Available in PDF, EPUB and Kindle. Book excerpt: Unconventional oil and gas production using hydraulic fracturing generates significant quantities of wastewater that may contain potentially harmful pollutants. The concerns associated with shale gas development necessitate an investigation of shale gas water and wastewater management using a systematic approach to make sure that shale gas development is environmentally sustainable. In this research, we adopt an integrated system analysis approach to examine the life cycle of water in the hydraulic fracturing process. Specifically, we developed a multi-objective programming model for shale gas water and wastewater management that incorporates the objectives of four types of decision-makers: oil and gas well developers and operators, centralized wastewater treatment facility planners and operators, environmental regulators, and social planners. This paper lays out a modeling framework that can, in the future, be used for a case study of optimal shale gas water and wastewater management. It also provides directions for future expansion of the model.

The processes for the extraction of shale gas from shale rocks are very complex. In this study, a multi objective optimization framework is presented for an overall water management system that includes the allocation of freshwater for hydraulic fracturing and optimal management of the resulting wastewater with different techniques. The generated wastewater from the shale fracking process contains highly toxic chemicals. The optimal control of a massive amount of contaminated water is quite a challenging task.

Available in PDF, EPUB and Kindle. Book excerpt: This analysis focused primarily on three main treatment methods which were re-use, recycle, and disposal wells. The re-use treatment option is when wastewater is mixed with source water in order to meet fracturing water requirements. With this option, the hope is that the wastewater for re-use will require little or no treatment at all. The second treatment option is the recycle option. This option provides high quality water for re-use or discharge to the environment using a recycling technology. The credibility of this option is heavily dependent on its ability to recycle almost all of the wastewater with little or none left for disposal or treatment. The third option is well disposal. This entails disposing all of the wastewater into a deep formation. The software used for building the model is called @Risk. The model's costs were estimates from recent research to capture the risks and uncertainties associated with wastewater disposal. The model revealed that re-use option remains the most cost effective treatment method to reduce overall water management cost in the Marcellus. The re-use option is most viable when a hydraulic fracturing schedule is continuous (no significant storage requirement) and infrastructure is available to transport wastewater from one fracturing operation to the other. The recycle option is the second most viable disposal option. This option is most effective when the hydraulic fracturing schedule is staggered in both time and distance because distilled water from recycling facilities can be easily discharged into the environment or stored. The most unfavorable option for wastewater management at the Marcellus is the well disposal option due to the high cost of trucking wastewater to disposal wells in neighboring states or counties. It also requires the highest usage of fresh water. A well disposal option can be favorable at the onset of a hydraulic fracturing schedule when there are low levels of infrastructure, hydraulic fracturing programs are not continuous or localized in proximity, and the volume of wastewater does not exceed the capacity for injection. In this case, disposal wells can be more favorable than recycle or re-use if they are in close proximity to drilling sites.

This book was released on 2015 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shale gas has become one of the most rapidly developing natural gas, providing approximately half of the natural gas for the U.S. Together with the development of shale gas exploration, large quantity of flowback and produced water is being produced. Management of flowback and produced water has become one of the most challenging issues for shale gas operators. Traditional disposal of flowback and produced water is challenged by the increased freshwater demand, water shortage, and more restraining regulations. Beneficial reuse of flowback and produced water is becoming a more attractive option, as it reduces freshwater demand for hydraulic fracturing, minimizes disposal costs, and helps to meet regulations. This study aimed to develop a decision-support tool for shale gas produced water management, treatment and beneficial use. Water quality and quantity data were retrieved from national produced water database and industrial database. Treatment technologies were critically reviewed about their capacities to treat shale gas flowback and produced water. A case study was conducted to evaluate shale gas flowback and produced water beneficial use potentials in Tioga County and Washington County in Marcellus Shale, Pennsylvania. The results showed that the costs of produced water treatment and beneficial use decreased significantly as the treated water flow rate increased. Produced water reuse is more cost-efficient than deep well injection when flowback and produced water from a cluster of wells collected together, and treated in a satellite facility. Small operators are recommended to cooperate to treat and reuse shale gas wastewater together to be more cost-effective. In addition to monetary benefits, reuse of flowback and produced water also augments water resources, reduces the industry reliance on local water supplies, decreases the risks of wastewater spill, remits traffic load and road wearing, helps to meet regulations and policies, and reduces public concerns.

