Impact of well placement and flow rate on production efficiency and stress field in the fractured geothermal reservoirs

Abstract

	•The long-distance well placement has a longer heat transfer path and absorbs more heat; the higher the mass flow rate, the larger the expansion range.
	•Long-distance well locations can improve production efficiency; short-distance well locations can reduce the heat transfer area, which will reduce the impact on the reservoir stress field.
	•The increase in mass flow rate will reduce the outlet temperature of the production well but increase the total amount of heat energy absorbed by the reservoir.
