COURSE DESCRIPTION

Geomechanics is a key technology to minimize risk and reduce cost in all petroleum operations from exploration to production. Geomechanics importance is even more pronounced when the low oil price creates harsh economic condition. It has been reported that geomechanics is saving several billions of dollars every year by preventing problems such as borehole failure, stuck pipe/tool, sidetracking, lost circulation, casing collapse, sand production, reservoir compaction, permeability reduction, and surface subsidence. This requires good understanding of the interaction between rock mechanical properties, in?situ stresses and petroleum operations. This multi-disciplinary course provides a concise overview of basic rock mechanics and its application to several practical problems encountered at well and field scales. This is an interactive course which will be presented in two modules: First module discusses building geomechanical models including rock property modeling, pore pressure prediction, and in-situ stress modeling; the second module reviews the applications such as wellbore stability, sand production prediction, hydraulic fracturing, naturally fractured reservoirs, and compaction-subsidence analyses.

WHO SHOULD ATTEND

  • Drilling, reservoir, completion, exploitation, and production engineers
  • Geoscientists, geologists, geophysicists, and petrophysicists
  • Field development managers, technical advisors, core lab personnel

WHAT YOU WILL LEARN

Module I: Principals of Rock Mechanics and Geomechanical Earth Modeling

This module provides an introduction to the importance of geomechanics for oil and gas industry, relevant rock mechanics theories and geomechanical modeling. You will learn how to integrate geological, petrophysical and drilling information, in conjunction with well logs and core data from off-set wells to construct 1D to 3D geomechanical models. You will also learn how to verify and calibrate the model with drilling incidents and regional information.

Module II: Geomechanics Applications in Field Development

In this module, different applications of geomechanics in oil and gas field development will be discussed and several interesting case studies will be shared. This module gives you detailed information about wellbore stability, sand production prediction, hydraulic fracturing, maximizing production from natural fractures, well trajectory optimization, compaction, casing collapse and subsidence studies. You will learn how to analyze wellbore stability for generic and optimum well trajectories and define a safe operating mud weight window to minimize drilling problems; how to design well trajectory to maximize production from natural fractures; to predict and control the orientation and extension of hydraulic fractures; to evaluate the potential for sand production and how to manage it using selective or/and oriented perforation strategies.
