Course content
You will learn how to properly prepare core samples for laboratory experiments. Perform laboratory testing according to approved procedures. Get and analyze the results of a core study for geomechanical modeling.
Core research
During the course, you will gain practical skills in creating a 1D geomechanical model in the LithoStudio program. Learn to determine the mechanical properties and stress state of rocks based on logging data, reservoir tests and core studies.
1D geomechanics
You will become a specialist in 3D and 4D geomechanical modeling. Gain experience in analyzing the stress-strain state of rocks and changes in reservoir properties during field development, taking into account the structural features of geological development.
3D / 4D geomechanics
Training program
9 modules — from basic geomechanics to 1D / 3D / 4D modeling
Get acquainted with the science of geomechanics: a complex discipline covering the issues of geology, geophysics, petrophysics, and mechanics. You will learn how to solve a wide range of applied problems at different stages of field development using geomechanics.

Preparing core samples for the experiment
Module 2
You will be able to evaluate the quantity, quality and, if necessary, reject all transmitted geological and geophysical information, which will later be used to build a geomechanical model.
Module 3
Preparing data for geomechanical modeling
Correlation dependencies application
Preliminary stress assessment
Generating calibration information
Well logging data preparation methods
Initial information analysis
You will receive information on determining the prevailing stress regime to determine the required pressure gradient, direction and understanding of the complexity of the hydraulic fracture network created.
Module 4
Stress-strain state of rocks
Choosing the most stable well trajectory
Determining the directions of stresses
Conditions for the formation of technogenic fractures and falls
Tectonic regimes
Anderson concept
You will learn how to build a 1D geomechanical model: selection of the optimal drilling fluid density, forecasting of instability zones, potential drilling accidents and AHRP zones with a complex geological structure of the object under study.
Module 5
1D geomechanical modeling
Modeling of elastic and strength properties
Calibration to core data
Stress state calculation
Minimum horizontal stress calibration
Formation mechanisms and prediction of AHPV
Pore pressure
Overburden pressure
Building a mechanical facies model
You will receive the necessary foundation for planning drilling and hydraulic fracturing (HF) — learn how to calculate continuous profiles of the elastic-strength characteristics of rocks, as well as the stress state of a rock mass.
Module 6
Geomechanics for hydraulic fracturing optimization
Deviations and overhangs of fractures
Deformation and fluid leakage
Stress magnitude and proppant behavior
Dimensions and geometry of hydraulic fracturing
