Reducing fracing chemcials
Chemical additives for hydraulic fracturing are a growing concern with significant public focus. Chemicals are added to inhibit corrosion and deposition and control bacterial growth. One way to reduce chemical demand downhole is by conditioning the water before use. GE mobile surface water filtration will do just that, as well as reduce operating costs for chemicals. Designed to work with fracturing volumes and flowrates, the result is much lower solids and bacterial counts at the wellhead. Less bacteria means reduced need for biocides, and fewer solids means lower tendency to deposit.
Operating disposal wells can often be an expensive proposition. Solids collect in tanks and become breeding grounds for bacteria that create acids that attack equipment as well as H2S, risking health and environmental safety issues. Solids carryover to injection can destroy pumps and may ultimately lead to well plugging. The only solution seems to be more and more chemicals to prevent corrosion and control biological growth. GE can reduce chemical use through a filtration process that reduces solids and bacteria. The result is longer intervals between tank cleanings, reduced chemical costs and improved life expectancy for the disposal well and its infrastructure.
Central Water RecyclingIn addition to mobile systems, GE has a long history of fixed thermal and membrane systems for produced water recycling and reuse. For high TDS waters, GE’s thermal evaporator and crystallizer systems can reduce the waste stream by as much as 95% while yielding distilled water and marketable salt products.
For low TDS systems, GE employs a wide portfolio of technologies for water conditioning. Solutions can include membranes, membrane bioreactors and other equipment depending on water quality.
