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 …

The feldspar group is one of the most common types of minerals in the earth's crust.
Feldspar alteration (including the whole processes of feldspar dissolution, transfer of …

An integrated nomenclature scheme is proposed to capture the inherent heterogeneity of
fine-grained sedimentary rocks at the 102 to 10− 3 mm scale and to assist the evaluation of …

Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

This study aims to determine the interdependence of deposition, tectonics and diagenesis in
a prolific hydrocarbon reservoir. This has been achieved through an integrated field study …

Primary sedimentary composition of shales and subsequent diagenetic modifications are
key factors in controlling the pore development and preservation in shale gas reservoirs …

Organic rich shales in coal-bearing strata deposited from marine to lacustrine environments
are well developed in China. The Paleozoic coal-bearing shales have been significantly …

Mineral types (detrital and authigenic) and organic-matter components of the Ordovician-
Silurian Wufeng and Longmaxi Shale (siliceous, silty, argillaceous, and calcareous/dolomitic …

Abstract The Sichuan Basin is a major target for shale gas exploration in present China
because of its rich gas stored in abundant black shales with multiple bed series. For further …

Lithologic heterogeneity of the Eagle Ford Formation in South Texas arises from mixing of
extrabasinal grains of siliciclastic composition with intrabasinal grain assemblages …
