Exploitation Of Unconventional Oil And Gas Resources

As the shale revolution continues in North America, unconventional resource markets are emerging on every continent. In the next eight to ten years, more than 100,000 wells and one- to two-million hydraulic fracturing stages could be executed, resulting in close to one trillion dollars in industry spending. This growth has prompted professionals ex

The stimulation of unconventional hydrocarbon reservoirs is proven to improve their productivity to an extent that has rendered them economically viable. Generally, the stimulation design is a complex process dependent on intertwining factors such as the history of the formation, rock and reservoir fluid type, lithology and structural layout of the formation, cost, time, etc. A holistic grasp of these can be daunting, especially for people without sufficient experience and/or expertise in the exploitation of unconventional hydrocarbon reserves. This book presents the key facets integral to producing unconventional resources, and how the different components, if pieced together, can be used to create an integrated stimulation design. Areas covered are as follows: • stimulation methods, • fracturing fluids, • mixing and behavior of reservoir fluids, • assessment of reservoir performance, • integration of surface drilling data, • estimation of geomechanical properties and hydrocarbon saturation, and • health and safety. Exploitation of Unconventional Oil and Gas Resources: Hydraulic Fracturing and Other Recovery and Assessment Techniques is an excellent introduction to the subject area of unconventional oil and gas reservoirs, but it also complements existing information in the same discipline. It is an essential text for higher education students and professionals in academia, research, and the industry.

Unconventional Gas and Tight Oil Exploitation takes an in-depth look at unconventional low-permeability resource accumulations, the required technologies for specialized development, and the assessments currently being applied. With an author team of 14 subject-matter experts with specialization in different tight oil and unconventional-gas areas, this new book is an authoritative resource for those looking to increase recoverable resources. A must read for those wanting to make a significant positive impact on global energy markets while respecting the environment. Changes to global energy markets, shifts in international oil-supply projections, advancements in horizontal drilling and multistage hydraulic-fracturing technologies-these realities coalesce to potentially extend natural gas and oil supplies by several decades by current levels of consumption. In Unconventional Gas and Tight Oil Exploitation, the authors lend their expertise to offer an in-depth look at unconventional low-permeability resource accumulations, the required technologies for specialized development, and the assessments currently being applied. While percent recoveries from unconventional gas and tight oil accumulations have been very low compared with conventional reservoirs, these unconventional resources have been enough to dramatically change the slope of production decline in the United States from negative to positive in a very short period of time. This change of slope is "magic" and reflects the creativity of the oil and gas industry. The authors of this book seek to ascertain and explore the challenges and opportunities associated with the current commercial development techniques in an effort to fully understand the reservoirs, the mode of petroleum storage and transport within the reservoirs, the design of drilling and completion programs, and the physics behind formation analyses. Through this understanding, unconventional gas and tight oil exploitation techniques can be developed further, resulting in low production costs, improved economics, increase in technically recoverable resources while respecting the environment, and significant positive impact of gas and tight oil developments globally.

Oil and gas well completion and stimulation technologies to develop unconventional hydrocarbon resources in the United States have evolved over the past several decades, particularly in relation to the development of shale oil and shale gas. Shale oil and shale gas resources and the technology associated with their production are often termed "unconventional" because the oil and gas trapped inside the shale or other low-permeability rock formation cannot be extracted using conventional technologies. Since about 2005, the application of these technologies to fields in the U.S. have helped produce natural gas and oil in volumes that allowed the country to reduce its crude oil imports by more than 50% and to become a net natural gas exporter. The regional and national economic and energy advances gained through production and use of these resources have been accompanied, however, by rapid expansion of the infrastructure associated with the development of these fields and public concern over the impacts to surface- and groundwater, air, land, and communities where the resources are extracted. The intent of the first day of the workshop of the National Academies of Sciences, Engineering, and Medicine's Roundtable on Unconventional Hydrocarbon Development was to discuss onshore unconventional hydrocarbon development in the context of potential environmental impacts and the ways in which the risks of these kinds of impacts can be managed. Specifically, the workshop sought to examine the lifecycle development of these fields, including decommissioning and reclamation of wells and related surface and pipeline infrastructure, and the approaches from industry practice, scientific research, and regulation that could help to ensure management of the operations in ways that minimize impacts to the environment throughout their active lifetimes and after operations have ceased. This publication summarizes the presentations and discussions from the workshop.
