Geotechnical Laboratory Testing

for Salt Caverns

We are the only commercial lab in Canada to offer geomechanical testing for salt cavern.

BGES offers a full suite of geomechanical testing and analysis for salt cavern, potash, and other solution mining projects. Test programs are designed to evaluate major properties of the subsurface, including the permeability of the caprock and salt, Young’s modulus as well as compressive, tensile and shear strengths of the caprock and salt, and the salt’s unique creep behaviour.  Available tests include:

Constant Mean Stress Triaxial – Compression (CMS):
Determines stress values at failure by increasing axial stress while decreasing confining stress so that the mean stress during the test remains constant

Constant Mean Stress Triaxial – Extension (CMT):
Determines stress values at failure by reducing axial stress while increasing confining stress so that the mean stress during the test remains constant

Multi-Stage Creep Test (MSCT):
Provides a good understanding of both the transient and steady state creep behavior of the salt

Brazilian Indirect Tensile Strength (BITS) Test:
Measures the tensile strength of the salt

Unconfined Compressive Strength (UCS) Test:
Determines the lower end of the failure envelope (without confining stress)

Applications

Geomechanical tests provide essential inputs for numerical models and are therefore necessary to determine cavern integrity.

Features & Benefits

BGES is experienced in performing geotechnical testing for the oil & gas and mining industries. We are the only commercial lab in Canada offering geomechanical testing services for salt caverns. BGES’s Geoscience & Engineering team provides solutions both in the field and in the laboratory to obtain high-quality data as inputs for model development.

Operations

We understand the importance of conducting the tests correctly to obtain reliable results. Quality data starts with quality core and accurate in situ measurements. Diligent core handling and management is key to a successful lab test. Additional services provided by BGES include collecting the core at wellsite and transferring the core prudently for physical testing, providing a “chain of custody” and ultimately, a complete core analysis.
