Borehole wall tensile caving instability in the horizontal well of deep brittle shale

INTRODUCTION: With the increasing drilling depth of shale formation, downhole collapse is a frequent occurrence, which often manifests as borehole wall caving. METHODS: We used the deep shale of the Longmaxi Formation to conduct the mechanical loading and unloading experiments under different downho...
