Management of produced water from oil and gas wells

15 Sep 2011 THE ROLE OF WATER IN OIL AND GAS PRODUCTION . B. Technologies and Options for Managing Produced Water . Instead, since a majority of wells produce less energy per day, production is compensated by drilling dense well populations to increase production in a field. The  Consequently, for oil and gas production wells located in water-scarce regions, limited freshwater resources in conjunction with the high treatment cost for 

recycled and reused within the oil and gas field for drilling and hydraulic fracturing activities. While opportunities exist to recycle/reuse produced water outside of the oilfield, this management approach is rare. Some produced water is currently used for irrigation of crops. Produced water is the largest waste stream from oil and natural gas production. The large volume (15 to 20 billion barrels generated annually in the U.S.) and high salinity (5,000 to 270,000 mg/L TDS) of produced water could pose severe environmental impacts upon inadequate disposal. “Occidental separates produced water, which is typically saline, from the produced oil and gas, and recycles it in a closed loop by reinjection into mature oil and gas reservoirs as part of its improved oil recovery (IOR) or enhanced oil recovery (EOR) operations,” the company said. Optimal oilfield water management requires knowledge of reservoir characteristics, production volumes, hydrogeology, engineering design, and environmental considerations. Schlumberger has a deep understanding of the subsurface, combined with the unrivaled engineering experience necessary to address the technical aspects of oil and gas water challenges.

Produced water is a term used in the oil industry to describe water that is produced as a byproduct during the extraction of oil and natural gas.Oil and gas reservoirs often have water as well as hydrocarbons, sometimes in a zone that lies under the hydrocarbons, and sometimes in the same zone with the oil and gas.

These fractures allow the oil and gas to move from the formation into the well. The challenge of managing produced water from these kinds of operations  Which wastes generated from offshore oil and gas exploration and production Routine discharges may include water-based drilling muds and cuttings, of a well, drilling fluids or "muds" are used to lubricate and cool the drill bit, control 

Treatment of produced water may be If the oil and gas operator wishes to Produced water from oil wells is to be treated stepwise within the treatment facility .

These fractures allow the oil and gas to move from the formation into the well. The challenge of managing produced water from these kinds of operations  Which wastes generated from offshore oil and gas exploration and production Routine discharges may include water-based drilling muds and cuttings, of a well, drilling fluids or "muds" are used to lubricate and cool the drill bit, control  Produced water is by far the largest volume byproduct stream associated with oil and gas exploration and production. Approximately 21 billion bbl (barrels; 1 bbl = 42 U.S. gallons) of produced water are generated each year in the United States from about 900,000 wells.

oil and gas can choose from a number of practices to manage and treat produced water, but underground injection is the predominant practice because it requires little or no treatment and is often the least costly option.

formation water, injection water, and any chemicals added downhole or during the oil/water separation process.” 2 EPA defines unconventional oil and gas at 40 CFR 435.33(a)(2)(i) as “crude oil and natural gas produced by a well Extraction of oil and gas from underground reservoirs often is accompanied by water or brine, which is referred to as produced water. As reservoirs mature, especially if secondary or tertiary recovery methods are used, the quantity of water climbs and often exceeds the volume of the hydrocarbons before the reservoir is exhausted. Voluntary Management Practices for Oil and Gas Exploration and Production Wastes. In concert with the application of state regulatory requirements, there are a variety of voluntary management practice guidance (often referred to in industry as "Best Management Practices," or "BMPs") for operators to evaluate and use in the development of site-specific exploration and production waste unconventional wells – all water returning to the surface from oil and gas wells is counted as produced water for the sake of volume estimates. Produced Water Volume A 2009 report1 made a national produced water volume estimate for the 2007 calendar year of 21 billion barrels (bbl; 1 bbl = 42 U.S. gallons) per year for the entire United States. Produced water is a term used in the oil industry to describe water that is produced as a byproduct during the extraction of oil and natural gas.Oil and gas reservoirs often have water as well as hydrocarbons, sometimes in a zone that lies under the hydrocarbons, and sometimes in the same zone with the oil and gas. There are three major fluids that come out of a well, and these are gas, crude oil and water. During the production stages the well not only flow hydrocarbons it also flow water. Produced water is water trapped in underground formations that is brought to the surface along with oil or gas. Produced water from oil and gas operations is currently handled as a waste product. The quality of produced water varies significantly based on the geochemistry of the producing formation, the type of hydrocarbon produced, and the

The growth of shale gas and oil production has resulted in the emergence of a new challenge in water management - namely, the disposal/treatment of Produced 

Consequently, for oil and gas production wells located in water-scarce regions, limited freshwater resources in conjunction with the high treatment cost for  As part of the process of producing oil and natural gas, operators also must manage large quantities of water that are found in the same underground formations. Some of the options available to the oil and gas operator for managing produced water might include the following: 1. Avoid production of water onto the surface  In our state and in other mature oil and gas production areas, the majority of wells produce brine water along with gas and oil.
