43、. . . . . . . 37Executive SummaryThe oil and gas industry has significant connections to the water environment. Water is beneficially used, consumed, generated, reused, recycled, and disposed of over the life cycle of an oil and gas resource. The degree and impact of these connections vary with the

44、nature and location of the resource and the methods of extracting and converting that resource into valuable end products.This report uses the oil and gas (petroleum) life cycle represented in Figure ES.1 as an organizing framework for explanation and discussion. As depicted in Figure ES.1, the scop

45、e of this study is focused on the midstream, downstream, and delivery components of the oil and gas life cycle. Upstream components of the life cycle will be addressed in a future report.This study describes water use, management, and stewardship practices, the existing regulatory framework, quantit

46、ative water footprint information, and comparison of water use to other industry and societal uses.Water UseWater is used throughout the midstream, downstream, and delivery phases of the oil and gas life cycle. The most significant of these uses, however, is for oil refining. The raw material of the

47、 petroleum refining industry is petroleum material such as crude oil. Petroleum refineries process this raw material into a wide variety of petroleum products, including gasoline, fuel oil, jet fuel, heating oils and gases, and petrochemicals. Petroleum refining includes a wide range of physical sep

48、aration and chemical reaction processes.Water use in gas processing, oil and gas transmission (midstream) and oil and gas delivery phases is negligible compared to the amount of water required for oil refining. Therefore, this section focuses on water use in oil refining. In petroleum refineries, wa

49、ter is vital for many applications including crude desalting, scrubbing, cooling, steam production, utility water, fire protection, and more. Refineries depend on uninterrupted and sustainable water supplies to maintain production and safety. Refineries also generate wastewaters which are typically reused or discharged to the environment (mainly fresh and marine water bodies) after the appropriate level of treatment to meet regulated discharge limits. These limits vary from one location to another. In ecologically sensitive areas, a higher degree of effluent treatment may be required to a
