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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
