Abstract
Generally, assessing the properties of a plug comprising wellbore strengthening materials may enable the design of more efficient wellbore strengthening additives and fluids because the properties of the plug may translate to the near wellbore strengthening effect of the wellbore strengthening materials of the plug. Assessing such properties may involve applying a differential pressure to a plug formed in a passageway of a tool comprising at least one sensor proximal to the passageway plug, and then measuring at least one attribute selected from the group consisting of a normal plug pressure, a normal plug displacement, and any combination thereof with the at least one sensor.
