Geophysical well-log evaluation in the era of unconventional hydrocarbon resources (mainly
tight oil and gas, shale oil and gas) is complicated and challenging. This review aims to fill …

Geophysical well logs are widely used in geological fields, however, there are considerable
incompatibilities existing in solving geological issues using well log data. This review …

Geophysical well log data are widely used in the field of structural geology, sedimentary
geology and petroleum geology. Gaps and misunderstandings are still existing in the …

Lamellation fractures, as important reservoir space and fluid flow channels, have significant
effects on reservoir quality and hydraulic fracturing engineering in shale oil reservoirs. Core …

Breakthroughs in shale gas exploration and production technology in China point to a
possible solution to Pakistan's current energy crises. In this study, we evaluate the shale gas …

Source rocks are fundamental elements for petroleum systems, and Total Organic Carbon
(TOC) is one of the most important geochemical parameters in source rock property …

Initial stress is widely observed in porous materials. However, its constitutive theory remains
unknown due to the lack of a framework for modeling the interactions between initial stress …

Brittleness is a significant mechanical property which determines the degree of fracturing
difficulty in shale gas exploitation and hence, the brittleness index (BI) is a key parameter for …

Shale gas reservoirs are generally exploited through horizontal drilling and hydraulic
fracturing. Petrophysical and geomechanical parameters help to determine horizontal well …
