Modeling of Biot’s coefficient for a clay-bearing sandstone reservoir

The exploration of unconventional reservoirs has been vigorously developed with the application of hydraulic fracturing technology in horizontal wells. The success of fracturing depends on the accuracy of the effective stress, which could be considerably influenced by Biot’s coefficient. Biot’s coefficient is mainly influenced by the clay content, porosity, and fluid saturation. Previous studies regarding the calculation of Biot’s coefficient...
