Methane Adsorption Capacity of Marine-Continental Transitional Facies Shales: The Case Study of the Upper Permian Longtan Formation, Northern Guizhou Province, Southwest China

Journal of Petroleum Science and Engineering, 2019
Abstract Factors influencing the methane adsorption capacity (MAC) of marine-continental transitional facies shales have been identified applying a variety of techniques (e.g., total organic carbon (TOC) content, X-ray diffraction mineralogy, low-pressure CO2 and N2 adsorption, and methane adsorption analyses) on samples from the Upper Permian ...

Developmental characteristics and dominant factors of fractures in marine–continental transitional facies tight sandstone reservoirs in heavily deformed areas: a case study

Arabian Journal of Geosciences, 2020
Fractures enhance secondary porosity and permeability of tight sandstone and in turn promote fluid migration and well recovery. The developmental characteristics and dominant factors of tight sandstone reservoir fractures in the lower Permian Shanxi Formation, southern Qinshui Basin, were systematically studied by combining qualitative observations ...

Role of Overlying and Underlying Limestones in the Hydraulic Fracturing of Shale Sections: The Case of Marine-Continental Transitional Facies in the Southern North China Basin

2021
A few limestone layers usually underlie and or or overlie the shale layers/sections in marine facies, especially in marine-continental transitional facies (MCTF). The role of limestones in the hydraulic fracturing of shale sections will help in selecting the fracturing location, improving the stimulation power, and clarifying induced-fracture ...

Analysis of the Geological Conditions for Shale Gas Accumulation: Two Different Carboniferous Marine-Continental Transitional Facies in the Bayanhot Basin, China

Energy & Fuels, 2017
The sedimentary environment plays an important role in the enrichment of shale gas resources. In this paper, the characteristics of the marine-continental transitional sedimentary environments in the Bayanhot Basin are studied via laboratory analysis, scanning electron microscopy, and comparative analyses of field data.
