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. A plurality of sensors and gauges strategically mounted within the system ensure safe operation of the system in the field. The system is mounted on a portable skid that can be delivered to the field and removed upon completion of the cleaning, treating and/or reservoir stimulation operation.
