The Cereus Engine
Today, with limited capex available for new developments, it’s an economic imperative to get shut-in wells back online, to make sure maturing assets are safe and compliant, and to develop effective and affordable P&A programmes. Whether you’re an operator planning your next intervention or an oilfield service company looking to extend your portfolio, Cereus has a unique suite of plug-and-play tools utilising the Cereus Engine: systems that you won’t find elsewhere.
Cereus has developed the world’s first contact-free, direct measurement technique for well integrity, cement bond logs and P&A surveys that can be deployed through tubing and multiple casing strings – even in gas wells. Now you can:
Contact Cereus to discuss your oil and gas application, or explore our unique range of tools:
A compact, small-diameter production tubing inspection tool featuring significantly improved resolution and accuracy compared to standard, first-generation ultrasonic tools. Use it to identify downhole leaks and integrity issues. While providing a direct measurement using the Cereus Engine in the time domain and Acoustics Resonance Technology (ART) in the frequency domain, this contact-free technique avoids the potential for tubing damage associated with running mechanical tools such as multi-finger callipers.
Nusonix Inspect has been engineered to be smaller and lighter than existing ultrasonic tools, making it both quicker to use and cost-effective to run. A complete report of processed data will be available on site within the hour.
The system is ideal to rapidly validate the integrity of gas storage and CO2 sequestration wells.

Built on the same compact chassis as our workhorse Nusonix Inspect, this ground-breaking system features a unique transducer assembly set to revolutionize Cement Bond Logging. The new level of information captured by our Cereus Engine ultra-high-fidelity ultrasonics using time domain and Acoustics Resonance Technology (ART) in the frequency domain offers the capability not just to identify a bad bond but to directly quantify the size of any gap within the bond and the quality of the cement.
During the same run, crews can also inspect well casing for signs of corrosion at a higher resolution than existing industry standards – making it a light intervention option. And all of this will be possible while performing a direct measurement of internal diameter and wall thickness – offering significant job efficiency gains.

Nusonix MultiString is the tool that the oil and gas industry has been waiting for. For the first time it’s now possible to accurately measure casing corrosion and to log cement bonds in high resolution using the Cereus Engine in the time domain and Acoustics Resonance Technology (ART) in the frequency domain at the same time without the need to pull production tubing.
This unique functionality also adds the capability to evaluate the seal performance of a new generation of plug technologies and the potential to assess the integrity of multiple casing strings – paving the way for more cost-effective rig-less plug and abandonment operations.
