High Pressure Triaxial Test
Rock Fluid Imaging Lab provides geomechanical modeling laboratory service as advanced access tools in some unconventional reservoir characterization (Fracture and Shale Gas), soil/wellbore stability analysis and other rock mechanics case.

Application in Oil and Gas:
- Assess reservoir rock strength and stiffness: This helps engineers understand the ability of the reservoir rock to withstand the pressures and stresses of production and injection.
- Simulate in-situ stress conditions: The test can simulate the stress state of the reservoir at different depths and under varying production scenarios. Therefore, the critical stresses of a well can be analyzed.
- Evaluate the impact of drilling and fracturing: The test is used to analyze reservoir integrity and potential for hydrocarbon production.
- Determine rock properties: This information is crucial for reservoir modeling, well planning, and production optimization.

Triaxial tests (SST, MST) are used to determine rock failure parameters, principally Mohr-Coulomb cohesive strength and friction angle, under representative reservoir loading/stress conditions, Unconfined Compressive Strength (UCS) from extrapolation of confined failure strengths, and static elastic moduli—Young’s modulus and Poisson’s ratio—under representative reservoir loading/stress conditions.
