Collapse Pressure Distribution along a Deep Horizontal Coalbed Methane Well in the Daning-Jixian Block

Collapse-pressure estimation is essential for managing wellbore instability in coalbed methane (CBM) drilling, where weak, stress-sensitive coal formations present major operational risks. This study develops an analytical model to evaluate collapse pressure using the Mohr-Coulomb (MC) and Mogi-Coulomb (Mg-C) failure c...
