Fracturing of organic-rich shale during heating

Proceedings of the 11th SEGJ International Symposium, Yokohama, Japan, 18-21 November 2013, 2013
Organic-rich shales, traditionally considered as source rocks, have recently become an ambitious goal for oil and gas industry as important unconventional reservoirs. Understanding of initiation and development of fractures in organic-rich shales is crucially important as they drastically increase permeability of these low permeable shales.

Nanopore structure characterization for organic-rich shale using the non-local-density functional theory by a combination of N2 and CO2 adsorption

Microporous and Mesoporous Materials, 2016
Low-pressure gas adsorption is widely used for pore size analysis of porous materials, and has been employed to characterize pore systems in shale. However, the complexity of shale pore structures means that different methods and models may lead to ...

Permeability of Organic-Rich Shale

SPE Journal, 2014
Summary Measured permeability of an organic-rich shale sample varies significantly with applied laboratory conditions, such as the confining pressure, temperature, and the measurement fluid type. This indicates that the measured quantity is influenced by several mechanisms that add complexity to the measurement.

Maturity and Impedance Analysis of Organic-Rich Shales

SPE Reservoir Evaluation & Engineering, 2009
Summary Organic-rich shales (ORSs) need to be studied in detail to understand the provenance and the generation of hydrocarbons from source rocks. In recent years, ORSs have gained importance as hydrocarbon resources as well. Successful exploration and production programs for ORSs need reliable identification of their kerogen content as ...

Deformation structures in organic-rich shales

AAPG Bulletin, 2011
Abstract Seismic images of Upper Jurassic organic-rich siliciclastic rocks are studied along the 2000-km (1243-mi) Norwegian margin. These rocks are considered the main source rock for most of the large oil and gas fields in the North Sea and Norwegian Sea.

The Impact of Shale Preservation on the Petrophysical Properties of Organic-Rich Shales

SPE Annual Technical Conference and Exhibition, 2013
Abstract The procedure to evaluate the basic petrophysical properties of hydrocarbon bearing shales varies substantially in the oil and gas industry, making it difficult to compare experimental results across labs. In this paper, we present a methodology that we hope will become an industry standard for preserving and preparing shales ...

Carbon Dioxide Storage Capacity of Organic-rich Shales

SPE Annual Technical Conference and Exhibition, 2010
Abstract This paper presents an experimental study on the ability of Barnett shale core samples to store carbon dioxide. An apparatus has been built for psrecise measurements of gas pressure and volumes at constant temperature. A new analytical methodology is developed allowing interpretation of the pressure-volume data in terms of ...

Mapping of Microbial Habitats in Organic-Rich Shale

Proceedings of the 3rd Unconventional Resources Technology Conference, 2015
Summary Microbial communities within unconventional hydrocarbon reservoirs in the oil to wet gas window are known to be present but sparse and believed also to be almost entirely dormant, due to heat, lack of space, and near-equilibrium redox conditions at the microscale – conditions that change when a rock is hydraulically fractured.

Characterization of anisotropy in the permeability of organic-rich shales

Journal of Petroleum Science and Engineering, 2015
Abstract Accurate determination of permeability is essential and challenging in organic-rich shales due to the tight and heterogeneous nature of shale formations, the presence of lamination as well as induced or natural fractures and the sensitivity of fracture permeability to stress.

The Effect of High Power Laser on Organic-Rich Shales

SPE Middle East Oil & Gas Show and Conference, 2021
Abstract The objective of this work is to characterize the effect of a high power laser (HPL) on organic-rich shales. The analysis combines machine learning with advanced characterizations to reveal the geochemical and mechanical transformations induced by high power laser in source rocks.
