Webinar: The Role of Coupled Geomechanical Modelling in Reservoir Simulation

This webinar discusses how to integrate important geomechanical data into a SAGD or a SteamFlood reservoir simulation study using CMG software.

Abstract

With growing emphasis on safe oilfield operations, especially in thermal processes such as SAGD and steam flooding, there is an increased focus on incorporating geomechanics into reservoir simulation studies. Traditionally, reservoir models have incorporated geomechanics by using a single rock compressibility, a simple dilation model or compaction tables. However, coupling rock mechanics with reservoir fluid flow is far more intricate than previously thought. In reality, both the porosity and permeability of the rock change as rock deformation increases and effective stress changes are experienced. To model these effects accurately, coupled geomechanics must be included as part of the simulation. Most commercial reservoir simulators cannot model these stress changes. By watching this webinar, you will learn how GEM and STARS can model coupled geomechanics to enable you identify optimal and safe operating conditions for your field operations.

The following main points were covered:

  • Various ways of coupling geomechanics with fluid flow
  • Methods to model permeability changes in reservoir
  • Dual grid system and geomechanical post-processing
  • Applications to caprock integrity in processes such as SAGD and CO2 sequestration
