An investigation on the effect of thermal maturity and rock composition on the mechanical behavior of carbonaceous shale formations

An accurate assessment of the geomechanical behavior of shale reservoirs is extremely significant in screening the potential intervals for hydraulic stimulation and sweet spot mapping. While most of the studies were carried out on siliciclastic shales, we here examine the mechanical behavior of a carbonaceous organic-rich shale in the Lurestan Basin, Iran, and the factors controlling them. Direct laboratory measurements at reservoir stress...
