Book Description :

Unconventional shale gas reservoirs are over-mature potential source rocks and possess commercial quantities of hydrocarbons in a mechanism which is different from conventional gas reservoirs. These organically rich shale rocks also known as continuous hydrocarbon reservoirs represent a voluminous, long-term, global source of thermo-genic methane and other hydrocarbon gases and could be referred to as shale gas. Roseneath and Murteree shale formations in Cooper Basin have been identified as potential shale gas reservoirs in South Australia. Core samples from these carbonaceous shales were selected for this study. Petrophysical and mineralogical characterization of shale gas reservoirs is still a challenge due to ultra-fine grained micro-fabric, micro level heterogeneity and anisotropic characteristics of these sedimentary rocks. Unlike conventional gas reservoirs, shale gas reservoirs have very low effective porosity and micro to nano-scale permeability. Conventional standards applications to characterize unconventional gas reservoirs give contradictory results about the mineralogy and rock characteristics, effective and total porosity as well as estimated brine saturation. These uncertainties in the results raised the question, which tools/standards are suitable for petrophysical and mineralogical evaluation of shale gas reservoir. This research outcome tried to answer the above questions and tells how mineralogy and rock characterization, total porosity, reasons of very low effective porosity and saturation which play a key role in selection and development of a shale gas play, can be evaluated and estimated using both conventional and unconventional techniques. The Roseneath and Murteree shale formations in Cooper Basin have been identified as potential shale gas reservoirs in South Australia. Two core samples from these carbonaceous shales intercepted in Della4 and Moomba46 wells were selected for this project. Core samples were used for number of reservoir characterization phases namely, a) minerals quantification and rock classification, b) visual identification and density of pores location in grains and matrix, c) their types, size classification and interconnectivity, d) evaluation of effective and total interstitial/intergranular and intragranular porosity. While log data from Della# 4 was applied in various resistivity models for water saturation estimation in Murteree shale.

Book Description :

Since the beginning of the US shale gas revolution in 2005, the development of unconventional oil and gas resources has gathered tremendous pace around the world. This book provides a comprehensive overview of the key geologic, geophysical, and engineering principles that govern the development of unconventional reservoirs. The book begins with a detailed characterization of unconventional reservoir rocks: their composition and microstructure, mechanical properties, and the processes controlling fault slip and fluid flow. A discussion of geomechanical principles follows, including the state of stress, pore pressure, and the importance of fractures and faults. After reviewing the fundamentals of horizontal drilling, multi-stage hydraulic fracturing, and stimulation of slip on pre-existing faults, the key factors impacting hydrocarbon production are explored. The final chapters cover environmental impacts and how to mitigate hazards associated with induced seismicity. This text provides an essential overview for students, researchers, and industry professionals interested in unconventional reservoirs.

Book Description :

The ever increasing energy demand brings about widespread interest to rapidly, profitably and efficiently develop unconventional resources, among which tight gas sands hold a significant portion. However, optimization of development strategies in tight gas fields is challenging, not only because of the wide range of depositional environments and large variability in reservoir properties, but also because the evaluation often has to deal with a multitude of wells, limited reservoir information, and time and budget constraints. Unfortunately, classical full-scale reservoir evaluation cannot be routinely employed by small- to medium-sized operators, given its timeconsuming and expensive nature. In addition, the full-scale evaluation is generally built on deterministic principles and produces a single realization of the reservoir, despite the significant uncertainty faced by operators. This work addresses the need for rapid and cost-efficient technologies to help operators determine optimal well spacing in highly uncertain and risky unconventional gas reservoirs. To achieve the research objectives, an integrated reservoir and decision modeling tool that fully incorporates uncertainty was developed. Monte Carlo simulation was used with a fast, approximate reservoir simulation model to match and predict production performance in unconventional gas reservoirs. Simulation results were then fit with decline curves to enable direct integration of the reservoir model into a Bayesian decision model. These integrated tools were applied to the tight gas assets of Unconventional Gas Resources Inc. in the Berland River area, Alberta, Canada.

Book Description :

The increasing demand in energy has strengthen the dependence on fossil fuels. On the other hand, the conventional hydrocarbon reservoirs are depleting rather quickly which prompted an important study of the hydrocarbon reservoirs from unconventional reservoirs. Over the last two decades, the improvement in technology and recovery methods has allowed the industry to extract hydrocarbon from unconventional reservoirs. There are been important advancements in drilling and reservoir engineering technologies.In order to overcome some of the costs associated with the exploitation of those reservoirs, an extensive use of techniques such as directional drilling to has been largely recommended and has proven to be more efficient. Directional drilling allows to control the direction of the wellbore to increase the contact with the target or pay zone location among other significant benefits.Reservoir simulation refers to constructing computer models to gain a better understanding of reservoirs. It is mostly used to predict the flow of fluids or to match the properties of the reservoir. However, it has shown to have be limited when not enough information about the reservoir is available.Artificial neural network (ANN) is a technique used in many fields that has been able to compensate for some of the limitations associated with other approaches such as reservoir simulation. It relies on observed data to build highly non-linear and strong links among them that make it possible to obtain a more accurate prediction of the missing information.The main goal of this study is to develop an ANN tool for a single phase unconventional gas reservoir that can predict reservoir properties such as porosity, permeability and compressibility. The tool applicability has been extended for a large range of data. It provides predictions from two network structures, cascade forward backpropagation and radial basis function with an option to compare them. Each of the ANN model, therefore, differs by the type of networks used, the porosity system (single or dual), the well inclination (0 to 90), and the transient data available (pressure or production rate). The performance of each network was evaluated using the average percent error, the mean bias error (MBE), and the root mean square error (RMSE).
