Managing Wellbore Temperatures May Increase Effective Fracture Gradients: Drilling operations cause changes in well-bore temperatures that can significantly impact effective fracture gradients. Some of these adverse thermal effects can be managed by adjusting parameters of the drilling process such as mud properties and hydraulics. As thermal management systems are adopted and used in the industry to minimize lost...; Tags: Landmark Graphics Corp., Fracture Gradient, Strategy, Management; White papers 2004-09-07

The Difference Between Fracture Gradient and Wellbore Pressure Containment and the Effect on Drilling Beyond Natural Pressure Limits: In this paper, the difference between Fracture gradient FG and Wellbore pressure containment WPC is analyzed and illustrated using literature and field data. Solutions for improving WPC are presented. The potential for cost savings from improved wellbore pressure containment is also demonstrated. Wellbore pressure containment WPC is the maximum allowable...; Tags: Factor, Difference, Wellbore Pressure Containment, Construction; White papers 2003-02-11