This book was released on 2014-09-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas in deep shale formations, which can be developed by hydraulic fracturing and associated technologies (often collectively referred to as "fracking") is dramatically increasing production of natural gas in the United States, where significant gas deposits exist in formations that underlie many states. Major deposits of shale gas exist in many other countries as well. Proponents of shale gas development point to several kinds of benefits, for instance, to local economies and to national "energy independence". Shale gas development has also brought increasing expression of concerns about risks, including to human health, environmental quality, non-energy economic activities in shale regions, and community cohesion. Some of these potential risks are beginning to receive careful evaluation; others are not. Although the risks have not yet been fully characterized or all of them carefully analyzed, governments at all levels are making policy decisions, some of them hard to reverse, about shale gas development and/or how to manage the risks. Risks and Risk Governance in Shale Gas Development is the summary of two workshops convened in May and August 2013 by the National Research Council's Board on Environmental Change and Society to consider and assess claims about the levels and types of risk posed by shale gas development and about the adequacy of existing governance procedures. Participants from engineering, natural, and social scientific communities examined the range of risks and of social and decision-making issues in risk characterization and governance related to gas shale development. Central themes included risk governance in the context of (a) risks that emerge as shale gas development expands, and (b) incomplete or declining regulatory capacity in an era of budgetary stringency. This report summarizes the presentations on risk issues raised in the first workshop, the risk management and governance concepts presented at the second workshop, and the discussions at both workshops.

Download or read book Water Management Practices Used by Fayetteville Shale Gas Producers written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water issues continue to play an important role in producing natural gas from shale formations. This report examines water issues relating to shale gas production in the Fayetteville Shale. In particular, the report focuses on how gas producers obtain water supplies used for drilling and hydraulically fracturing wells, how that water is transported to the well sites and stored, and how the wastewater from the wells (flowback and produced water) is managed. Last year, Argonne National Laboratory made a similar evaluation of water issues in the Marcellus Shale (Veil 2010). Gas production in the Marcellus Shale involves at least three states, many oil and gas operators, and multiple wastewater management options. Consequently, Veil (2010) provided extensive information on water. This current study is less complicated for several reasons: (1) gas production in the Fayetteville Shale is somewhat more mature and stable than production in the Marcellus Shale; (2) the Fayetteville Shale underlies a single state (Arkansas); (3) there are only a few gas producers that operate the large majority of the wells in the Fayetteville Shale; (4) much of the water management information relating to the Marcellus Shale also applies to the Fayetteville Shale, therefore, it can be referenced from Veil (2010) rather than being recreated here; and (5) the author has previously published a report on the Fayetteville Shale (Veil 2007) and has helped to develop an informational website on the Fayetteville Shale (Argonne and University of Arkansas 2008), both of these sources, which are relevant to the subject of this report, are cited as references.

Available in PDF, EPUB and Kindle. Book excerpt: The United States has seen resurgence in petroleum production, mainly driven by technology improvements -- especially hydraulic fracturing and directional drilling -- developed for natural gas production from shale formations. Application of these technologies enabled natural gas to be economically produced from shale and other unconventional formations, and contributed to the United States becoming the world's largest natural gas producer in 2009. This book focuses on the growth in U.S. oil and natural gas production driven primarily by tight oil formations and shale gas formations. It reviews selected federal environmental regulatory and research initiatives related to unconventional oil and gas extraction, including the Bureau of Land Management (BLM) proposed hydraulic fracturing rule and Environmental Protection Agency (EPA) actions. The book also provides a technological assessment of existing and emerging water procurement and management practices in shale energy producing regions of the United States.

