Geomechanics

What is reservoir geomechanics?

• From physical point of view, reservoir geomechanics studies stressed multiphase multicomponent media.
• From reservoir engineering point of view, it minimizes risks of catastrophic events caused by specific field development plan.
• From reservoir management point of view, it is a “corner stone” for Smart field technology.

A practical output of such vision (implicitly supported by oil and gas production community) is:

• Wellbore-scaled processes are often but not always closely related to the reservoir-scaled ones.
• Simple recipes are thus required to help a reservoir engineer find solutions for practical problems with taking into account all important processes in the minimal necessary way.
• The best way to develop such recipes is to construct so called “optimization” workflows were series of key parameters of various natures (physical, computational, numerical etc.) are identified.
• Playing with such parameters, an engineer could strongly simplify the physical and/or computational models and have rapid solutions at first with later turn back to more complex cases if needed.
