There is potential to profitably utilize mature or abandoned oil field infrastructure to produce geothermal electricity, called coproduction. Although many oil reservoirs have only a moderate temperature range, utilizing mature or abandoned oil infrastructure sidesteps the capital intensive initial investment to drill new wells and eliminates the need and associated risk of induced fracturing, a practice currently under much scrutiny in application for EGS. Power generation from coproduced fluids using a binary-cycle power plant is underway at the Rocky Mountain Oilfield Testing Center in Wyoming and being considered in locations in Texas, Louisiana, Florida, and Arkansas. California is another good candidate for coproduction
