Course Contents:

               o Introduction to rock mechanics and geomechanical principals
               o Basic mechanics: Stress and strain, elasticity — linear and non-linear effects, brittle and

                   ductile rock behavior, poroelasticity, time-dependent-effects — consolidation and creep,

                    normal and shear

                  forces, hoop stresses, the Kirsch solution, 2-D and 3-D stress components, tensors, the stress

                  ellipsoid, and basic rock failure (Mohr-Coulomb theory)
               o Rock mechanical properties: Ability to bear stresses — compressive strength, tensile strength,

                  deformation response to stresses — elastic moduli, Poisson’s ratio
               o Pressure, stresses, and loads: Principal stresses, in-situ stress regime, total-stress and effective-

                   stress, temperature effects, nature and origin of pore pressure
               o Geomechanics and structural geology: Faulting and folding, tectonics, regional structural

                   analysis, regional and localized stress 

               o Wellbore and field measurement of in-situ (earth) stresses: Stresses around boreholes,

                   overburden stress, horizontal stresses, leakoff tests, mini-frac tests, formation testers,

                   other pressure transient techniques, and tool deployment
               o Overview of common rock mechanics tests (lab demonstrations): unconfined compression,

                    triaxial compression, hydrostatic compression, poly-axial, multi-stage triaxial, thick-walled

                    cylinder, direct tensile strength, indirect (Brazilian) tensile strength, direct shear,

                    uniaxial strain (compaction), and “quick look” (rock hardness) and “scratch” tests
               o Stress orientation techniques: Geological/mapping methods, wireline logging techniques,

                    analastic strain recovery, differential strain curve analysis, acoustic anisotropy
               o Elastic, plastic, and viscous models of rock behavior: Deformation mechanisms and

                    common models used in petroleum related rock mechanics
               o Borehole stability: Borehole stresses, wellbore placement, shale characterization, review

                    of borehole stability models, high angle and horizontal drilling, pilot hole evaluation,

                    multi-lateral wellbores, borehole breakouts, fluid-related instability, drilling through

                    depleted zones and casing shoe decisions, stuck pipe, and case histories (software


               o Sand control: Review of sand production mechanisms, completion techniques in unstable

                   formations, gravel pack design, special liners and screens, and case histories
               o Fracture mechanics: Naturally fractured reservoirs, hydraulic fracturing, stimulation

                    options, and case history
               o Reservoir engineering applications: Compaction drive, reservoir compaction and

                   compressibility, subsidence, casing shear, depletion and effective stress, and case history
               o Wireline log predicted mechanical properties: density logging, acoustic logging, Biot theory,

                  dipole and multi-pole (dynamic) acoustic logging, seismic data and Amplitude Versus Offset

                  (AVO), and shear- and compressional-wave anistropy
               o Data integration
