Course description

Applied Rock Mechanics - ARM

Rock mechanics is a vital decision-making tool for high-angle and horizontal drilling, unconventional reservoirs, deepwater drilling, massive hydraulic fracturing, and completing poorly cemented formations. Borehole instability, casing shear, subsidence, stuck pipe, and sand control issues cost the petroleum industry many billions of dollars annually. New theory and experimental methods as well as straightforward computer modeling techniques have provided insight into developing prospects in complex geological basins and harsh drilling environments.

 

In Applied Rock Mechanics, students are provided with basic theory, laboratory demonstrations, hands-on exercises, and computer modeling demonstrations. In addition to a comprehensive manual, software is provided for the student to perform wellbore stability calculations.

Suitability - Who should attend?

Petrophysicists, drilling engineers, completion engineers, exploration and development geologists, reservoir engineers, core and log analysts, geophysicists, and oil company research and development staff.

Training Course Content

Introduction to rock mechanics and geomechanical principals

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, 2D and 3D stress components, tensors, the stress ellipsoid, and basic rock failure (Mohr-Coulomb theory)

Rock mechanical properties: ability to bear stresses (compressive strength, tensile strength, deformation response to stresses), elastic moduli, Poisson's ratio

Pressure, stresses, and loads: principal stresses, in-situ stress regime, total-stress and effective-stress, temperature effects, nature, and origin of pore pressure

Geomechanics and structural geology: faulting and folding, tectonics, regional structural analysis, regional and localized stress

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

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

Stress orientation techniques: geological/mapping methods, wireline logging techniques, analastic strain recovery, differential strain curve analysis, acoustic anisotropy

Elastic, plastic, and viscous models of rock behavior: deformation mechanisms and common models used in petroleum related rock mechanics

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 demonstration)

Sand control: review of sand production mechanisms, completion techniques in unstable formations, gravel pack design, special liners and screens, and case histories

Fracture mechanics: naturally fractured reservoirs, hydraulic fracturing, stimulation options, and case history; Unconventional reservoir applications

Reservoir engineering applications: compaction drive, reservoir compaction and compressibility, subsidence, casing shear, depletion and effective stress, and case history

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 (lab demonstration); Data integration
