With the considerable push of oil and gas exploration to the new frontiers, the greater uncertainties and narrower drilling margin need a thorough integrated assessment to different aspects of wellbore strengthening behavior. In this pursuit of addressing several wellbore issues, the behavior of formation rock is of immense importance. Before looking into the underlying behavior, one has to understand the formation properties, hydraulic communication, and formation properties of the rock samples. These critical properties effect the sealing behavior and post sealing strength of the borehole wall. After the evaluation of formation properties in the experimental setup, the near wellbore behavior can be studied.
