Achieve Excellence in PFO Analysis on Water Injectors
We provide services in well test design and analysis on all types of injection wells. We help you to obtain the best quality data and interpret injection shut-ins. We can also re-analyze old data or challenge previous interpretations.

Injection PFO Analysis

Why testing injection wells ?

  • It is challenging to understand the performance of a water injection well due to changes in open fracture size with injection pressure, due to possible changes in water temperature (produced vs seawater) and in reservoir pressure, and due to changes in frac conductivity and damage.
  • Have a cost-effective surveillance and diagnostic tool thanks to opportunistic shut-ins,
  • Understand which factors contribute to change in performance: frac dimension, frac closure, damage, etc…
  • Ensure water injection containment in reservoir and no excessive frac growth.
Well test analysis is one of the best tools to understand and monitor the performance of water injectors (and we are not biased…)
water injection wells
Each opportunistic shut-in could be analyzed -provided enough resources and expertise- to understand and monitor well and reservoir performance over time, and detect the causes of performance deviation. Much more information could be extracted and learnt from analyzing your data.


in addition to services on production wells:
  • Monitor and improve understanding of injection well performance.
    (multiphase flow, changing open fracture size, long transient response)
    • Detect water/oil interface and cold water front,
    • Monitor fracture size, increase in damage, impact of temperature and pressure,
    • Detect and understand fracturing events,
    • Ensure no excessive frac growth and containment in targeted layer,
    • Assess impact of produced water, cold water flush, stimulation and other interventions.
  • Understand causes of performance deviation
    • Detect frac closure, a receding frac height, increase in damage, blockage, sand fill, etc…
  • Review previous analysis and re-interpret pressure data using latest tools and techniques.

Why testing wells ?

Exploration, appraisal, development

  • Confirmation of discovery and productivity
  • Clean-up and rate measurement
  • Large volume fluid sample
  • Well and reservoir performance
  • (skin, KH, Pi, heterogeneity, boundaries)
  • Reservoir connectivity & proven volume
  • Flow behaviour around wellbore
  • Large scale of investigation (100-1000s ft)

Well testing in exploration and appraisal could point out to reservoir compartmentalization problem. Knowing this type of problem would prevent a field development train-wreck and huge financial losses.

Production and injection

  • Use of opportunistic shut-ins
  • Track permeability, skin, reservoir pressure
  • Monitor performance over time
  • Understand performance deviation
  • Assess well intervention
  • Quality control rate measurement

Other alternative ?

No other alternative to:

  • obtain large fluid sample
  • evaluate permeability over large distances (~100s-1000s feet),
  • assess well damage (skin)
  • investigate connectivity over large volume

Why using our services?

Global experience from Explo to Production

Extensive experience from exploration to production in all types of wells and reservoirs worldwide, in particular North Sea (UK and Norwegian sectors), GoM, Brasil, Azerbaijan, Algeria, Angola, Canada, Egypt, Oman, Jordan, Indonesia, etc…

Expertise in deconvolution

We have expertise in deconvolution.

Deconvolution is a great asset for your team. It helps to improve the understanding of the pressure data, refine initial pressure and add reservoir insights. While deconvolution is not new, it is often misused in the industry.

We are also dedicated to coaching you with deconvolution.

Dedicated to you!

We can act as your team well test expert, provide a 2nd review or simply reduce your expert’s workload.

We can review data from your shut-in or active wells with or without downhole gauges.

Maximum value

With costly and rare shut-in pressure data, don’t compromise on its interpretation.

We guarantee to provide more value out of your data. Let’s try a quick review of your existing design or interpretation and we’ll send you our comments.
