Groundwater Protection & Usage
Hydraulic fracturing requires large quantities of water.
Oil and natural gas producers have developed multiple ways to obtain the water necessary for wells that are hydraulically fraced.
Building ponds and reservoirs to capture rain, recycling water and contracting with public works and farmers are some of the innovative ways the industry is obtaining, monitoring and regulating water usage in areas.
Casing is a process that is regulated by the state for each hydraulically fractured well site.
Well casing acts as a protective barrier between hydraulic fracturing fluid, oil and natural gas that flows through the well and the fresh water aquifers. The process involves sealing the drilling well bore in multiple layers of cylindrical steel pipes encased in multiple layers of cement.
The casing layers extend underground with the Surface casing reaching anywhere from 50-1,500 feet below freshwater aquifers. Production casing can extend from 5,000-10,000 feet underground.
