STRESSPATH EXAMPLE - RESERVOIR YIELD
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.
