Rising populations, regional droughts, and declining groundwater levels are among the many factors driving freshwater stress in the United States. According to a new report released by the Groundwater Protection Council (CWPC), produced water may become a resource that reduces the use of fresh water in specific locations. "We are concerned about the overuse of fresh groundwater resources, and we wanted to explore how produced water might help fill that gap," GWPC Executive Director Mike Paque said in a statement. "By identifying opportunities and challenges of using produced water and offering options for addressing them, we hope to facilitate the development of produced water as a supplement to freshwater resources." The report addressed the drivers and potential benefits for increasing produced-water reuse in unconventional oil and gas operations and outside the industry, as well as the economic, scientific, regulatory, and policy considerations, particularly with respect to risk management.

Abstract This study aims to measure the water footprint for conventional oil production over the entire life cycle. The overall methodology for the development of net water footprint (cubic meters of water/barrel of oil produced) included the modelling of different unit operations and an assessment of both primary and secondary data. A case study for three fields of Mansarovar Energy, Colombia, was performed. A water footprint calculation allowed the organization to carry out a sustainability analysis of resource consumption, improve corporate image strategies, detect avoidable consumption costs and optimize processes and operations. It also provided specific actions with which to tackle sector sensitivity and answer stakeholder concerns with regards to responsible water use. These results are relevant in the decision making process for oil production. The following steps in the management process of water footprint were developed: a description of facilities and processes, organizational and operational boundaries in the definition of a functional unit; a water inventory, in order to quantify resource inputs and outputs; calculations of blue, green and gray water footprint; an assessment as to the degree of water footprint sustainability and water stress; actions to reduce the water footprint. Results indicate that the blue water footprint was the most significant compared to the green and gray. The value, the first ever calculated for a Colombian hydrocarbon company, was between 0.2 and 0.4 m/barrel, considering both indirect and direct consumption.

Abstract Water is one of earth's most critical resource, since it is essential for life. The consequences of climate change and the actual projections of increasing water demand will affect the water availability and also cause the deterioration of the quality of water bodies, leading to new scenarios of water stress at a global level. In this framework, energy companies must consider sustainable options for the use of this resource, especially in water scarce regions. In this framework, Eni is committed to identify and reduce the business risks connected to the water resources and to pursue the following principles: • Water Conservation: Energy operations may need to access significant quantities of high-quality water, in terms of water with low salinity content. The key elements to the conservation of water resources include the reduction of withdrawals and the efficiency in water use, together with the application of best operational practices at local and watershed levels, the stakeholder engagement and the control of associated risks. • Water Reuse and Valorization: Design solutions shall recycle water within the production cycle, adopting treatment that make discharges compatible with the reuse of industrial water, including produced water, in the same production cycle or by third parties (e.g. local communities, other plants), instead of discharging it as wastewater. To identify possible improvements in water management for its sites and to foster initiatives for increasing water sustainable practices, Eni has adopted a methodological approach based on the following steps: - A country-based framework study, to properly understand the context and the current situation of water resources and water-related risks in countries where Eni operates; - A site level Water Balance, gathering quantitative information related to water management, and in particular on water quality, sources, uses, and final destinations of water streams. The objective is to gain a better overview and control of how water is managed/used within the site. - Site initiatives: feasibility studies are performed with the aim of identifying initiatives and implement projects for the reuse and valorization of produced water, as well as for the reduction/optimization of high-quality water withdrawals, both for domestic and industrial uses, within and outside the operative site. Through this approach, water risks associated with operations are being analyzed in detail, allowing to address a wide range of opportunities for the improvement of water management, also through the development of new synergies with local communities.

ABSTRACT The objective of this paper is to demonstrate the process followed to reduce raw water consumption in an oilsand extraction and upgrading facility, located in Northern Alberta, Canada. To successfully reduce raw water consumption it is critical to understand where the water is used, how the water is used, and to develop alternative sources/supplies of water. A site-wide water management program was initiated in 2003 to address increasing water inventories within the tailings ponds. Results achieved to date, on-going projects as well as path forwards are presented in this case study. INTRODUCTION The facility is a major oilsands mining, extraction, and bitumen upgrading operation that is currently in an expansion process. Present oil production is approximately 90 Mbbls/year. Post expansion will increase the annual production to approximately 135 Mbbls/year. Two major sources of water are used in the upgrading, extraction, and utility components of the plant: recycle water and raw water. Recycle water or process water is the primary source of water for the oilsand extraction process. The recycle water pond provides cooling water for the upgrader and supplies hot process water for the oilsand extraction process in a heat-integrated manner. Once the bitumen has been extracted, the sand and water slurry are discharged to tailings ponds where free water is collected. The water is then pumped back to a centralized pond referred to as the recycle water pond. Raw water from the Athabasca River is the makeup water source for the following plant services: cooling towers, utility water, firewater, gland water, water treatment plant, and potable water treatment plant. All of the imported raw water reports to and is contained in the tailings ponds with the exception of evaporative water losses (i.e. cooling towers), water consumed in chemical reactions (i.e. hydrogen production), and sanitary sewer effluent which is treated and subsequently discharged to the environment. The volume of water reporting to tailings has historically been in balance with the tailings water demand. This demand arises because water is consumed or lost in the void spaces of the tailings materials consisting of sand, composite tailings(1), and mature fine tailings(2); and due to evaporative water losses to the atmosphere during slurry discharge to the various ponds.

Abstract Water is essential in oil and gas operations. Yet water, particularly fresh water, is a scarce resource in many parts of world now and availability in some regions is predicted to become more constrained in the future. This paper will address industry understanding of water risks and impacts and share examples of water management strategies that are integral to sustainable and efficient operations in the sector. Utilizing several publically available tools for improving understanding and evaluating risk, ConocoPhillips has continued to advance both our internal understanding of our risks and mitigation plans and contributed to raising the industry and stakeholder awareness of water management risks in the sector. Through our work with IPIECA, GEMI (Global Environmental Management Initiative) and other organizations, this paper showcases the evolution of the industry’s understanding, tools and guidance developed to better manage water risks, impacts and adaptation. As co-leader in the development of these tools, and from experience in their internal implementation, ConocoPhillips will share the evolution of the topic and the impact the following tools had in managing risks: The IPIECA Global Water Tool for Oil and Gas, customized in collaboration with the World Business Council for Sustainable Development (WBCSD), gives an overview and visual output of water use and risks for a global portfolio across the oil and gas value chain. The GEMI Local Water Tool for Oil and Gas provides a local-level understanding of water risk and development of asset-specific management plans. Development of a focused internal water strategy and areas of emphasis (supported by the IPIECA and GEMI tools) is expanding our transparency and internal understanding of water risks. The paper will share practical implementation results from utilizing these tools, support implementation of good management practices and environmental and operational performance.
