Geomechanics for Drilling Engineers - (Remote Instructor-Led Series)

Participants in this course will learn about the fundamentals ofGeomechanics and the role Geomechanics plays in well planning andoperations.  This course will cover thestress tensor, experimental rock mechanics, principal earth stresses, and the originsof pore pressure (including methods for measurement of pore pressure).  Other topics that will be covered in thiscourse include the concept and construction of Mechanical Earth Models (MEM),wellbore geomechanics, modes of rock deformation, and wellbore deformation.

This course will use lectures and case studies to help participantsamplify their learning and skills gained throughout this course. Participantswill learn from experts in the Geomechanics field about how to plan forwellbore stability, implement geomechanics solutions while drilling, and theconcepts of wellbore strengthening.


DAY 1: Fundamentals of Rock Mechanics, Stress Tensor, and Earth Stress

The course will begin with anintroduction to the fundamental aspect of rock mechanics including rock labtesting, and a review of the results that have been published in industry papers.  Participants will then learn about the stresstensor, constructing Mohr's Circle and analyzing stress, and elasticproperties, effective stress, and other rock mechanic fundamentals. Lastly theattendees will learn about principal earth stresses, the world stress map,Andersonian classification of faults, overburden stress, and horizontal stresses.


DAY 2: Pore Pressure & Fracture Gradient

The second day will begin withparticipants examining the detailed origins of pore pressure, measurement methods,estimation methods, vertical and horizontal methods, Eaton’s method, and areal-time pore pressure approach.

After that, the participants will learn about differentequations to compute fracture gradients and leak-off tests interpretations.


DAY 3: Mechanical Earth Model, Wellbore Geomechanics, and Wellbore Stability

On the third day participants will focus primarily on the Mechanical EarthModel (MEM), wellbore geomechanics, and wellbore stability issues.  This day will begin with participantsreviewing the concepts and construction of the MEM, including detailed data requirementsand required input data types.  With aworking MEM, the participant will then learn how to manage wellboregeomechanics and the state of stress in and around the wellbore. Modes of rockdeformation in the wellbore, the effects of well azimuth, and inclination willalso be covered.  Participants will alsolearn about basic geomechanics calculations. The day will end with participants reviewing wellbore deformation infractured rock masses and non-classical rock failures.


DAY 4: Drilling Geomechanics

On day four participants will learnabout downhole drilling geomechanics with particular emphasis being placed onplanning for wellbore stability and integration of geomechanics into thedrilling plan.  Participants will theninvestigate the intricacies of implementing real-time geomechanics whiledrilling.  Participants will also look athow geomechanics is used to provide well-bore strengthening in order to avoidmud losses in depleted formations.


This course is intended to benefit drilling personnel, such as drilling engineers and operations and planning engineers, involved in the planning of well operations.
