These sensors are configured to diagnose downhole conditions and help free the stuck equipment downhole.

Abstract: This disclosure presents methods and systems of controlling a counter flow double pipe heat exchanger (DPHE) that includes a hot fluid pipe and a cold fluid pipe. In a method, a temperature error between a reference temperature and a temperature at an outlet of the hot fluid pipe of the counter flow DPHE is determined. A cold fluid mass flow rate is determined from an output of a proportional-integral-derivative (PID) controller based on the temperature error being input to the PID controller. The cold fluid mass flow rate is used for a cold fluid in the cold fluid pipe of the counter flow DPHE. The temperature error is controlled within a predefined range by utilizing parameters of the PID controller that are set by using a harmony search algorithm (HSA) to obtain a minimization of a cost function.

Multiple programmable solenoid valves are provided to individually control injection of the aeration coolant, the jacket coolant, and the coil coolant. A controller is provided to communicate with a temperature sensor and each programmable solenoid valve.
