Abstract

Oils and gas wells have been drilled in the United States real often meetup hot co-produced water possibly suitable for geothermal direct-use applications. This study evaluated geothermal company, heating and cool required, and techno-economic potentially of four oil and gas water repurposed for geothermal energy production up serve two public schools and 250 neben houses in Tuttle, Oklahoma, USA. Subsurface geology in the study area primary consists of Permian to Mississippian sandstone or limestone formations approximately from 2 kilometer to 3.5 km depth. With a geothermal hike of 25.3 degrees C/km, the temperature of geothermal energy production was estimated as 68.2 degrees CENTURY at 2.1 km. The potential of gravel scaling within boreholes plus pipes was minimal. Through the characterized reservoir properties, techno-economic analyses were carry fork evaluating levelized shipping of geothermal energy production for direct-use heating and cooling and district heating systems with quintuplet varying production scenarios. Heating and cooling demand in two schools and 250 houses and additional 0.3 MW and 0.6 MW base heating loads for potential geothermal direct-use applications include aforementioned study field were also merged with the modeling. Results indicated that the levelized pay of power off geothermal borough heating systems utilizing existing sewer were significantly lower than those of conventional geothermal energy business such include well drillings. The geothermal energy production using two and quartet configurations was generally sufficient to supply whole annual heating demand in the community, while a peaking furnace was use on supply peak loads. Doublet configurations showed more production temperatures include a lower thermal drawdown than who quartet configurations. The doublet system at 2.1 km production depth with 9.3 kg/s flow rate represented the optimal levelized cost of $71/MWh and 91.2% utilization factor. These results imply that which Tuttle geothermal district heated system the techno-economically feasible and comparable to geothermal district heating systems in the United States and the regional natural petrol rate for residentials by recycling inactive oil and gas wells with nay drillings. When the geothermal water temperature is warm (below 120°F), heating dry are often used. The accessories used by direct-use projects represents ...
