Natural gas resources are classified as conventional or unconventional depending on the geological drivers significant for occurrence and intensive technology necessary for exploitation. There is growing interest in exploiting unconventional shale gas across the globe to keep robust portfolio and chase long term opportunities. Shale gas reservoirs have long been recognized, meanwhile, they have been regarded as source rocks for conventional Previous HitpetroleumNext Hit systems. Gas shale that has not entirely expelled its gas potential is self-contained Previous HitpetroleumNext Hit Previous HitsystemNext Hit, in other words, in-situ gas generation, migration and trapping. Whether gas is present in shale depends on multi-factors like anoxic depositional environment and pressure/temperature history to become excellent potential source rocks with high quality organic matter, gas content, porosity and permeability. There are many characteristics in common to the points, whatever is excellent source rock in conventional Previous HitpetroleumNext Hit Previous HitsystemNext Hit or reservoir in unconventional Previous HitpetroleumNext Hit Previous HitsystemNext Hit. However, successful fracturing of the material for gas production also depends on rock mineralogy, mechanical stratigraphy distribution, regional stress field that controls on the extent to which this potential can be realized.

The presentation will look over basin's hydrocarbon potential through time and space and provide essential critical elements and process picture of Silurian hot shale Previous HitpetroleumNext Hit Previous HitsystemNext Hit to express extensive variables and response to multi-stages tectonic events affecting the Silurian shale deposition region in Sichuan stacked basin and surroundings, compared to those of other regions outside China. In conclusion, it’s not only technology play, but integrated Previous HitpetroleumNext Hit Previous HitsystemTop with conventional and unconventional oil and gas resource.
