MICROSTRUCTURE AND MICROMECHANICS OF SHALE ROCKS: CASE STUDY OF MARCELLUS SHALE

Facta Universitatis, Series: Mechanical Engineering, 2017
Shale rocks play an essential role in petroleum exploration and production because they can occur either as source rocks or caprocks depending on their mineralogical composition and microstructures. More than 60% of effective seals for geologic hydrocarbon bearing formations as natural hydraulic barriers constitute of shale caprocks.

Numerical Simulation Based on the Canister Test for Shale Gas Content Calculation

Energies, 2021
The accurate determination of the gas in place in shale reservoirs is a basic but challenging issue for shale gas evaluation. Conventional canister gas desorption tests on retrieved core samples and subsequent data analyses (via linear or polynomial ...

Experimental Study on the Stress Sensitivity and Influence Factors of Shale under Varying Stress

Shock and Vibration, 2018
Shale reservoirs are characterized by extremely low permeability and high clay content. To further study the stress sensitivity of a shale reservoir, the Lower Cambrian shale in north Guizhou was utilized.

Digital Rock Physics Application in Determining The Porosity of Shale Rock

Journal of Physics: Conference Series, 2022
Abstract This research is focusing on determining the porosity of shale rock using the Digital Rock Physics (DRP) method. The DRP method uses fiji software to process μCT-scan data of shale coreplug through segmentation and thresholding processes to determine the pores of the rock and then to determine the value of rock porosity.

The influence of pyrolysis type on shale oil generation and its composition (upper layer of Aleksinac oil shale, Serbia) [PDF]

Journal of the Serbian Chemical Society, 2017
The influence of pyrolysis type on the shale oil generation and its composition was studied. Different methods such as Rock-Eval pyrolysis, thermogravimetric analysis (TGA) and pyrolysis in the open and closed systems were applied. Samples from the Upper

A Study of Nonlinear Elasticity Effects on Permeability of Stress Sensitive Shale Rocks Using an Improved Coupled Flow and Geomechanics Model: A Case Study of the Longmaxi Shale in China

Energies, 2018
Gas transport in shale gas reservoirs is largely affected by rock properties such as permeability. These properties are often sensitive to the in-situ stress state changes. Accurate modeling of shale gas transport in shale reservoir rocks considering the

INFLUENCE OF SWELLING ON SHEAR STRENGTH OF SHALE-LIMESTONE INTERFACE

Rudarsko-geološko-naftni Zbornik, 2022
Rock slope stability is almost controlled by the behaviour of the interface between rock layers. The presence of shale layers between limestone layers complicates this behaviour.

Rock Physics, Geomechanics and Rock Properties in Shales — Where are the Links? [PDF]

Proceedings of the First Southern Hemisphere International Rock Mechanics Symposium, 2008
Understanding shale behaviour is of increasing importance to the petroleum industry and also impacts on engineering issues such as landslides and hazardous waste disposal. Few data are currently available regarding geomechanical, petrophysical and dynamic elastic properties of shales that have been properly preserved and tested under controlled pore ...

Experimental study on initiation and propagation of hydraulic fractures in stratified shale oil reservoirs

Journal of Petroleum Exploration and Production Technology
The bedding planes of the Gulong shale oil reservoir in Daqing, China are extremely developed, which causes the hydraulic fractures to extend excessively in the horizontal direction while their longitudinal propagation is limited. In order to improve the
