OPTIMIZATION OF WELL TRAJECTORY AND MUD WEIGHT USING INTEGRATED MECHANICAL EARTH MODEL: A CASE STUDY FROM THE GULF OF SUEZ

Abstract

The Wellbore stability problems cost the petroleum industry billions of US dollars each year. Those problems range from drilling operations, completion and production, workovers, to EOR (Enhanced Oil Recovery). The expected problems are borehole breakout or collapse, drill pipe sticking, sand production, formation compaction, casing collapse, etc.... In the presented research; three fields from the south central of Gulf of Suez have been studied, focusing on the wellbore stability occurred while drilling, to predict the optimum mud weight window for each inclination and azimuth, stability of the rock for underbalance drilling, and anticipated drilling problems
