Geomechanics and Pore Pressure Prediction

Improve recovery and reduce exploitation costs. 

In order to ensure well stability and assess optimal orientation for fracture development, drilling professionals need to understand regional stress orientations and magnitudes, and how they affect rock properties in the formations around a wellbore.  The Geolog™ geomechanics functionality provides a comprehensive series of calculations and interactive tools that contribute to that understanding by assessing mechanical conditions around the wellbore.

Geomechanics are used worldwide by:

  • Geologists and petrophysicists
    • To estimate hydrocarbon column heights
    • To estimate fault seal potential
  • Drilling engineers
    • To determine optimally stable well drilling trajectories
    • To determine casing set points and mud programs
  • Reservoir engineers
    • To understand changes in reservoir performance during depletion
    • To improve recovery and reduce exploitation cost


  • Pore pressure prediction
    • Independent pre-drill validation of pore pressure within the familiar Geolog environment, providing input for other geomechanics workflows
    • Workflow consolidated into one integrated Loglan, for added efficiency
  • Dynamic and static elastic properties
    • Provides critical input to completions planning
  • Unconfined compressive strength
    • Provides critical input to completions planning and in-situ stress assessment
  •  In-situ stress estimation (multiple methods)
    • Provides critical input to wellbore stability workflows
  • Wellbore stability plots
    • Mud window:  Allows drillers to plan safe mud program: Avoid kicks, lost circulation, etc.
    • Stress plot:  A rapid, interactive plot to investigate wellbore conditions that could lead to failure
    • Stereonet plot:  A rapid, interactive plot to investigate how stable the wellbore will be for any given drilling direction
  • Published algorithms and ability to easily add custom relationships for all steps.
  • Calculations to support arbitrary wellbore orientations
