A New Geochemical Tool for the Assessment of Organic-Rich Shales

Unconventional Resources Technology Conference, Denver, Colorado, 12-14 August 2013, 2013
Summary Here we present a recently developed pyrolysis technique called LIPS (Laser Induced Pyrolysis System) that can be used for a high-resolution definition of total organic carbon (TOC) contents in core samples. Typically, LIPS measurements are performed on a centimeter scale, and hence, the syste m collects roughly 10,000 TOC values on a 100 meter

Apparent gas permeability in an organic-rich shale reservoir

Fuel, 2016
Abstract 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

Stress-dependent permeability of organic-rich shale reservoirs: Impacts of stress changes and matrix shrinkage

Journal of Petroleum Science and Engineering, 2019
Effective stress is gradually increased and permeability is gradually reduced during reservoir depletion caused by hydrocarbon production, while the organic-rich matrix might experience a shrinkage process that will boost the permeability.

Estimating thermal maturity of organic-rich shale from well logs: Case studies of two shale plays

Fuel, 2019
Thermal maturity is an important geochemical parameter for the study of source rocks in unconventional shale plays. Using well logs to estimate thermal maturity would overcome the discontinuity of core sample analysis and can provide continuous profiles.

Core and Petrographic Sequential Analysis of Organic-Rich Shale

Proceedings, 2014
In 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, 2016
Abstract 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.

Hydrocarbon saturation in a Lower-Paleozoic organic-rich shale gas formation based on Markov-chain Monte Carlo stochastic inversion of broadband electromagnetic dispersion logs

Fuel, 2019
An organic-rich shale gas formation generally exhibits high clay content, high total organic carbon (TOC), low porosity, high tortuosity, and the presence of conductive pyrite that adversely affect the well-log-derived hydrocarbon saturation estimations.

Experimental study of swelling of organic rich shale in methane

International Journal of Coal Geology, 2015
Abstract Gas is stored in shale mainly in free and adsorbed phases. Since a significant amount of gas in the shale is adsorbed to the organic matter and/or clay minerals, it is possible that gas adsorption will induce shale swelling, which may then has an impact on the gas flow behavior in the shale thus its gas production.
