Investigation of the Effect of Drilling Mud Pressure on the Stability of the Walls of the Directional Well in the Southern Iranian Oil Field- Cheshmeh Khosh

Rapid increasing demand for energy necessitates the development of oil and gas fields in a more accurate and reliable method which includes the optimization of drilling and production operations in conjunction with enhanced oil recovery methods. The technique of directional drilling plays a significant role in this regard and affects the drilling performance and producing wells. Prevention of the destruction and damages on the walls of the well is an important task including the selection of the optimal pressure of drilling mud to be injected.In this study we investigated and modeled one of the directional wells in the Southern Iranian oil field-Cheshmeh Khosh; which includes the determination of the role and effect of drilling mud pressure on the extent of formation damage. The results of the study show that optimal injection pressure of 60 Mpa give better out comes specifically reduces the displacement of points on the walls.
