The Point®systemBetter well integrity
Wireline
Protect your investment
Now more than ever, well integrity is a global concern. Figures highlight that integrity failures affect at least 40% of wells worldwide. Losing integrity can endanger lives, pollute the environment, and ruin reputations. Production is also affected. Restoring integrity can mitigate these risks, improve production and deliver better returns.
Proactive integrity management
Proactively monitoring the ongoing integrity status of your wells and being able to diagnose an integrity failure quickly, accurately and completely, ensures safe, reliable and productive operations, while keeping interventions and costs to a minimum.
Combining a suite of well–diagnostic technologies and protocols with the knowledge and expertise of our well–integrity specialists, the Point system makes it possible to validate the integrity status of wells and locate failures when they occur.
The Point system has already been proven in over 2,000 successful operations worldwide – and our Point engineers and analysts work with you at every stage to design, deploy and evaluate the most effective diagnostic surveys for your wells.

A systematic approach
The Point system includes seven powerful diagnostic programmes that enable a proactive and systematic approach to integrity management.
Investigate all barrier leaks and a single flowpath
A standard programme to investigate straightforward integrity failures.
Proactive or when SAP is suspected or observed in the A-annulus.
Targets the primary barrier tubing and A-annulus.
Uses existing data or high-precision instruments to measure static and dynamic digital pressure profiles.
Engineer or analyst provides a brief report outlining integrity status, characterising SAP, with estimated inflow leak rate for the A-annulus.
Investigate all barrier leaks and a single flowpath
A custom programme to investigate complex integrity failures.
Proactive or when SAP is suspected or observed in a single cemented annulus.
Targets all barriers and a single cemented annulus.
Uses high-precision instruments to measure static and dynamic digital pressure profiles.
Senior analyst provides a comprehensive report detailing integrity status, characterising SAP, with calculated inflow leak rates for affected annuli.
Investigate all barrier leaks and multiple flowpaths
A custom programme to investigate highly complex, multiple failures.
Proactive or when SAP is suspected or observed in multiple cemented annuli.
Targets all barriers and multiple cemented annuli.
Uses high-precision instruments to measure static and dynamic digital pressure profiles.
Injectivity testing may be performed to reveal more complex failures.
Senior analyst provides an advanced report detailing the integrity status, characterising SAP, with calculated inflow leak rates for affected annuli.
Locate primary barrier leaks
A standard survey to diagnose straightforward integrity failures.
Follows a CheckPoint/A10 investigation, or when SAP is observed in the A-annulus.
Targets primary barriers and A-annulus.
Uses a LeakPoint/A10 logging platform.
Engineer evaluates data to define the failures and their precise location.
Leak locations are normally clearly visible in wellsite field logs.
Locate all barrier leaks
A standard survey to diagnose moderately complex integrity failures.
Follows a CheckPoint/A50 or /A70 investigation, or when SAP is observed in a single cemented annulus.
Targets each suspected barrier and annulus.
Uses a LeakPoint/A30 logging platform.
Analyst evaluates data to define the failures and their precise location.
Leak locations may be visible in field logs, or data may require further interpretation.
Locate all barrier leaks and a single flowpath
A custom survey to diagnose complex integrity failures.
Follows a CheckPoint/A50 or /A70 investigation, or when SAP is observed in a single cemented annulus.
Targets each suspected barrier and annulus.

Senior analyst evaluates data to define the failures and their precise location.
Following in-depth analysis and interpretation, a final report is typically delivered within 5 to 7 days.
Locate all barrier leaks and multiple flowpaths
A custom survey to diagnose highly complex, multiple failures.

CheckPoint®
Investigate barrier leaks and flowpaths from surface
Many operators realise that proactive integrity management pays dividends. Continuous integrity monitoring, or conducting routine integrity checks, provides the reassurance that critical well barriers are intact or an early indication of failure, enabling timely action to be taken before the problem escalates.
We’ve created CheckPoint as the first stage in proactive well integrity appraisal. Deployed at surface, CheckPoint is used routinely, both to validate integrity and in response to a loss of integrity, to reveal detailed clues about the nature and location of the failure in the well. And because CheckPoint is performed at surface, it does not expose the operator to the disruption, cost and risk associated with logging interventions. Even better, CheckPoint programmes are inherently straightforward, easy to mobilise, and low cost.
LeakPoint®
Locate barrier leaks downhole
Leaks can reduce a well’s performance throughout its life and cause serious safety, environmental and reputational issues. With legacy leak–detection methods such as temperature or acoustic noise logs, the reliability of diagnosis varies as results can be affected by leak rate and location. Low-rate or multiple leaks and leaks beyond the primary tubular are particularly challenging.
LeakPoint is able to expose leaks in the primary tubular and surrounding casings or completion equipment clearly, reliably and consistently. Unlike conventional methods, LeakPoint detection technology is sensitive to a wide range of leak rates and locations. Results are vividly clear and unambiguous– leak locations are revealed with pinpoint accuracy. And more complex leaks beyond the A–annulus can also be diagnosed – even while a well is flowing.
FlowPoint®
Locate barrier leaks and flowpaths downhole
Losing annular integrity is one of the most dangerous and potentially damaging types of well failure. Contaminated ground water and annular blowouts at surface are among the most feared potential outcomes. Despite advances in cementing, unwanted annular flow and sustained annulus pressure due to poor cement sealing is a prevailing concern for many operators. Diagnosing flow behind casing has challenged well engineers for decades, and the most commonly used annular diagnostic methods downhole only evaluate barrier condition– not barrier sealing performance.
Building on the capabilities of LeakPoint, FlowPoint can locate barrier leaks and map unwanted annular flowpaths throughout the well system, enabling it to diagnose the most complex multiple failure scenarios efficiently and comprehensively.
