[1] Rock physics attempts to relate the geophysical response of a rock to geologic properties of interest, such as porosity, lithology, and fluid content. The geophysical properties estimated by field-scale surveys, however, are impacted by additional factors, such as complex averaging of heterogeneity at the scale of the survey and artifacts introduced through data inversion, that are not addr...

Understanding how geophysical and hydrologic properties are related is a key problem in hydrogeophysical data fusion. Traditionally this link has been made by rock physics investigations that define how pore-scale variations in properties like mineralogy, fluid content, and grain geometry affect the geophysical response of a rock or sediment. As the scale of investigation increases from the lab...

By examining wireline data from Woodford and Wolfcamp gas shale, we find that the primary controls on elastic-wave velocity are total porosity, kerogen content, mineralogy. At a fixed both V p s strongly depend clay as well content. Both velocities also strong functions of sum above two components. Even better discrimination elastic properties at porosity is attained if use solid matrix (includ...

Abstract The development and stimulation of oil gas fields are inseparable from the experimental analysis reservoir rocks. Large number experiments, poor properties thin thickness will lead to insufficient cores, which restricts evaluation effect cores. Digital rock physics (DRP) can solve these problems well. This paper presents a rapid, simple, practical method establish pore structure lithol...
