Validate sealing performance of cemented annuli Annular flow and sustained annulus pressure due to poor cement is a prevailing industry concern. But cement evaluation techniques only look at cement condition, not its sealing performance.   Cement Seal Integrity evaluates the seal performance of cemented annuli and reveals the presence of annular flow throughout the well system.   Delivered by our True Integrity system using the Chorus (acoustic) platform; Cement Seal Integrity provides the insights needed to restore and ensure annulus integrity.   Cement Seal Integrity is used routinely as a proactive measure to validate annulus integrity during well construction. Adopting a proactive approach complements traditional cement evaluation techniques to deliver a more secure well and avoid costly future problems.

The case also shows the sensitivity of Chorus over a temperature response, which demonstrates how effective the Chorus can be in location of minor cement channeling and reservoir activity.

Evaluate tube integrity of primary tubulars Production tubing and casing need to connect reservoirs to the surface safely and productively. Tracking the condition and wall thickness of primary tubulars is essential to maintaining a secure well.   Primary Tube Integrity provides the same accuracy advantages of Multi Tube, tailored for the production tubing or primary casing barrier.   Powered by our True Integrity system using the Pulse (electromagnetic) platform; Primary Tube Integrity delivers accurate wall thickness data – even if you have scale.   Primary Tube Integrity, if used routinely, can support your ongoing integrity management programme, or in a targeted fashion to investigate a specific integrity breach.   Our ability to reveal actual wall thickness and external defects makes it the ideal complement to conventional caliper type investigations.

Seamless digital workspace where our analysts transform data into critical insights Using a common, cohesive platform for data integration, processing and analysis is the industry standard, and there are several powerful solutions available in the market. But none have been custom-built to look at wells the way we do, or work with through-barrier technology the way we can.   Until now.   Maxim software is the backbone of our diagnostic systems and provides a seamless workflow from planning to processing, to products.   Our analysts use Maxim to develop and optimise diagnostic programmes and refine techniques. Then they use Maxim to process data and model results which they visualise and analyse to develop the critical insights that form the basis of our products. Maxim architectureProgrammes & methodsProgrammes & methodsProcessing & modelingAnalysis & interpretationProducts Our approach Rather than focusing our efforts solely on the tool, we recognise that it takes more than the tool to deliver accurate diagnostic answer products. It takes a diagnostic system supported by a digital platform.   The accuracy of each step has a knock-on effect on the overall accuracy of the diagnostic answers. Unlike other oilfield service companies, each of these steps is completed in-house, using our own intellectual property which builds on more than 20 years’ experience in the through-barrier diagnostics market.   Maxim is the digital workspace that combines each step in both the True Flow and True Integrity systems. Pedigree 20 years of building knowledge and expertise in performing through-barrier diagnostics in thousands of well systems globally. TGT is the category leader with more than 200 scientists, mathematicians, engineers, and analysts specialising in through-barrier diagnostics.

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. Pulse architectureProgrammes & methodsTools & measurementsProcessing & modelingAnalysis & interpretationProducts 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 Pedigree 10 years of pioneering scientific research, ingenuity and direct field experience in applying electromagnetic diagnostics to thousands of well systems globally.

Pulse family Our Tube Integrity products rely on the Pulse, Indigo and Maxim platforms to deliver an accurate assessment of tube condition. Depending on the product and its application, we utlise a specific combination of Pulse sensors to achieve the desired diagnostic objective. Each sensor is designed to energise certain tubulars or ‘barriers’ and is arranged in the Pulse tool string used to survey the well.     We deploy a range of Pulse variants according to the number of barriers to be surveyed. Pulse1 is optimised to deliver ‘true wall thickness’ measurements of production tubing in eight sectors, with complete all-around sensing of tube wall condition. And for simultaneous assessment of multiple barriers, Pulse2, Pulse3 and Pulse4 are utilised for two, three and up to four barriers respectively. The multi barrier variants can be combined with Pulse1 for a more detailed assessment of the well completion.

Acoustic sensing and analysis platform, revealing flow throughout the well system Fluid flow in the well system creates a rich spectrum of acoustic energy that penetrates the surroundings. This acoustic wave is encoded with information about the type of flow, and its location.   But well systems aren’t ‘recording studios’. Sound frequency and intensity vary from barely imperceptible to deafeningly loud. Noisy interference can drown out important signals. And even if the acoustic wave form is captured faithfully, the link between flow and acoustics is so complex that translating it into reliable flow information is often beyond the reach of ordinary systems.   Chorus is not a tool nor is it any ordinary platform. It delivers incredible resolution and fidelity across the widest spectrum of useful acoustic energy.   Chorus is part of our True Flow System and is used to locate and characterise flow for our True Flow products. Chorus is also part of our True Integrity System and is used to validate sealing performance (confirming there are no leaks) in well system barriers in our True Integrity Seal products. Chorus architectureProgrammes & methodsTools & measurementsProcessing & modelingAnalysis & interpretationProducts 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 then filter, process and model the data into tangible answers. Therefore, 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.   Chorus is our acoustic platform and when in the hands of our engineers and analysts, can precisely locate any kind of flow event within the entire well system.   Chorus platform follows a logical workflow where each part of the framework works to reveal a more complete picture of your flow within your well system.

Multisense functionality completes the diagnostic picture in real-time Delivering the right information at the right time is fundamental to successful diagnostics. Measurements must be accurate and appropriate for the task, particularly when you want to see more.   Many companies use mass produced, off-the-shelf tools to make and convey well measurements. But not all follow our exacting design standards.   That’s why we make our own.   Indigo is a seamless ‘silent’ platform of wellbore sensors, memory, communication and power modules that have been engineered to synchronise perfectly with TGT’s Chorus, Cascade and Pulse technology. The result is enhanced measurement accuracy and a more complete picture.   Also, Indigo enables memory mode and real-time operation. This capability provides extra flexibility and boosts the efficiency of through-barrier interventions.
