Cavitas Energy- Targeted Downhole Heating Specialist

Cavitas Energy- Targeted Downhole Heating Specialist

Formed in 2016, Cavitas Energy is a leading expert in downhole thermal applications. A UK based ISO 9001 registered engineering company, focused on providing innovative services and value adding solutions to the energy industries. The company’s technical team consists of experienced engineers and geoscientists who together provide innovative and tailored solutions to their expanding global client base.

Cavitas are best known for developing the world’s highest energy density downhole heater called THOR, with applications in viscous oils, flow assurance, natural gas, and low enthalpy geothermal. THOR provides reliable and controlled heat downhole, making viscous and waxy crudes act like easier to produce light oil, revolutionising development plans, lowering the carbon footprint and requiring less CAPEX for wells and facilities, all while increasing production.

Cavitas’ innovative downhole heater, named THOR, is revolutionising thermal applications whilst reducing the carbon emissions compared to traditional methods. THOR provides:

• In-situ near wellbore heating

• Up to 500% production increase in heavy oil

• Flow assurance in wax and asphaltene

• Increase pump efficiency and run life over 50%

• Restoring production in liquid loaded gas wells

• Unblocking pipelines and risers

Cavitas’ heater emits only 1.51 gC02/MJ during operation, which is around 20 times less than traditional thermal operations such as steam floods in Kern, California at 29.33 g/MJ. THOR’s high (90%) efficiency and targeted heat downhole also keep fuel costs low.

Over 40% of the global remaining oil is heavy, which is most effectively developed by thermal operations. THORs low carbon barrels could have a vast impact on the global goal of keeping Climate Change below 2°C.

Reliable Mechanical Downhole Heating

THOR’s mechanical design offers the highest downhole heat energy density on the market, up to 55 kW/m, which is 50-100x greater than typical electrical cable heaters. The tool itself is significantly shorter and lighter than alternatives, which is easier to deploy and retrieve.

THOR’s ingenious mechanical design avoids the reliability issues that plague ‘Electric Cable Heaters’, e.g. hot spots at splices. THOR’s fully sealed design avoids free gas and solids shock loading, a key failure mechanism of pumps.

The downhole tooling requires no maintenance on its 3-5 year run life and can be monitored remotely, where traditional methods will require Maintenance Technicians on site 24/7.

The small topside footprint of a VSD, Transformer and Junction Box make it ideal for offshore or remote wells.

The flexible rental model can allow Operators to receive a return on investment in 50 days or less.

Cavitas’ active design team and innovative spirit means THOR can be fully customised to suit all requirements that the operator has. Fully unlocking the potential of their wells in an environmentally friendly way.
