Following simulation of the stress state during the geologic burial history, the depletion stress path can be modeled to determine when reservoir yield is anticipated over the life of a well. Accelerated compaction is often associated with yielding of the reservoir, and can be responsible for a variety of geomechanical problems.
Reservoir stress state during depletion plotted relative to rock strength envelope in stress invariant coordinates. In this example, yielding occurs after 2000 psi of reservoir depletion.
