  • Patent number: 7896978
    Abstract: A reservoir cleaning, treating and/or stimulation system allows the operator to control the speed and pressure of delivery of the treating fluid into the reservoir and remove or dissolve sediment particles settled in the reservoir or the reservoir formation. The system uses a thermal heater capable of heating the treating fluid from ambient temperature to about 400 degrees Fahrenheit. A charge pump mounted on an intake side of the heater forces the treating fluid through the heater, while the treating fluid passes through the tubing of the heater. The heated treating fluid is channeled to a discharge pump on an outlet side of the heater, where the treating fluid is pressurized to a value sufficient to overcome the pressure existing within the reservoir and cause displacement or dissolution of the sediment in the reservoir. A flow meter mounted between the heater and the charge pump regulates the volume of the treating fluid being admitted into the heater.

  • Publication number: 20070289617
    Abstract: A system for cleaning, treating, and/or stimulating a reservoir in a high pressure, low volume application or a low pressure, high volume application, comprising: a thermal fluid heater capable of generating energy in the form of superheated air that is circulated through the heater to heat a working fluid that is forced through tubes within the heater: an air compressor for atomizing the fuel and creating a fuel/air mixture; a blower for blowing ambient air into the atomized fuel/air mixture in the heater to raise the temperature of the working fluid; a charge pump on the intake side of the heater for forcing the working fluid through the heater at a pressure and volume sufficient to supply the working fluid to an outlet of the heater; a discharge pump on the outlet side of the heater to increase the pressure of the working fluid as it exits the system to a sufficient pressure and volume to clean, treat, and/or stimulate the reservoir for a particular selected application; and a prime mover or prime movers f
