摘要

While other neighboring geothermal energy plants are located around sea level and enjoy artesian production with moderate flow and surface pressures to supply their power plants, the Limgaz Organic Rankine Cycle (ORC) power plant in Turkey is situated at an elevated location around 1312ft (400m) above the sea level. Therefore, the static fluid level in the wells was at approximately 300 meters below the wellhead. The expected brine temperature was around 300°F (150°C) from the production wells. In 2014, two wells were simultaneously tested using electrical submersible pumps (ESP). At this time, the operator was also able to determine interaction between their wells allowing the calculation of operational and financial feasibility of their future power plant. The study resulted in investment and successful completion of a 13.8 MW ORC geothermal power plant in 2018. This particular application is an important reference for the role that downhole pumping units play in the low enthalpy geothermal systems, as the production for the ORC is 100% dependent on 5 ESPs. This case study highlights the combined technology packages employed to accommodate different well characteristics and flow conditions of each well and the brine production overall.
