Natural fractures have long been suspected as a factor in production from shale reservoirs
because gas and oil production commonly exceeds the rates expected from low-porosity …

Fracture pattern development has been a challenging area of research in the Earth sciences
for more than 100 years. Much has been learned about the spatial and temporal complexity …

Abstract Deep shale gas reservoir (3,500∼ 4,500 m) of Wufeng–Longmaxi Formation in
southern Sichuan Basin in China has great potential for exploration and development, with …

Microfractures are small, high-aspect-ratio cracks in rock that result from application of
differential stresses. Although the term has been used to refer to larger features in the …

We propose a review to discuss the large number of studies dealing with the fluid history in
extensional and compressional sedimentary basins that evolved along the Iberian-Eurasian …

Salt tectonics is the study of how and why salt structures evolve and the three-dimensional
forms that result. A fascinating branch of geology in itself, salt tectonics is also vitally …

Accurate predictions of natural fracture flow attributes in sandstones require an
understanding of the underlying mechanisms responsible for fracture growth and aperture …

Reservoir-quality predictive models will be a useful element of risk analysis until remote-
sensing tools are invented that accurately measure effective porosity and permeability …

Using examples of regional opening-mode fractures in sandstones from the Cambrian
Flathead Formation, Wyoming, we show that quartz deposits preferentially fill fractures up to …

Tight gas reservoirs are notoriously difficult to characterize; routine methods developed for
conventional reservoirs are not appropriate for tight gas reservoirs. In this article, we …
