EHTM
Efficient Heat Transfer Mixer
Downhole steam mixing that turns heat into production.
EHTM is a fit-for-purpose downhole mixer that combines injected steam with formation fluids in a high-turbulence swirling chamber—transferring heat efficiently, lowering viscosity and friction, and increasing well productivity in heavy and extra-heavy oil operations.

Downhole detail
Inside the downhole mixer.
Steam is delivered from surface through the wellhead and directed into the EHTM. Inside the tool, accelerated steam drives a high-turbulence swirling mix that transfers heat rapidly into produced fluids. The swirling flow pattern increases formation-fluid inflow into the wellbore. The resulting energized mixture travels to surface with lower viscosity and reduced friction losses—raising productivity.
- 01
Steam inlet
Steam from the surface source enters the tool through the production tubing path.
- 02
Tangential nozzle
Steam is accelerated to high velocity, establishing the energy that drives the mixing process.
- 03
Mixing chamber
High-velocity steam creates intense turbulent swirling flow for rapid, efficient heat transfer.
- 04
Swirling-powered ports
The swirling flow establishes a localized pressure differential that increases formation-fluid inflow into the tool.
- 05
Diffuser section
Flow is stabilized and pressure is recovered as the mixture prepares for lift to surface.
- 06
Energized mixture
Heated, mixed fluid moves upward with lower viscosity and friction—supporting higher production rates.
- 07
Anti-erosion tip
A reinforced tip protects the assembly in abrasive downhole conditions for durable continuous operation.
