Apparent gas permeability in an organic-rich shale reservoir
Fuel, 2016Abstract Accurate models of gas transport in shale gas reservoirs must consider complex gas transport mechanisms and phase behavior in nanopores, as well as different pore types. The gas transport mechanisms in shale gas reservoirs include viscous flow, Knudsen diffusion, surface diffusion, adsorption and desorption. In this study, a unified model of

Core and Petrographic Sequential Analysis of Organic-Rich Shale
Proceedings, 2014In this work, different samples from the unconventional gas-producing Barnett Shale, Fort worth Basin, Texas, USA have been subjected to a variety of sequential petrographic analysis techniques. The primary goal of this work is to develop best analysis procedures for such type of organic-rich shale, since size and color are of little help.

Analytical Solution of Matrix Permeability of Organic-Rich Shale
International Petroleum Technology Conference, 2016Abstract Apparent matrix permeability of organic-rich shale is complicated because of its unique pore structure, gas storage and transport mechanisms. In inorganic pores, free gas is the only phase considered. While in organic pores, adsorbed phase coexists with free gas. Surface diffusion is the transport mechanism of the adsorbed phase.

Microporoelastic modeling of organic-rich shales
2015Due to their abundance, organic-rich shales are playing a critical role in re-defining the world's energy landscape leading to shifts in global geopolitics. However, technical challenges and environmental concerns continue to contribute to the slow growth of organic-rich shale exploration and exploitation worldwide.

The effect of kerogen on the AVO response of organic-rich shales
SEG Technical Program Expanded Abstracts 2013, 2013Shales make up a large proportion of the rocks in most sedimentary basins and form the seal and source rocks for many hydrocarbon reservoirs. In unconventional shale plays, shale acts as both the source rock and the reservoir. Currently, there is great interest in organic-rich shales because they represent an enormous energy resource.

The effect of kerogen on the elastic anisotropy of organic-rich shales
Geophysics, 2013ABSTRACT The elastic properties of reservoir rocks are important for geomechanics applications; the most important of which are: analysis of stress changes due to production, analysis of rock deformation and failure, wellbore trajectory optimization, and the design of hydraulic fractures.

Impact of faulting on organic-rich shale reservoir structure
As a key parameter affecting shale gas accumulation, the physical characteristics of shale reservoir are greatly affected by tectonic stress transformation and deformation, which not only affects the occurrence state of shale gas, but also determines the evaluation and exploration prospect of shale gas resource potential by changing the migration and ...Xiaoshi Li +3 more
