Artificial Lift Selection in the Khesht Field

The Khesht field was discovered in 1992 and located some 25 km from Kazeron town. One reservoir (Asmari) was found to be hydrocarbon bearing in the field. The discovery well also tested to a production rate of 9,450 barrels of oil per day. Artificial lift method selection is very important. An improper selection of artificial lift can reduce production and increase the operating cost substantially. Once a decision has been made on the type to install on a well, it can be rarely altered whether or not the method selected was and still is the optimal for the existing conditions. The authors present the screening criteria on the different artificial lift techniques and discuss among them to choices suitable technique to apply in the field. A comparison among natural flow, electrical submersible pump, and gas lift will present for the Khesht field only to help in reaching the conclusions to verify the best solution to produce the wells. In this study the production rates are the only factor in determining the best well completion. Reservoir simulation model was used to predict the performance of different artificial lift methods.
