JewelSuite Geomechanics provides a proven workflow to help ou optimize your well plans and define a safe operating window to maximize drilling performance, minimize drilling risk and improve safety. With it, you can create geomechanical models and analyze wellbore stability from well logs and drilling data. It replaces the functionality provided by GMI WellCheck and GMI ModelBuilder and adds additional advanced functionality, including real-time WITSML.

Overview

JewelSuite is an integrated environment for geomodeling, reservoir engineering, and geomechanics. The Geomechanics module focuses on building Mechanical Earth Models (MEMs) and performing stress‑related simulations to support drilling and reservoir management.

Key Capabilities

1. Mechanical Earth Model (MEM) Construction

• Builds 1D, 2D, and 3D geomechanical models.
• Integrates data from:
  • Well logs
  • Core measurements
  • Seismic data
  • Geological models
• Calculates rock mechanical properties such as:
  • Young’s modulus
  • Poisson’s ratio
  • Unconfined compressive strength (UCS)
  • Pore pressure
  • In‑situ stresses

2. Wellbore Stability Analysis

• Predicts safe mud weight windows to avoid:
  • Borehole collapse
  • Fracturing
• Supports trajectory optimization for directional wells.

3. Stress and Strain Modeling

• Simulates regional stress fields in reservoirs.
• Evaluates how faults, fractures, and reservoir depletion affect stress.

4. Reservoir Geomechanics

• Couples with reservoir simulation models to analyze:
  • Compaction and subsidence
  • Fault reactivation
  • Caprock integrity
  • Sand production risk

5. Hydraulic Fracturing Support

• Predicts fracture initiation pressure.
• Helps design stimulation programs.

6. Drilling Risk Management

• Assists with:
  • Wellbore strengthening
  • Lost circulation prediction
  • Managed pressure drilling planning

Integration

JewelSuite Geomechanics integrates with other JewelSuite modules such as:

• JewelSuite Geology – structural and stratigraphic models
• JewelSuite Reservoir Engineering – flow simulation
• JewelSuite Uncertainty – probabilistic modeling

This integration allows fully coupled workflows, where geological models feed geomechanical analysis.

Typical Workflow

1. Import geological and well data.
2. Build a Mechanical Earth Model (MEM).
3. Calibrate model using well observations.
4. Analyze wellbore stability and stresses.
5. Run reservoir depletion or stimulation scenarios.
6. Use results to optimize drilling or field development.
