Ogan Komering

Abstrak

Ogan Komering Block, operated by Pertamina Hulu Energy (Ogan Komering) Ltd., is located in South Sumatera, approximately 40 km south of Prabumulih, covered 1,155 km² working area. The Air Serdang field as one of fields in PHE Ogan Komering Area has been producing from Baturaja Formation (BRF carbonate) and Talang Akar Formation (TAF sand) which is consist of sand-stones with range from fine to coarsely grained, and are generally well sorted with good porosity (14% - 22%) and permeability (10 mD - 300 mD). The sand produced from Talang Akar Formation has been influencing performance of the wells due to decreasing well production, formation damage and equipment failures. Several efforts in sand control methods have being tried to reduce the problem. Through the new application of wire-wrapped screen liner installed in the downhole pump, it minimizes the sand problem, improve the oil production and save the well cost operation due to well & equipment failures. This application is to easy, practice in installation & operation and cheaper than other applied sand control methods. In this paper, the successful of this application will be compared with the previous sand control method (sandtrap) based on run life of the well, production impact and cost saving due to reducing impact of well & equipment failures. It also compares the best of wire-wrapped screen slot opening size based on slot opening size ever installed in the oil well to look for the appropriate screen liner size for the future of better sand control method at wells in Air Serdang Field area in particular and Ogan Komering block in general.
