The paper details the application of the hypercleaning process as a stimulation technique in the Duri Field. The Duri Field is the second biggest field in Indonesia, and is the largest steamdrive in the world. Currently it has over 1050 active producers in 336 steamflood patterns. Production of the low gravity crude is from shallow unconsolidated sands which require gravel packed completions.The hypercleaning process is the use of focused high pressure water jets to clean scale and debris from the slots or perforations of oilwell liners. The process was originally developed in California for cleaning plugged liners in heavy oil, thermal enhanced recovery projects. It has been shown to be capable of cleaning sand, scalc, clays, and coke like asphaltine deposits from the machine cut slots of liners'.?. However, . the completion technique used in the Duri field is significantly different from those used in California's heavy oil fields. This paper documents the successful widespread use of hypercleaning to remove scale and debris from pipe based screen liners in the Duri Field. Typical stimulation results, successful candidate selection criteria, and statistical data concerning overall success rate are presented.Also documented are attempts which have been made to optimize the hypercleaning process for Duri conditions. Suggestions for further optimization are also presented in this paper.
