Achieve Excellence in Well Test Analysis on Oil and Gas Producers
We provide services in well test design and analysis on all types of wells and reservoirs worldwide. We help you to obtain the best quality data and interpret production shut-ins. We can also re-analyze old data or challenge previous interpretations.
Production PBU Analysis
Why analyzing PBUs from production wells?
Define initial well performance and assess completion performance in a post well review (well damage, skin elements, permeability, connectivity and initial pressure). Due to the transient response, a combination of rate and pressure measurement points doesn’t define well productivity, in particular for a vertical well in low-mid permeability reservoir, a fractured well or a horizontal well.
Have a cost-effective surveillance and diagnostic tool thanks to opportunistic shut-ins,
Monitor and predict performance over time,
Detect performance deviation and understand its causes,
Assess well intervention,
Quality control rate measurement,
And much more…
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.
Services in Oil and Gas Production
Provide surveillance best practices and test procedures for best quality valuable shut-ins.
For new well delivery:
Provide justification for downhole gauge and planned shut-ins,
Ensure the data processing system is adapted to pressure transient analysis,
Design planned shut-ins to acquire valuable data with minimum duration.
Use every shut-in as an opportunity to learn:
Evaluate reservoir and well production efficiency and completion strategy,
Monitor well performance over time: damage, effective permeability, perforation height, horizontal flowing length, frac length and conductivity, pressure support problems, etc…
Track reservoir pressure to monitor connectivity and recovery process,
Perform multiphase flow analysis.
Understand performance deviation:
Detect water front, predict water breakthrough and support lab-derived relative permeability curves,
Detect fluid breakout before the situation becomes irreversible,
Spot blockage, sand fill, etc…
Avoid a costly well intervention and get a more efficient treatment to successfully target the problem.
Design data acquisition strategy during an intervention and assess the impact of the well treatment while minimizing the intervention and shut-in time.
Re-interpret pressure data using latest tools (including deconvolution) and techniques.

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)
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.
- 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 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…
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 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 employees from national companies, independents, majors and more “generalist” service companies.
