Overview

ARM: Applied Rock Mechanics

About the Course

 In all stages of the development of a petroleum reservoir, a thorough understanding of the stress, strain, and failure mechanics of rocks as well as how they react to earth forces can be extremely profitable. Rock mechanics has become a vital technique over the past 10 years, able to reduce financial risk in drilling and well completions, identify chances for exploration and development, and increase hydrocarbon productivity.

For high-angle and horizontal drilling, unconventional reservoirs, deepwater drilling, huge hydraulic fracturing, and finishing poorly cemented formations, rock mechanics is an essential decision-making tool. The petroleum sector loses many billions of dollars every year due to problems with sand control, clogged pipes, subsidence, casing shear, and borehole instability. Simple computer modeling approaches, new theory, and practical methodologies have shed light on developing prospects in challenging drilling settings and complex geological basins. Basic theory, laboratory exercises, hands-on activities, and computer modeling demonstrations are all offered to students in Applied Rock Mechanics. Software is supplied for the student to do wellbore stability calculations in addition to a thorough manual. It is underlined how useful rock mechanics is in real life. Engineers and geoscientists can become acquainted with the necessary equipment for rapid field use by reading Applied Rock Mechanics.

 Target Audience

 geophysicists, drilling engineers, completion engineers, reservoir engineers, exploration and development geologists, core and log analysts, and research and development personnel from oil companies.

 Course Objectives

Participants will pick up skills in:

•  Analyze the mechanics of rock stress, strain, and failure.
• Utilize the principles of rock mechanics to produce economic gains throughout the reservoir development process.

Course Outlines

•  introduction to geomechanical principles and rock mechanics
• Basic mechanics include the following concepts: stress and strain, elasticity (linear and non-linear effects, brittle and ductile rock behavior, poroelasticity, and 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 fundamental rock failure (Mohr-Coulomb theory).
• Rock mechanical properties: elastic moduli, Poisson's ratio, and capacity to withstand stresses (compressive strength, tensile strength, and deformation response to stresses).
• Principal stresses, in-situ stress regime, total stress and effective stress, temperature impacts, nature, and genesis of pore pressure are among the stresses and loads that are discussed.
• Faulting and folding, tectonics, regional structural analysis, and localized and regional stress are all aspects of geomechanics and structural geology.
• Leakoff tests, mini-frac tests, formation testers, other pressure transient techniques, and tool deployment are some examples of the in-situ (earth) stresses that can be measured in the field and through wellbore drilling.
• An overview of typical rock mechanics tests (lab examples) Uniaxial strain (compaction), unconfined compression, triaxial compression, hydrostatic compression, poly-axial, multi-stage triaxial, thick-walled cylinder, direct tensile strength, indirect (Brazilian) tensile strength, direct shear, rapid glance (rock hardness), and scratch tests.
• Techniques for stress orientation include acoustic anisotropy, wireline logging, analastic strain recovery, differential strain curve analysis, and geological/mapping methods.
• Rock deformation mechanisms and prevalent models used in petroleum-related rock mechanics: elastic, plastic, and viscous models of rock behavior
• For example, 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 studies (software demonstration) are all related to borehole stability.
• Review of sand production mechanisms, completion methods for shaky formations, gravel pack design, unique liners and filters, and case studies are all examples of ways to regulate sand.
• Natural fractured reservoirs, hydraulic fracturing, stimulation choices, and case history are examples of fracture mechanics.
• applications for unconventional reservoirs
• Applications of reservoir engineering: case studies, subsidence, casing shear, depletion and effective stress, compaction drive, and reservoir compaction and compressibility
• Biot theory, dipole and multi-pole (dynamic) acoustic logging, seismic data, Amplitude Versus Offset (AVO), and shear- and compressional-wave anistropy (lab demonstration) were all used to forecast mechanical parameters for wireline logs.
