... Abstract A large number of studies have shown that there are numerous cleavage planes and cracks in coal rock, and these weak planes are the main factors affecting the mechanical strength of coal rock. In order to quantitatively study the mechanism, rock samples were soaked in three kinds...

..., is utilized for estimating the maximum horizontal stress magnitude. Breakout tip strength is evaluated by considering several mechanisms perceived to be responsible for breakout stabilization. The maximum horizontal stress magnitude is then estimated from the equilibrium condition of stress and rock strength...

... Abstract Rock core samples may be tested by destructive methods to determine the material’s mechanical strength. These measurements may however introduce further uncertainties, which often evolve around how to apply the laboratory derived data to subsurface conditions. Indeed, strength...

... period. The primary cause of wellbore instability is the accumulation of plastic damage induced by shear or compressive stress around the wellbore. 1. INTRODUCTION Wellbore instability is a classic rock mechanics problem, it is generally caused by excessive stress concentration that exceeds rock strength...
