161793 – Integration of Drilling, Completion, and Stimulation Technology Boosts Saudi Arabian Gas Well Performance

Summary

This paper discusses multistage stimulation of horizontal wells in tight gas carbonate formations in Saudi Arabia, as the production results have shown significant improvements over conventional completion methods. The paper describes the process of changing the drilling azimuth from maximum to minimum stress to achieve desired fracturing objectives in mulstistage fracturing (MSF) assemblies. Actual data from wells completed with MSF demonstrates why the change in drilling direction was necessary and how the strategy was implemented.
