Case Study of Enhanced Oil Recovery Using Downhole Electric Heater in Cat Canyon Field, California

Abstract Downhole heaters are used to enhance the extraction of heavy, high-viscosity oils, which are challenging to produce using conventional methods. In addition, these heaters address some limitations associated with Underground Injection Control (UIC) regulations in California, particularly the stringent requirements for testing and identifying potential leaks in injection wells. Efficiency and Control: Downhole electric heaters (DEHs) are highly efficient, reliable, and easily controlled. They provide a consistent heat source that can reduce the viscosity of heavy oil, facilitating its flow and improving production rates.Complement to Steam Injection: DEHs can complement steam-based projects by enabling continuous production when steam injection is not feasible. They help lower the initial reservoir pressure, making it easier to manage the heavy oil production process.Improved Production Early On: Applying downhole electric heating early in the production process can maximize the recovery of heavy oil. This approach can be particularly effective in mitigating the limitations posed by UIC regulations, which may restrict certain methods of well stimulation. By reducing the viscosity of heavy oils and enabling more efficient extraction methods, downhole heaters play a crucial role in overcoming regulatory and operational challenges in California's heavy oil production. Integrating solar energy with downhole heaters offers an environmentally friendly solution. Solar panels can generate electricity to power the downhole heaters, providing a sustainable and cost-effective energy source. This approach can further reduce the carbon footprint of oil extraction processes while ensuring compliance with UIC regulations by limiting the need for traditional energy sources that may involve higher emissions or additional environmental impact. In this paper, we discuss a case study of Enhanced Oil Recovery (EOR) using Downhole Electric Heater (DEH) in a vertical well in Cat Canyon Field, California from planning phase to execution and monitoring. In addition, the integration of solar energy allowing long-term cost effectiveness is addressed.
