Pioneering electromagnetics delivering highly accurate tube integrity diagnostics

The miles of metal tubes that form the backbone of your well system are fundamental to its integrity. Tracking the condition and wall thickness of all tubes is essential to maintain a secure well.

 

The ‘electromagnetic signature’ of each tube contains information about the wall thickness, but extracting this accurately pushes the boundaries of electromagnetics, 3D modeling, and wellbore measurements to the furthest limits.

 

That’s exactly what we’ve managed to achieve with Pulse.

 

Pulse powers our True Integrity Tube products to accurately assess up to four concentric tubes from inside the wellbore. And unlike conventional systems, it works in all completion types, including dual string and corrosion resistant alloys.

Processing & modeling

Our model solves Maxwell equations which help transform raw data into accurate wall thickness measurements in all well geometries, including dual string completions, so you know your well’s condition from top to bottom.

Our approach

We recognise that delivering accurate diagnostics requires not only the highest fidelity measurements, but also a system-based approach. It is important to have the best sensors and measurements, but it also important to use them in the right way and then to filter, process and model the data into tangible answers.

 

We pursue a diagnostic system approach where multiple platforms come together, bringing their own unique diagnostic capability to be used in the framework of the proven workflow.

 

Pulse is our electromagnetic platform, providing accurate barrier-by-barrier assessment of up to four concentric tubulars from a single through-tubing deployment.

 

Pulse platform is part of our True Integrity System and is used to evaluate the metal condition of tubulars throughout the well system. Pulse supports the diagnostic answers for the True Integrity Tube products
