Where to Deploy THOR for Maximum Impact?
Unlocking the Full Potential of THOR’s Downhole Heating Technology
THOR, Cavitas’ targeted downhole heater, is revolutionising Enhanced Oil Recovery (EOR) by applying low-carbon thermal energy exactly where it’s needed most – whether at the well’s perforations or above the perforations below the pump. But where should you deploy THOR for the best results?
THOR Over Perforations: Maximising Oil Production
For the greatest impact, THOR should be placed over the well’s perforations, directly heating the near wellbore. This reduces the pressure drop into the well tubing, significantly increasing flow and in some cases, more than doubling production.
✔ Minimised heat loss → Up to 80% Lower carbon footprint & fuel costs than topside heating
✔ Viscosity reduction → Enhanced production and flow at topside
✔ Reduced bottomhole flowing pressure → Increased drawdown & production
✔ Reservoir expansion → Heat penetration up to 15m, pressure influence up to 30m
✔ Skin removal → Eliminates near-wellbore waxes & emulsions
✔ Water cut reduction → Improved mobility ratio for better recovery up to half water cut
THOR Above Perforations: Enhancing Pump Efficiency
THOR is also highly effective above the perforations, just below the pump, delivering key benefits:
Flow assurance → Prevents wax and asphaltene buildup
Pump efficiency → Increased efficiency from 20% to 77%, improving flow and pump reliability
Lower bottomhole flowing pressure → Enables greater drawdown
Emulsion reduction → Faster topside separation & processing
By tailoring THOR’s placement to specific well conditions, operators can unlock its full potential by boosting production, enhancing efficiency, and reducing environmental impact.
