FOCUSED CONSULTING Wellbore Stability Pore Pressure Prediction RELEVANT TRAINING Wellbore Stability and Geomechanics What’s New in GMI•WellCheck™ v. 2.5

GMI•Wellcheck analysis revealed that by increasing mud weight and using fracture link-up pressure as the upper bound for the mud window, the 13 3/4-inch and 9 5/8-inch casing depths could be extended, there by eliminating the need for the 11 3/4- inch casing string.

Protect yourself from costly complications such as stuck pipe, excessive reaming, lost circulation, fishing operations, and sidetracks.

Developed specifically for drilling engineers, GMI•WellCheck helps you incorporate wellbore stability into your well design, choosing casing seat depths and safe operating mud windows that optimize wellbore stability. Get priceless feedback regarding drilling parameter changes. Minimize project risk. Leverage your data from other applications.

• Finish on time and under budget
• Save millions in opportunity cost
• Avoid expensive failures
• Eliminate entire casing strings and other complexities

Make Better Casing Design Decisions

GMI•WellCheck makes it easy and intuitive to make the most profitable casing design decisions with an eye toward wellbore stability.

• Use either traditional pore pressure and fracture gradient or geomechanically calculated curves
• Choose either automatic or interactive casing design methods
• Define safe operating mud windows using kick tolerance and overbalance
• Import fracture gradients from other programs
• Evaluate impact of wellbore trajectory and sensitivity to mud weight and mud chemistry

Make the Most of Your Data

Integrate GMI•WellCheck into other design packages to maximize your return on information, including those from Sperry Drilling Services and Landmark's drilling suite:

• Import well trajectories from COMPASS™
• Import and export casing schemes
• Import pore pressure and fracture gradients from Presgraf™ or CasingSeat™
• Export pore pressure, collapse pressure, and fracture pressure gradients to CasingSeat
• Accelerate the well design process overall

The QRA features in GMI•WellCheck allow engineers to identify effective mud windows based on their probability of success. This type of risk-based analysis has become a standard throughout the industry and GMI•WellCheck provides a quick and easy way to perform these types of calculations for wellbore stability.

Quantitative Risk Assessment

GMI•WellCheck makes wellbore stability calculation fast and easy with Quantitative Risk Assessment (QRA). QRA functionality lets you run the numbers to get the most confidence for your plan by:

• Evaluating probability of wellbore instability and lost circulation as a function of mud weight
• Appraising models with Monte Carlo simulation
• Adjusting input parameter range for rock model confidence
• Identifying the most influential parameters
• Analyzing at a specific depth or over an entire open-hole interval
