Utilize four-arm and six-arm caliper analysis to understand breakouts, distinguishing them from other borehole features for more profitable decision-making.

GMI•Caliper performs rapid analysis of four-arm and six-arm caliper data to determine the orientation and extent of stress-induced wellbore breakouts. GMI•Caliper can automatically discriminate among wellbore breakouts, washouts, and pipe wear along the borehole wall. An easy-to-use set of statistical functions provides quantitative values of breakout distribution over any desired depth range. The results of GMI•Caliper's interactive breakout identification provide critical constraints on in-situ stress and rock strength for the analysis of wellbore stability, fracture permeability, reservoir performance, and fault seal integrity.

Instantly determine orientation and extent of stress-induced wellbore breakouts understanding the issues, making better decisions and reaching total depth more profitably. Differentiate breakout features from washouts and pipe wear along the borehole wall, and get quantitative values of breakout distribution over any depth range, as the program delivers critical constraints on in-situ stress and rock strength.

GMI•Caliper is critical for optimizing:

• Reservoir performance
• Wellbore stability
• Fault seal integrity
• Fracture permeability

Simplify Wellbore Breakout Data

The interpretation of six-arm caliper data for breakout identification is significantly more complicated than the interpretation of four-arm data. GMI•Caliper implements an innovative new analysis technique for detecting breakouts in six-arm caliper data. Our proprietary algorithm utilizes the individual caliper measurements from each arm to align the tool center with the borehole axis and differentiate between symmetrical elongations (wellbore breakouts) and asymmetrical elongations (keyseats).

GMI•Caliper's user interface is simple, offering a comprehensive and complementary set of plots for quick interpretation. Customized parameters with scalable profile view, histogram, and polar view displays help you see data in a way that makes sense.

• Input standard LAS or ASCII four- and six-arm caliper data measured from standard dipmeter tools
• Save breakout directions as ASCII text
• Present analysis results in plots which may be printed, copied, and saved directly from the application to optimize workflow
• Customize displays with flexible unit and reference plot systems
• Run separate analyses on user-defined sections of the data for focused interpretation

Interpret with Flexibility

Top: Polar cross section at 2,506.65 m MD from acoustic image data. Right: Six-arm caliper data recorded over the interval 2,500 - 2,520 meters in the same borehole.

Choose from a comprehensive set of plots for both four arm and six arm caliper data:

• Pad Stacked Well Plot: Shows pad location over the entire analyzed interval projected onto a cross-section of the wellbore
• Breakout Stacked Well Plot: Shows breakout position over the entire analyzed interval projected onto a cross-section of the wellbore
• Breakout Histogram Plot or Rose Plot: Shows the frequency of breakouts as a function of breakout azimuth over the entire analyzed depth interval
