In recent years, China has made significant progress in exploring oil and gas in sandstone
and carbonate rocks with burial depths of more than 6000 m in the Tarim, Sichuan, and …

Gas production from the Barnett Shale relies on hydraulic fracture stimulation. Natural
opening-mode fractures reactivate during stimulation and enhance efficiency by widening …

An accessible resource, covering the fundamentals of carbonate reservoir engineering
Includes discussions on how, where and why carbonate are formed, plus reviews of basic …

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 …

Using examples from core studies, this article shows that separate identification of
mechanical stratigraphy and fracture stratigraphy leads to a clearer understanding of …

Well-developed natural fractures in the tight gas conglomerate reservoirs of the
northwestern Sichuan Basin, China, are proved to greatly contribute to the porosity and …

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

Fracture intensity, the number of fractures per unit length along a sample line, is an
important attribute of fracture systems that can be problematic to establish in the subsurface …

Natural fractures are effective reservoir spaces and the main seepage channel for tight
sandstones, which control the migration, enrichment, and productivity of oil and natural gas …

For one essential ingredient of permeable fracture networks (degree of fracture pore-space
preservation in large fractures), I show how the characterization challenge presented by …
