Water treatment technology for shale

U.S. shale development jobs are finding water treatment solutions. Water is the current U.S.  shale gas  development companies are very concerned about infrastructure and sanitation requirements of the practical issues related to them must solve the water problem.
Shale drilling for water issues, oil and gas industry is actively taking action because the current practice of water treatment problems will become unsustainable exploitation of shale gas. It can be said, the oil and gas industry is at a crucial crossroads, continue the successful development of shale oil and shale gas development companies depend on accelerating the adoption of new and emerging through the water treatment technology, thereby correcting their treatment program. Systemic change will require daily operation procedures to reduce logistical and environmental pressures, while providing sustainable water choices to ensure long-term development of shale gas resources.

Issue of access to water

Make a viable shale gas development project costs and logistics, especially in remote areas, it is very important. Development of a 650,000 square kilometers (25 square miles) of shale gas projects must receive billions of gallons of water. Optional water, including surface water, groundwater and municipal water (including fresh water and wastewater) and return drainage and the use of produced water. Horizontal wells in the drilling phase requires 2MMgal of water, and in the completion phase requires more than 10MMgal of water. The water must be transported to the wellhead, which are most likely to involve a range of services and logistical support for the work of manpower.

There are few people bring  Hydraulic fracturing  operations and safety of drinking water supplies questioned. Shale gas development can provide a wealth of information about the operator for fracturing evidence favorable, usually in the area has been set, only less than 1% water. However, in certain geographic area, the fracture may require relatively more water, the operator can see different makes water fracturing process. For example, in the U.S. Permian Basin, persistent drought conditions cause the water is restricted.
