The Cambay basin of Western India has been proved as the most prominent and promising basin for major shale oil and gas discoveries. The present work is an exploration study of shales of different tectonic blocks of Cambay basin, which characterizes it as potential source as well as a reservoir for hydrocarbon generation and expulsion. Major experimental work was done on the Cambay shale of North tectonic block of Cambay basin and it was found that the shale has good to excellent organic richness, hybrid oil/gas bearing potential, mature shale potential, good hydrocarbon generation potential and good kerogen transformation. On the contrary, shales of south tectonic block are at the immature phase of hydrocarbon generation and may generate hydrocarbons upon thermal maturation and deep burial. The performed analysis and interpretation are explaining the true hydrocarbon potential of shales of Cambay basin and hence providing with a roadmap for the shale geochemical characterization which may be useful for development of shale plays at large scale.

印度西部的坎贝盆地已被证明是主要页岩油气发现最突出，最有前途的盆地。目前的工作是对坎贝盆地不同构造区块的页岩进行的勘探研究，其特征是它是潜在的烃源以及油气生成和驱出的储层。在坎贝盆地北部构造块的坎贝页岩上进行了重大实验工作，发现该页岩具有良好的有机质富集性，混合油气的潜力，成熟的页岩潜力，良好的生烃潜力和良好的干酪根转化作用。相反，南部构造块体的页岩处于生烃的未成熟阶段，可能在热成熟和深埋时产生烃。
