METHOD AND APPARATUS FOR CONTROLLING THE SPEED OF A PUMP IN A WELL

Номер: CA0002510101C

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.

METHOD OF CALCULATING PUMP FLOW RATES AND AN AUTOMATED PUMP CONTROL SYSTEM

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 .DELTA.V divided by a change in time .DELTA.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.

METHOD FOR MONITORING FLUID LEVELS IN A TANK

Номер: US20080125983A1

Принадлежит: NORALTA CONTROLS LTD.

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.
