What is a Hot Oil Flushing Unit?

A hot oil flushing unit (also known as a well flushing truck or wax removal truck) is a specialized oilfield service vehicle designed to heat crude oil or water to high temperatures and pump it under pressure into oil wells. This process effectively melts and removes paraffin wax deposits, restoring well productivity and flow efficiency.

Vance Petroleum's hot oil circulation trucks are engineered with precision-controlled heating systems, heavy-duty triplex plunger pumps, and full PLC automation — making them the most reliable wax removal solution for onshore oilfield operations globally. Explore our full range at vancepetro.com.

How It Works — Working Principle

Step 01

Medium Loading

Crude oil or water loaded into onboard storage tank

Step 02

Heating Phase

Diesel burner heats medium to target temperature via coil heater

Step 03

Pressurized Pump

Triplex plunger pump pressurizes and delivers hot medium into wellbore

Step 04

Wax Dissolution

High-temp medium dissolves paraffin deposits in tubing and wellbore

Step 05

Return Circulation

Dissolved wax carried to surface, medium recycled for continuous operation

Result

Well Restored

Flow restored, production rate normalized, well back in optimal operation

Selection note: confirm the exact model, operating envelope, test conditions and included equipment in the supplier data sheet. Published maxima are not necessarily simultaneous ratings. Certification, delivery, warranty and service commitments must be confirmed for the quoted configuration.

Applications

Versatile Application Scenarios
Across Global Oilfields

From remote desert operations to offshore platforms, our hot oil flushing units deliver reliable performance in every oilfield environment.

PRIMARY USE

Paraffin Wax Removal

Most common application. High-temperature flushing medium melts and flushes paraffin deposits from tubing, casing, and wellbore, restoring flow to full capacity.

Effective on heavy & light paraffin deposits
Single pass or circulation mode
Suitable for vertical & deviated wells

WORKOVER

Well Killing & Workover

Pump hot fluid into the wellbore to establish hydrostatic pressure for safe well-killing operations prior to workover, intervention, or maintenance activities.

Precise pressure and flow rate control
Compatible with kill fluid formulations
Fast deployment to rig site

PIPELINE

Pipeline Thermal Treatment

Inject hot oil or water into surface pipelines and flowlines to thaw frozen sections, remove wax plugs, and restore full flow capacity across gathering networks.

High flow rate for long pipeline sections
Rapid thaw in sub-zero environments
Minimal disruption to production

DOWNHOLE

Downhole Scale Removal

Thermally assisted chemical treatments to dissolve and flush scale, asphaltene, and other mineral deposits from perforations, screens, and downhole equipment.

Enhanced chemical reaction efficiency
Works with acid or chelant systems
Reduces mechanical intervention frequency

HEAVY OIL

Heavy Oil Cold Start

Preheat wellbores and surface equipment in cold climates or after extended shutdowns to reduce crude oil viscosity and enable safe restart of heavy oil production wells.

Operates in -40°C arctic environments
Rapid viscosity reduction
Prevents pump rod freeze-up

CEMENTING

Cementing & Plug Jobs

Support cementing operations by providing accurately metered hot fluid displacement, spacer fluid heating, and plug bump confirmation pumping services on demand.

Accurate volume metering
Compatible with cement spacer fluids
Adjustable rate from 5–60 m³/h

Global Deployment

Proven Performance Across International projects

Our hot oil flushing units have been successfully deployed in diverse climatic and geological conditions — from the frigid oilfields of Siberia and Xinjiang, to the scorching deserts of Iraq, Kuwait, and North Africa, and the humid offshore environments of Southeast Asia.
