KS field as the main oil producer in South Sumatera faces combination of gassy, sandy & low productivity challenges (proppant, hydraulically fractured) in TLS zone. Electric Submersible Pump short run-life were experienced due to these wells conditions. The shortest run-life 30 days operations occurred in ESP without any sand control, followed by pump stuck because of sand problem. These considerations are affecting the design of suitable ESP system by providing sand control, gas handler and low rate pump. There were two completion types selected in order to overcome the challenges. First type, applied in 7� casing by installing casing shroud to support natural separation of gas before entering the pump intake. Then hang sand screen to prevent sand intrusion into ESP string, and it helped in creating fluid velocity to provide the motor with sufficient cooling effect. The low productivity and gassy condition of the well was mitigated by setting the pump below perforation to improve pump submergence. The second type, applied in 5.5� casing since the ESP shroud is not applicable due to tight clearance. Retrievable packer is used to hang sand screen in 5.5� casing as lower completion. ESP string is at upper completion. Up to now, it is more than 13-wells were installed with these type of completions. Current average ESP run-life are 400-days, with the longest run life more than 700-days. This paper will describes an integrated application of ESP and sand control in sandy gassy wells with low productivity. These applications are required to improve the run-life of the ESP in TLS zone to minimize oil deferment.