Download or read book Regulating Water Security in Unconventional Oil and Gas written by Regina M. Buono and published by Springer Nature. This book was released on 2019-10-31 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the need for deeper understanding of regulatory and policy regimes around the world in relation to the use of water for the production of ‘unconventional’ hydrocarbons, including shale gas, coal bed methane and tight oil, through hydraulic fracturing. Legal, policy, political and regulatory issues surrounding the use of water for hydraulic fracturing are present at every stage of operations. Operators and regulators must understand the legal, political and hydrological contexts of their surroundings, procure water for use in the fracturing and extraction processes, gain community cooperation or confront social resistance around water, collect flow back and produced water, and dispose of these wastewaters safely. By analysing and comparing different approaches to these issues from around the globe, this volume gleans insights into how policy, best practices and regulation may be developed to advance the interests of all stakeholders. While it is not always possible to easily transfer ‘good practice’ from one place to another, there is value in examining and understanding the components of different legal and regulatory regimes, as these may assist in the development of better regulatory law and policy for the rapidly growing unconventional energy sector. The book takes an interdisciplinary approach and includes chapters looking at water-energy nexus security in general, along with issue-focused and geographically-focused case studies written by scholars from around the world. Chapter topics, organized in conjunction with the stage of the shale gas production process upon which they touch, include the implications of hydraulic fracturing for agriculture, municipalities, and other stakeholders competing for water supplies; public opinion regarding use of water for hydraulic fracturing; potential conflicts between hydraulic fracturing and water as a human right; prevention of induced seismic activity, and the disposal or recycling of produced water. Several chapters also discuss implications of unconventional energy production for indigenous communities, particularly as regards sustainable water management. This volume will be of interest to scholars and students of energy and water, regulators and policymakers and operators interested in ensuring that they align with emergent best global practice.

Download or read book Water Management in Hydraulic Fracturing a Planning and Decision Optimization Platform written by Neha Mehta (S.M.) and published by . This book was released on 2014 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in hydraulic fracturing technology have enabled cost-effective production of unconventional resources, particularly shale gas in the U.S. The process of hydraulic fracturing is water intensive, requiring 4-7 million gallons of water per well, to which a range of chemicals must also be added in order to produce an effective fracturing fluid. Following a fracturing stimulation, anywhere from 10-40% of the injected volume of the water flows back to the surface as a polluted stream of wastewater. This polluted stream of water and the overall inefficient use of water in the hydraulic fracturing process has resulted in a number of negative environmental consequences, specifically surrounding ground and surface water quality and quantity. In considering how to minimize the environmental impacts of hydraulic fracturing, effectively managing water throughout the entire hydraulic fracturing water cycle (water acquisition and disposal) is obviously critical. This dissertation articulates a GIS based optimization model that has been developed to optimize water management planning for unconventional oil and gas production. The model enables a diverse set of stakeholders to develop customized water management strategies based on the geological characteristics and water infrastructure of any given play. The model comprises of a front end GIS interface and a back end optimization engine, designed to minimize the overall system cost of water handling as well as minimizing the overall water footprint of the system. Altogether, it is a powerful decision making tool, which allows the operators to optimize and analyze the temporal and spatial variations in flowback, and produced water management and provide an operationally convenient method to access and share the model analysis. From a regulatory perspective, the modeling framework provides a comprehensive template for a water management plan and could be used as a basis to develop tailored, customized regional solutions that can incorporate the inherent heterogeneity widespread across today's oil and gas plays.

Available in PDF, EPUB and Kindle. Book excerpt: In the past, the oil and gas industry considered gas locked in tight, impermeable shale uneconomical to produce. However, advances in directional well drilling and reservoir stimulation have dramatically increased gas production from unconventional shales. There may be as much as 200 trillion cubic feet of natural gas technically recoverable from these shales. There is an expectation that the demand for natural gas will increase. Developing these shales comes with some controversy.
