Testing for rock mechanical propertiesGeomechanical Testing Services / Advisory
Advanced Geotechnology is part of Weatherford's Core Evaluation Services team which includes the world-class facilities of Hycal Energy Research Laboratories Ltd. in Calgary, Alberta and Omni Laboratories, Inc. in Houston, Texas.  We are experts in the design and management of geomechanical testing programs and would be pleased to discuss your needs or direct you to the appropriate contacts in our sister companies.
We have specialized expertise in the following types of tests:
Rock strength tests
  • Unconfined compressive strength (UCS)
  • Triaxial compressive strength
  • Direct shear tests
  • Thick-walled cylinder strength
Rock fracture toughness

Shale swelling behavior
  • Oedometer cell
  • Triaxial cell
Static deformation properties
  • Young's modulus
  • Poisson's ratio
  • Bulk, pore and rock compressibilities
Ultrasonic velocities*
  • Compression velocities at stress
  • Shear velocities at stress
  • Point load circumferential velocities
