Practical Alternative Microwave Technology to Enhance Recovery Heavy Oil in Reserviors

Abstract

Extracting of Heavy Oil (Hydrocarbon) from Tar Sand and Oil Shale in deep reservoirs 7,000-12,000 feet below the ground surface by using Circular Waveguides Technology and Microwave Energy High Power System. Using Circular Waveguides as microwave energy radiator connects to the Microwave High Power System is the most practical method and provides a relatively cost-effective means of extract heavy oil from target Tar Sand or Oil Shale in deep reservoirs. This invention method can be applied for future new well bores that are in the plan to be drilled. It also can be used for existing un-use well bores that are being closed; waiting for cleaner new enhance oil recovery technology becoming available in order to reclaim of heavy oil without damaging the environment.

AI Technical Summary

Benefits of technology

The invention uses a special technology called circular waveguide to heat tar sand and oil shale in deep reservoirs without needing additional water or chemical injections. This approach reduces viscosity and breaks down the hydrocarbons faster, increasing oil recovery production. The technology is designed for long-term use, reducing maintenance costs. It also offers higher efficiency and power handling capability than other technologies. Overall, this approach decreases research and development time and upfront implementation cost.

Problems solved by technology

In fact, it is design for a long term use, increases reliability and decreases maintenance in the long run by having less radiating devices or attachments.

One of the challenges is to have a heating and recovering system that has the flexibility to fit through the Casing Borehole and reach to the desired depth of the well.

These openings could put a stop on using big pipes bigger than 5 inches in diameters and the space is very limited to maneuver in 12,000 feet below the ground surface.
