  • Introduction



  The Geomechanics laboratory of Amirkabir University of Technology (AUT) is one of the most equipped laboratories for geomechanical experiments in Iran. Geomechanics Laboratory is directed by Dr. Mohammadjavad Ameri who is a faculty member in the department of petroleum engineering at Amirkabir University of Technology.

Beside sample preparation equipment, the AUT Geomechanics laboratory is equipped with an Autonomous Triaxial Cell (ATC), a Membrane Efficiency Screening Equipment (MESE), a Mud Cake Characterization Equipment (MCCE) and an automatic uniaxial loading system, a laser profilometer system, and a fracture conductivity measurement system. In this laboratory, various researches on geomechanical problems with applications in the oil and gas industry including characterization of rock mechanical properties, developing poro-mechanical constitutive models for rocks, evaluating chemo-poroelastic properties of swelling shales, chemo-poroelastic modeling and simulation of water sensitive rocks such as some shales, modeling and simulation of hydraulic fracturing in rocks, designing water-based swelling inhibition drilling muds, wellbore stability and developing Mechanical Earth Model (MEM) for wells analysis, are conducted.

Based on the available equipment in the AUT geomechanics laboratory, the following tests are conducted in this laboratory:

 

  • Coring and preparing rock samples for geomechanical tests according to the ISRM standards.
  • Unconfined compression test.
  • Drained and undrained single stage triaxial compression test at different confining pressures and temperatures.
  • Drained, undrained and unjacketed hydrostatic compression test at different confining pressures and temperatures.
  • Multi-stage triaxial compression test.
  • Multi-stage triaxial shear test.
  • Brazilian tensile strength test.
  • Hydraulic tensile strength test.
  • Point load test.
  • Semi-circular bending (SCB) test for mode I fracture toughness measurement.
  • Pore pressure transmission test.
  • Measuring shale membrane efficiency.
  • Permeability measurement of tight samples in the nano-Darcy range.
  • Determination of the solute diffusion coefficient in rock samples.
  • Measuring physical properties of mud cake.
