This course provides an introduction of to pics related to drilling geomechanics. It is recommended for reservoir, pr oduction, drilling and completion engineers, earth scientists, asset team managers and other oilfield professionals who want to understand the basic principles of rock mechanics as it applies to drilling wells safely. It i s especially useful for people who do not have a geomechanics background o r hands-on experience in determining rock properties from the lab/log data or in designing mud weights for vertical or inclined wellbores.
Th e course describes the step-by-step procedure for developing a 1-D mechani cal earth model starting from log data and integrating available lab and d rilling data for calibration.
The course will focus on the followin g topics:
- Fundamentals of Rock Mechanics and its Applicat ions: normal and shear stresses on a plane, 1-D, 2-D and 3-D stre sses, Mohr&rsquo\;s circle for calculating stresses on a plane, principal stresses, and effective stresses. Review of various rock mechanics applica tions in the petroleum industry.
- Earth Stresses: in-situ vertical and horizontal stresses, their estimation from logs and calibration with field data\; different stress faulting regimes, and geolo gical evidences.
- Rock Strength Parameters: uncon fined compressive strength, cohesion and friction angle, Young&rsquo\;s mo dulus, Poisson&rsquo\;s ratio, and their estimation from log and lab-based methods\; static vs. dynamic properties, etc.
- Laboratory Testing: characterization of rock mechanical properties from lab tests, such as load and deformation measurements, elastic and failure par ameter determination from triaxial tests, and other tests (hydrostatic, un iaxial, pore volume compressibility).
- Log Based Parameter s: estimating elastic rock mechanical properties from standard so nic and density log measurements, dynamic vs. static rock properties and c alibration with lab data.
- Wellbore Stresses: ind uced stresses due to drilling a hole &ndash\; hoop (tangential or circumfe rential) and radial stresses\; mechanisms of borehole failure such as brea kouts or shear failure, drilling induced fractures, lost circulation probl ems, breathing and ballooning\; LOT/FIT/Mini-frac, closure stress determin ation, field data calibration\; failure types and models, Mohr&rsquo\;s ci rcle to explain rock failure types and effect of mud weight and other para meters on rock failure.
- Mud Window: collapse and tensile failure limits, frac gradient, failure criteria, mud weight windo w, tight holes, lost circulation, etc.
If time permits, the followi ng additional topics may be covered:
- Well Inclination and Depletion Effects: effect of well inclination and depletion on c ollapse mud weight and frac gradient, and on mud weight window\; narrow mu d weight window, enhancing mud weight window with stress caging or wellbor e strengthening, etc.
- Case Studies: appropriate case studies to demonstrate the various aspects of the course.
