Some key technical issues in modelling of gas transport process in shales: a review

摘要: As a result of small pore sizes and property heterogeneities at different scales, flow processes the related physical mechanisms in shales can be dramatically from those conventional gas reservoirs. To accurately capture “unconventional” transport requires reevaluation dominant physics controlling shales, as well innovative hardware technologies to estimate critical material properties. do so, we need quantify current knowledge identify technology gaps especially modeling fluid shale While includes many important aspects, this paper focuses on complex heterogeneous matrix. It discusses recent progress areas multi-scale flow, fracturing imbibition, stress-dependent matrix Future research topics are also suggested based identified gaps.
