Lithofacies Paleogeography and Geological Survey of Shale Gas [PDF]
This is an open access book. This book presents new theory and methods on compiling lithofacies paleogeographic maps as a key tool for guiding geological survey on shale gas. The fundamental goal of the shale gas geological survey is to find the ‘dessert’

Quantifying the anisotropy and tortuosity of permeable pathways in clay-rich mudstones using models based on X-ray tomography [PDF]
, 2017 The permeability of shales is important, because it controls where oil and gas resources can migrate to and where in the Earth hydrocarbons are ultimately stored.

Shale lithofacies and reservoir space of the Wufeng–Longmaxi Formation, Sichuan Basin, China
Petroleum Exploration and Development, 2012 Based on observation of the outcrops and cores of the Late Ordovician to the Early Silurian Wufeng-Longmaxi shale, developed in the deep water shelf environment, in the southeast of the Sichuan Basin, the mineralogical features, lithofacies characteristics and reservoir space types were studied and the factors affecting reservoir capacity were analyzed

CHARACTERIZATION OF PORE STRUCTURES ON THE LOWER SILURIAN MARINE SHALE GAS PLAY [PDF]
, 2016 Gas shales are different from conventional reservoir as the strata are both source rock and reservoir rock for gas, and no structural or stratigraphic traps are needed to retain the gas. The recent advances in horizontal drilling and hydraulic fracturing

The splicing of backscattered scanning electron microscopy method used on evaluation of microscopic pore characteristics in shale sample and compared with results from other methods [PDF]
, 2018 The splicing of backscattered scanning electron microscopy (SB-SEM) method was applied to evaluate the microscopic pore characteristics of the Lower Silurian Longmaxi Shale samples from Py1 well in Southeast Chongqing, China.
