Benefits of technology
This patent describes a surface heating system for production pipes that includes a heating tube and a baffle. The system is designed to transfer heat to the production tubing by pumping a heating element downhole through double-walled tubing and warming it with the heating element while it is in the tubing. The heating element can be reheated and then returned back into the tubing for recirculation. This system provides an effective way to heat production tubing to the required temperature to improve the efficiency of oil and gas production.
Problems solved by technology
One of the many problems in oil and gas production is maintaining adequate production flow.
Blockages, decreased flow, and total obstruction can occur in any well including wells that once had high flow.
Wells may become obstructed by paraffin and asphaltene deposits that attach to the inside of the tubing.
Asphaltenes and paraffins have the potential to interfere with production and in some instances can cause a complete shutdown.
During production, asphaltenes may destabilize and precipitate because of temperature changes, pressure, and / or the chemical composition of the crude oil.
Paraffins are similar to asphaltenes in that they too, can potentially interfere with or completely stop production.

Embodiment Construction
[0008]These and other needs in the art are addressed in one embodiment by a surface heating system disposed around production pipe. The system includes a heating tube. The heating tube includes an exterior tubing section. The heating tube further includes an interior tubing section. The heating tube still further includes a baffle. These and other needs in the art are addressed in another embodiment by a surface heating system disposed around production pipe. The system includes a heating tube. The heating tube is segmented into jackets. The heating tube includes an exterior tubing section. The heating tube further includes an interior tubing section. The heating tube still further includes a baffle. These and other needs in the art are addressed in another embodiment by a method of transferring heat to production tubing. The transferring of heat to production tubing includes pumping a heating element downhole through double walled tubing. The transferring of heat to production tubi...

A system and method allowing for the transfer of heat from a heating element in a tube heating system to production tubing in downhole pipes. The heating tube is comprised of double walled and double threaded pipe. The transferred heat warms the material being extracted from a subterranean formation and collected at the surface. Warming the material prevents the build-up of paraffins, asphaltenes, or other materials that may potentially clog production pipe in downhole applications.
Description
BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to systems and methods for producing, delivering, or transferring heat to the tubing or piping of producing or non-producing oil, gas, or water wells with the purpose of improving production therefrom.[0003]Background of the Invention[0004]One of the many problems in oil and gas production is maintaining adequate production flow. Blockages, decreased flow, and total obstruction can occur in any well including wells that once had high flow. Wells may become obstructed by paraffin and asphaltene deposits that attach to the inside of the tubing. Additionally, the oil itself can sometimes have such a high viscosity that flow decreases even under naturally ambient temperatures.[0005]Asphaltenes and paraffins are commonly occurring components of crude oil. Asphaltenes and paraffins have the potential to interfere with production and in some instances can cause a complete shutdown. Asphaltenes are la...
