Evolution of physico-chemical characteristics of the fluids discharged during a monitored six-month production test at Momotombo points to rapid transformation of the reservoir from water-, to steam-dominated. The transformation followed an invasion of the peripheries of the hot reservoir by cold ground water from the pyroclastic and lacustrine formations underneath Lake Managua. Rapid cooling of the periphery of the geothermal reservoir led to intraformational precipitation of silica, sealing off the reservoir to any fresh recharge. The process was reflected in radical changes in pressure, temperature and production rates, accompanied by significant evolution of chemical parameters of the discharged fluids, such as B/C1, Na/K and Na/C1 ratios, and concentrations of silica, chloride, sulfate and boron.
