A collapse pressure prediction model for horizontal shale gas wells with multiple weak planes

A collapse pressure prediction model for horizontal shale gas wells with multiple weak planes

Since collapse of horizontal wellbore through long brittle shale interval is a major problem, the occurrence characteristics of weak planes were analyzed according to outcrop, core, and SEM and FMI data of shale rocks. A strength analysis method was developed for shale rocks with multiple weak plane...
