Do you use every production shut-in as an opportunity to learn ?


Do you have the resources and expertise to do this for each of your wells? 
Thanks to downhole gauges, about 95% of production PBU tests should come from opportunistic shut-ins. Do you analyze and extract information from all these “free” PBU tests ? 
If needed, we can provide you some support here.

Why analyzing production shut-ins ?

Baseline initial PBU tests help to define the initial well performance and to assess completion performance in a post well review. It is worth mentioning that 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.
Opportunistic production shut-ins are a great surveillance and diagnostic tool. Analysis of these “free” data helps you to monitor and predict well and reservoir performance over time, to QC the rate measurement and the allocation process, to detect and understand performance deviation and assess the true impact of a well intervention.


We can help you !

We can help you to establish surveillance best practices and test procedures so that you can obtain the best quality valuable shut-ins during production.
For a new well delivery, we can help to provide justification for downhole gauges (also in water injectors), to ensure your data processing system is adapted to pressure transient analysis and to design your planned shut-ins.
We can have a look at your shut-ins, help you monitor well performance over time, track reservoir pressure and perform multiphase flow analysis. We will be in a good position to detect and understand well performance deviation and give you recommendations on data acquisition during a well intervention.


Finally, we can re-interpret production data using the latest techniques and tools (including deconvolution). This may be useful to re-assess the field potential or simply understand further your well and reservoir performance.

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.

Get a 2nd opinion

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?
