Abstract: The heater block of the present disclosure can transfer heat from a heat transfer fluid to a received fuel fluid, air passing in proximity to the heater block or combinations thereof. These heat transfers reduce, substantially prevent or prevent the freezing of water within the received fuel fluid and/or the air as it enters an intake member of a gas burning unit.
Abstract: A method and apparatus for controlling a speed of a pump operating in a well. A first step involves monitoring a production flow rate of fluids produced from the well. A second step involves controlling the speed of the pump with reference to the production flow rate by increasing the speed of the pump when the production flow rate is rising and decreasing the speed of the pump when the production flow rate is declining.

Abstract: A method of determining a flow rate of a pump involves determining a volume capacity for a flow line carrying produced fluids from the pump, determining a starting pressure for the flow line and setting an arbitrary target pressure for the purpose of testing. The test is initiated by preventing flow in the flow line while continuing to operate the pump and monitoring pressure in the flow line to determine a time interval required to reach the target pressure. The method then involves performing calculations to determine flow rate using the volume capacity, the starting pressure, the change in pressure over the time interval required to reach the target pressure. The flow rate is equivalent to ?V divided by a change in time ?T. The method is preferably used as part of a manual or automated pump control strategy to keep the pump operating within flow rate ranges that provide optimum pump efficiency.
Abstract: A method for monitoring fluid levels in a tank. A first step involves modelling the tank to identify fluid zones of fluids having differing densities, the heat retention characteristics of each the fluid zones and the relative relationships between each of the fluid zones. A second step involves obtaining a heat profile of the tank. A third step involves analyzing the heat profile based upon the modelling to generate relative fluid level data for the tank.
Abstract: An apparatus for controlling a downhole pump. The pump has a stator, a rotor and a pump drive. The temperature monitoring apparatus includes at least one temperature sensor positioned downhole in thermal communication with the downhole pump for measuring the downhole temperature of the downhole pump, and a pump controller connected to the temperature sensor by a wireless communication link for receiving measurements from the temperature sensor. The pump controller has controls for controlling the speed of the pump.
