Saudi tisht gas plays benefit from MSF

摘要

In 2007, Saudi Aramco installed the first openhole, multistage fracturing (MSF) completion systems in Saudi Arabia's deep, highly deviated gas wells (OGJ, June 11, 2011, p. 66). We chose MSF to maximize reservoir contact, completely cover the production interval, and ensure precise treatment fluid placement. Today, about 50 MSF completions support gas-development in the Southern Area of Saudi Arabia covering both the carbonate Khuff and the sandstone pre-Khuff reservoirs. Results have varied, but MSF wells have generally met or exceeded expectations.
