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.

Oxidative dissolution kinetics of organic-rich shale by hydrogen peroxide (H2O2) and its positive effects on improving fracture conductivity

, 2021
Maintaining the fracture network created by hydraulic fracturing remains challenging because unpropped fractures close during production, resulting in shale gas production decline.

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.

Impact of tectonism on pore type and pore structure evolution in organic-rich shale: Implications for gas storage and migration pathways in naturally deformed rocks

Fuel, 2018
Tectonism significantly affects the pore type and pore structure evolution of organic-rich shale. The Lower Cambrian Lujiaping Shale in the northeastern of the upper Yangtze area is a significant marine shale being studied for shale gas exploration in ...

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.

Productivity or preservation? The factors controlling the organic matter accumulation in the late Katian through Hirnantian Wufeng organic-rich shale, South China

Marine and Petroleum Geology, 2019
The Wufeng organic-rich shale is widespread in the Upper Yangtze platform, and it is one of the most advantageous shale gas producers in China. Its deposition commenced with the onset of the Boda warming event in the late Katian and terminated at the ...
