The experience to do the job

InnoTech Alberta has more than 30 years of chemical flooding expertise, ranging from lab-scale evaluations to successful field implementations. We can offer extensive knowledge to assist with your chemical flood project.

Specialized testing and equipment

InnoTech's facilities and expertise allow us to support the design of a chemical flood and predict its potential for your field. Our skills and equipment include the following:

  • Phase behaviour tubes for microemulsion flooding
  • Spinning drop IFT measurements
  • Adsorption tests (static and flow-through)
  • Micromodel floods
    • displacement study
    • rapid screening process
  • Corefloods
    • demonstrate recovery efficiency under field conditions
    • Simulations
    • lab-scale
    • field-scale
  • Economic feasibility

Unique Spinning drop IFT

InnoTech owns a computer controlled DataPhysics SVT-20 spinning drop tensiometer.

Quicker turnaround, lower cost

With quickly removable capillaries and rotational speeds of up to 20,000 rpm, interfacial tension (IFT) measurements can be performed in minutes, saving you time and money.

Using an advanced integrated image analysis system, the tensiometer can simultaneously do several automated methods of droplet analysis.
IFT measurements range from 10-6 mN/m to 72.9 mN/m, and are easily exported to MS Excel.

As a tool to monitor surfactant breakthrough in the field, or as a means to screen injected chemical formulations, the SVT-20 is invaluable for EOR flood design and monitoring.

Implementing Chemical Floods

Field Implementation

  • Equipment recommendations
  • Operating strategies based on simulation
  • Chemical formulation
  • Injection and production strategies
  • Salinity gradient/mobility buffer (formicellar flooding) and interfaces

Field Assessment

  • Comparing production data against simulated prediction
  • Adjusting injection strategies to respond to field conditions
  • Upscaling from pilot to commercial application

Analysis of produced fluids

Analyzing the produced fluids of a chemical flood determines incremental oil recovery and provides an understanding of how efficiently the injected chemicals move through the formation. This information helps optimize the flood for greater economic return.

Field monitoring

  • Produced fluids (breakthrough analysis)
    • polymer concentration (automated method)
    • surfactant concentration (automated for specific types)
    • IFT monitoring of produced oil and water alkali
    • total dissolved solids (TDS)
    • specialty analysis
  • Injected volumes
  • Produced volumes (water and oil)
  • Injection and production pressures
