This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid flow behavior through ultra-tight shale matrices is still poorly understood. Applications of classical concepts to these unconventional materials are proving to be insufficient and there is a need to generate data on the fundamental processes of fluid transport through nano-porosity networks. This work attempts to address this issue through an array of flow and materials characterization experiments. The context of this integrated petrophysical analysis is the examination of the impact of fluid leakoff and post stimulation shut-in or "soaking time" on effective gas permeability. Past research on fluid leakoff and soaking time has been predominantly conducted with relatively high permeability rocks and for short durations of up to 15 days. We present data on shales with nano-Darcy (10-6 md) permeability and have run experiments for up to 30 days. A pulse-decay permeability apparatus has been custom designed to accurately measure gas permeabilities down to 1nD and the results have been scrutinized in conjunction with X-Ray CT, SEM imaging, Mercury Porosimetry and XRD analysis. Results indicate that laminations and micro-fractures play an important role in fluid transport properties in these ultra-tight shales. There appears to be very little connected porosity at scales longer than a few millimeters, making clastic permeability virtually non-existent. The consequences of fluid leakoff are severe and the introduction of relatively small quantities of liquid into the rock matrix leads to orders of magnitude reductions in effective permeability. The impact of this leakoff fluid then evolves significantly as it is spontaneously redistributed through the rock matrix due to capillary imbibition. Base permeability or the initial absolute (single phase) permeability of dry sample is found to be key to understanding the consequences of soaking time -- high permeability samples experience relatively minor permeability impairment due to leakoff and permeability recovery with soaking time while tighter samples experience permeability damage greater than 90% due to leakoff which continues to decline with soaking time. This raises the strong possibility that the practice of soaking in shale gas wells may be detrimental to long term production and ultimate recovery.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on developing an improved understanding of fluid flow in gas shales. The problem is studied at multiple scales, and using a variety of approaches spanning several disciplines. In Chapter 2, Adsorption of Methane and Carbon Dioxide on Gas Shale and Pure Mineral Samples, we present measurements of methane and carbon dioxide adsorption isotherms at 40°C on gas shale samples from the Barnett, Eagle Ford, Marcellus and Montney reservoirs. Carbon dioxide isotherms were included to assess its potential for preferential adsorption, with implications for its use as a fracturing fluid and/or storage in depleted shale reservoirs. To better understand how the individual mineral constituents that comprise shales contribute to adsorption, measurements were made on samples of pure carbon, illite and kaolinite as well. The resultant volumetric swelling strain was also measured as a function of pressure/adsorption. In Chapter 3, Experimental Investigation of Matrix Permeability of Gas Shales, we present laboratory experiments examining the effects of confining stress and pore pressure on permeability. Experiments were carried out on intact core samples from the Barnett, Eagle Ford, Marcellus and Montney shale reservoirs. The methodology we used to measure permeability allows us to separate the reduction of permeability with depletion (due to the resultant increase in effective confining stress) and the increase in permeability associated with Knudsen diffusion and molecular slippage (also known as Klinkenberg) effects at very low pore pressure. By separating these effects, we are able to estimate the relative contribution of both Darcy and diffusive fluxes to total flow in depleted reservoirs. Our data show that the effective permeability of the rock is significantly enhanced at very low pore pressures (

Available in PDF, EPUB and Kindle. Book excerpt: The need for energy is increasing and but the production from conventional reservoirs is declining quickly. This requires an economically and technically feasible source of energy for the coming years. Among some alternative future energy solutions, the most reasonable source is from unconventional reservoirs. As the name “unconventional” implies, different and challenging approaches are required to characterize and develop these resources. This Special Issue covers some of the technical challenges for developing unconventional energy sources from shale gas/oil, tight gas sand, and coalbed methane.

This book was released on 2017-10-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A surge of interest in the geomechanical and petrophysical properties of mudrocks (shales) has taken place in recent years following the development of a shale gas industry in the United States and elsewhere, and with the prospect of similar developments in the UK. Also, these rocks are of particular importance in excavation and construction geotechnics and other rock engineering applications, such as underground natural gas storage, carbon dioxide disposal and radioactive waste storage. They may greatly influence the stability of natural and engineered slopes. Mudrocks, which make up almost three-quarters of all the sedimentary rocks on Earth, therefore impact on many areas of applied geoscience. This volume focuses on the mechanical behaviour and various physical properties of mudrocks. The 15 chapters are grouped into three themes: (i) physical properties such as porosity, permeability, fluid flow through cracks, strength and geotechnical behaviour; (ii) mineralogy and microstructure, which control geomechanical behaviour; and (iii) fracture, both in laboratory studies and in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Mitigation and prevention of shale-formation damage caused by hydraulic-fracturing fluid/rock interactions play an important role in well-production stability and subsequent refracturing design. This study presents three experimental investigations on the interaction of water/shale, fluid/clay, and fluid/shale. A series of experiments were designed to investigate fluid/shale interactions: hydrophilic to hydrophobic alteration through chemical-vapor deposition, nanoindentation testing on shale sample, geotechnical laboratory experiments on contaminated clay, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and scanning electron microscope (SEM) on shale sample. A clay-matrix-based data-screening criterion is proposed for nanoindentation. The continuous-stiffness-measurment (CSM) method is proved to have better definition and characterization of softening of shale based on the proposed criterion. This study furthered the numerical model of clay deformation by Hattab and Chang (2015) by considering different pore fluid concentration. The fracturing fluid contaminated clay produced changes of geotechnical properties. Based on the proposed criterion and designed experiments, fracturing fluid contaminated shale was observed to gain 4 to 6% of NaCl. However, all other minerals contents are found to decrease after the shale powder-fluid interaction. A characteristic depth was proposed to consider reduction of hardness and mineral content at the same time. Moreover, an empirical equation was proposed to describe fracture toughness of shale by using a selection of indentation depth, its corresponding hardness and Young's modulus.

This book was released on 2020-08-27 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of naturally fractured reservoirs, especially shale gas and tight oil reservoirs, exploded in recent years due to advanced drilling and fracturing techniques. However, complex fracture geometries such as irregular fracture networks and non-planar fractures are often generated, especially in the presence of natural fractures. Accurate modelling of production from reservoirs with such geometries is challenging. Therefore, Embedded Discrete Fracture Modeling and Application in Reservoir Simulation demonstrates how production from reservoirs with complex fracture geometries can be modelled efficiently and effectively. This volume presents a conventional numerical model to handle simple and complex fractures using local grid refinement (LGR) and unstructured gridding. Moreover, it introduces an Embedded Discrete Fracture Model (EDFM) to efficiently deal with complex fractures by dividing the fractures into segments using matrix cell boundaries and creating non-neighboring connections (NNCs). A basic EDFM approach using Cartesian grids and advanced EDFM approach using Corner point and unstructured grids will be covered. Embedded Discrete Fracture Modeling and Application in Reservoir Simulation is an essential reference for anyone interested in performing reservoir simulation of conventional and unconventional fractured reservoirs. Highlights the current state-of-the-art in reservoir simulation of unconventional reservoirs Offers understanding of the impacts of key reservoir properties and complex fractures on well performance Provides case studies to show how to use the EDFM method for different needs
