THOR | Thermal Heavy Oil Recovery

Downhole heating for viscous fluid wells to improve production and flow assurance

THOR: Cavitas’ Thermal Heavy Oil Recovery technology has been designed to address a global requirement for in-well Thermal Enhanced Oil Recovery (EOR) for use where conventional Thermal EOR is not effective, such as offshore.

THOR is suitable for deployment in injection and production wells, using thermodynamics to enhance production while limiting the build-up of waxes and scales. THOR heats fluids downhole as opposed to traditional topside methods where large energy losses occur. This greatly improves the energy balance.

Pro/con

Achieve Thermal EOR in previously discounted wells
Increase production rates
Mitigate waxes and asphaltenes
Increase recoverable reserves
Unlocks remote heavy oil
Reduce frictional losses
Improve artificial lift efficiency
Reduce carbon footprint via green energy options.
Suitable for casings of 5.25” or larger
Currently not field proven

Specification

Areas of Application Applications in both injection and production wells
Asset life extension THOR has been modelled to show that if utilized on greenfield heavy oil developments it can increase the productive life of the field by 9 or more years.
Enviroment THOR is less sensitive to water quality than some other forms of thermal EOR technology leading to the use of less chemicals and therefore environmental improvement.
IP Protection Cavitas has UK and International PCT patents for THOR pending.
Modelling The first step in any THOR project would be to work collaboratively to produce a reservoir EOR model.
Thermal conductivity THOR has a much higher energy density than comparable solutions. Generally in the 30-50kW per meter range.
Return on investment Our planned pilots show an ROI in the region of 50 – 200 days.
