Permeability Measurement of Tight Rock
Description
This open access book primarily focuses on the methodologies for measuring the permeability of tight rock formations. Permeability stands as a pivotal parameter in assessing the permeability or transport capacity of tight reservoirs, exerting a significant influence on the extraction of reservoir resources. Laboratory experiments on permeability serve as a crucial means to understand the intrinsic permeability of shale. However, the permeability of shale is exceedingly low and is susceptible to influences from various experimental factors such as gas adsorption, ambient temperature, and testing apparatus. The precise measurement of shale permeability remains one of the challenges that perplex researchers and designers. This book aims to address the following key issues: permeability measurement methods that take into account the effects of adsorption, and the measurement of anisotropic permeability in rocks.
