Overview: A North Sea operator intended to drill a large-diameter well in an area where wellbore (in)stability was an issue. Previously, problems were experienced while drilling a deep shale formation at high hole angles. A wellbore (in)stability study was performed to help optimize mud weight requirements in the intermediate intervals, and mud weight ranges were identified to aid in minimizing drilling problems.
