Paraffin Deposition Treatment

A new standard in production chemicals, driven by expertise and a commitment to service.

Flow Assurance & Production Stability Programs

Paraffin deposition is one of the most frequent causes of production decline and mechanical failures in Western Canadian oil wells. As produced fluids cool and pressure changes occur during lifting and transport, wax molecules fall out of solution and attach to metal surfaces throughout the system.

Over time this restricts flow, increases loads, and leads to pump inefficiency, repeated hot oiling, and unplanned downtime.

Echelon Chemicals approaches paraffin control as an operational reliability issue — not simply a chemical supply problem. Our programs follow a structured process: Identify → Remediate → Maintain.


Why Paraffin Forms

Wax Appearance Temperature (WAT)

Wax precipitation begins when produced fluids fall below the Wax Appearance Temperature (WAT). This commonly occurs in:

  • Rod pumped wells
  • Long or cold flowlines
  • Declining fluid level wells
  • Gas breakout zones
  • Medium and heavy crude reservoirs
  • Winter operating conditions

Once initial deposition occurs, buildup accelerates as wax traps solids, scale, and asphaltenes — turning a minor issue into a recurring mechanical problem.


Common Field Indicators

Paraffin problems rarely appear all at once. They usually show up as gradual operational changes:

  • Production decline
  • Increasing polished rod load
  • Rising motor amperage
  • Pump tagging fluid
  • Sticking rods
  • Frequent hot oiling
  • Separator wax accumulation
  • Flowline pressure increase

These symptoms indicate restriction is developing somewhere in the system.


The Echelon Approach

Our programs are designed around the behavior of the well — not just the chemistry. We apply the Identify → Remediate → Maintain process to restore flow and prevent recurrence.

Identify — Determine the Deposition Mechanism

  • Temperature profile
  • Production rates
  • Fluid composition
  • Lift method
  • Deposition location
  • Mechanical constraints

This establishes whether the issue is precipitation, transport failure, or accumulation after initial nucleation.

Remediate — Remove Existing Deposits

  • Solvent treatments
  • Batch chemical cleanouts
  • Targeted placement programs
  • Surface equipment cleaning
  • Assisted mechanical removal

The objective is restoring unrestricted flow prior to preventative treatment.

Maintain — Prevent Recurrence

  • Paraffin inhibitors — prevent crystal adhesion
  • Dispersants — keep wax moving in the fluid stream
  • Carrier systems — place chemistry at the deposition point
  • Continuous injection — stabilize operating conditions
  • Capillary injection and downhole placement options

The goal is stable operation — not repeated intervention.


Operational Benefits

  • Reduced hot oiling frequency
  • Improved pump run life
  • Lower operating costs
  • Stabilized production rates
  • Fewer service calls
  • Improved fluid handling at surface

Where Programs Are Applied

  • Rod pumped wells
  • PCP wells
  • Gathering systems and flowlines
  • Cold weather operations
  • Medium and heavy oil production

Technical Consultation

If you are experiencing recurring wax accumulation or increasing loads, we can review operating conditions and recommend an approach based on the Identify → Remediate → Maintain process.

Request Field Review
