Question 1 of 10
Deconvolution works best when:Correct
Question 2 of 10
Could we use a horizontal well model to match a deviated well ?Correct
Question 3 of 10
Is the match more important than the selection of the interpretation model ?Correct
Question 4 of 10
Why would we run seabed gauges during an appraisal well test ?Correct
Question 5 of 10
Why is it recommended to run multiple gauges in the tubing during an exploration and appraisal test?Correct
Question 6 of 10
Question 7 of 10
What is the impact of tides on the derivative response ?Correct
a decrease in derivative
Question 8 of 10
(click on the plot to enlarge)Correct
Question 9 of 10
Between the options below, what is the first thing you need to do when performing an analysis of an exploration well test:Correct
Correct! We would also have accepted the “Call TestWells” one…Incorrect
If you said “Call TestWells”, you’ve got an extra point.
Question 10 of 10
What are the main problems when using a multi-layer model to match the data ?Correct

Why testing wells ?
- 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)
- Use of opportunistic shut-ins
- Track permeability, skin, reservoir pressure
- Monitor performance over time
- Understand performance deviation
- Assess well intervention
- Quality control rate measurement
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?
Extensive and practical experience 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…
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.
We care and are 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.
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.
You already have a design or interpretation study but are not entirely satisfied or simply want to check if more value can be obtained at minimum cost?

We support geologists, petrophysicists, engineers from national companies, independents, majors and more “generalist” service companies.
