  • Inert gas supply equipment for oil and gas well operations
    Patent number: 9103190
    Abstract: An apparatus for the supply of inert gas at a well site, the apparatus comprising one or more pressure vessels containing liquefied inert gas, a heat exchanger, one or more units of fracturing equipment connected to a manifold, a submersible pump in each of the one or more pressure vessels, each submersible pump being connected to supply liquefied inert gas to a supply line that passes through the heat exchanger and the supply line being connected to supply inert gas vaporized by the heat exchanger to the manifold.
    Type: Grant

  • Integrated "One Pump" Control of Pumping Equipment
    Publication number: 20090053072
    Abstract: Methods and systems for improving the efficiency of a pumping process by controlling the operation of the pumps involved based on certain parameters characterizing the pump. A pump unit is coupled to a pump controller which is in turn, coupled to a pump modulator. A master controller drives the pump modulator based on a desired output parameter for the system. The pump modulator then drives each pump unit through its corresponding pump controller in a manner for the system to achieve optimal performance.

  • Method of Blending Hazardous Chemicals to a Well Bore
    Publication number: 20080190618
    Abstract: A method for blending a well treatment fluid at a well site, including (1) providing centrifugal pumps for pumping components of the well treatment fluid into a pipe, (2) providing valves for controlling the flow of the components of the well treatment fluid into the pipe, and (3) controlling the pumps and the valves so as to control the ratio of the components of the well treatment fluid being delivered to the pipe.
