• PoroMechanics Wellbore Stability
  Theories of coupled processes in geomechanics as applied to wellbore stability and virtual rock testing simulation. PBORE-3D is becoming the industry standard for wellbore analysis and design in real-time. It applies the coupled fluid flow and rock deformation analyses in the studies of wellbore stability and drilling mud design. Similarly, PCORE-3D is used for predicting time-dependent responses of (full/hollow) cylindrical samples in a variety of testing configurations and with different rock types. In addition, the tool helps tune the testing frame and pinpoint anomalies in the actual testing results

• Poromechanics rock characterization
  The POROC-QSD tool is being formulated to assist in determining the (full dynamic and quasi-static) physical and mechanical parameters from MWD and LWD in real-time. As such, the tool can be used to calculate the poromechanics rock characteristics directly from well logs and is being designed to work coherently with our other poromechanical packages. Also an online version of POROC-QSD is available.

• Reservoir Management/ Wellbore Stability in Naturally Fractured Reservoir Rocks
  Coupled flow and deformation in complex (fractured) formations and in multi-phase fluid flow situations. Our tool IASRS encompasses numerical models that allow a 3-D simulation of fluid saturated naturally fractured rock formation from wellbore stability to reservoir production to reservoir subsidence. The software simulates coupled processes in reservoir rock deformation and wellbore stability in fractured formations.

• ABAQUS Finite Element Modelling
  Finite element modeling of petroleum, geology and geotechnical problems using ABAQUS. The ABAQUS code is a general-purpose, nonlinear finite element analysis program. It can handle 2-D & 3-D, static & dynamic, stress/displacement, coupled pore fluid flow and stress, as well as heat transfer and thermal stress analysis. The analysis materials can be isotropic & anisotropic, elastic (visco-, hypo-, hyper-, etc.) & plastic. ABAQUS has been used to analyze wellbore (petroleum), listric fault (geology) and dynamic compaction (geotechnical).

• Shale Testing
  Developing new technologies in shale testing and shale properties measurement. The PMI laboratory testing facilities allow testing of large shale samples (up to 8"X20") in thick hollow cylinder geometry under simulated in-situ wellbore conditions with 20,000 psi confining pressure and at testing temperatures as high as 200°C. Our facilities also allow testing small (1") plugs of rocks.

• Mechanics of Soft Sediments
  Investigating the mechanics of soft sediments and sanding assessment during oil and gas production. The Undrained Sanding Criteria (USC) is a new and innovative test procedure that allows characterizing strength properties of soft sediments and weak rocks as well as assessing the susceptibility of the formation to sanding during production.

• PoroMechanics Laboratory
  The poromechanics laboratory facility includes over 5 million dollars of testing equipment for acquisition of acoustic mission, ultrasonic tomography, acoustic velocity, and permeability of rock samples subjected to simulated downhole conditions. The equipment includes a three-million pound capacity load frame, two 600,000 lb. load frames, two 50,000 lb. load frames, and a large polyaxial cubic cell.
