Well Integrity Data Analysis

Analysis of Well Barrier Structural Integrity and Cement Properties

We are experts in well integrity data analysis and for nearly 30 years we have been delivering robust cased hole data analytics solutions to operators and service companies all over the world.

Well integrity evaluation means getting the full picture of your well’s barrier performance. It is about understanding the structural integrity of your tubing, casing, liners and cement, to ultimately manage risk, extend operating life and optimise the management of your wells across their lifecycle.

Our experience in well integrity data analysis is second to none, perfected over many years analysing data acquired by multifinger calipers, magnetic thickness, leak detection and ultrasonic technologies.

Well integrity is becoming more critical than ever, as wells remain in production for longer or are repurposed for CO2, gas storage and other applications. Our analysts fully understand how wells can become unintended migration pathways for fluids out of the reservoir or gas cavern.

Our well integrity data analysis solutions help clients:

Multifinger Caliper Analysis

ANSA can work with any caliper dataset, no matter the technology supplier.

We process, analyse and interpret multifinger caliper data to present valuable insight into well accessibility issues. This is achieved through direct measurement of smaller than expected IDs, and when evaluated with advanced data analytics methods, we can reveal the tubular’s true 3D geometry.

Whether evaluating deposition, drilling wear, or plug and packer setting optimal positioning, we offer our clients detailed analysis to quickly identify integrity issues and making qualified decisions about appropriate remedial action.

Magnetic Thickness Analysis

We can advise you on your magnetic logging strategy, how to best combine it with other technologies and ultimately help you get the information you need about the condition of your well barriers.

We are highly experienced in processing and analysing data from a variety of magnetic thickness tools. Whatever the technology in use, we can add value to your operation.

This family of logging tools allow the evaluation of your asset’s multiple barriers without the need of pulling the tubing. Being able to see through scale and deposits, ANSA can evaluate the condition of the 1st, 2nd and 3rd barriers from data acquired in a single run in-hole.

Magnetic Thickness Analysis

Ultrasonic Analysis

When you need the most accurate results from your ultrasonic data – to conduct crucial burst and pressure calculations or to allow for time-lapse studies – we can deliver expert analysis irrespective of which technology or vendor was used to acquire the data.

We have the know-how to assess data acquired by ultrasonic technology and provide our clients with high accuracy ID and thickness measurements of both tubing and casing, to reveal issues such as corrosion, mechanically induced damage and deformation.

Cement Evaluation

Our wealth of experience with advanced data analytics techniques can get the most out of your radial bond and ultrasonic cement evaluation datasets, from planning through to final delivery.

Radial cement evaluation tools deliver an accurate evaluation of cement distribution behind casing by providing the precise location of partial bond and channeling around the full circumference of the casing. We give you the confidence to make informed decisions quickly, from the individual log curves to azimuthal images (maps) of cement quality and expert VDL waveform analysis.

ANSA’s state-of-the-art diagnostics techniques give you the most accurate interpretation of your datasets.
