Some digital pressure testing methods used in the oil and gas industry rely on predictive early data trends to draw conclusions about future performance. While these approaches may appear sophisticated, they often depend on assumptions that can be misleading. In safety-critical operations, the consequences of being wrong can be very dangerous.
At IPT Global, our approach is grounded in physics: how equipment actually behaves under pressure and an array of thermal variables. Our SureTec® PressureTesting Solution focuses on measurable system behavior rather than early-time trends and predictions, which provides greater assurance, protecting people, assets, and the environment.
Why Predicting from Early Data is Risky
During well control equipment pressure testing, a pressure decline can result from three distinct causes:
- A true integrity failure (a leak) – the condition the test is intended to detect
- The equipment stretches slightly under pressure
- Complex thermal effects as the system cools
Why is this a problem? Because all three occur at the same time, and their combined effects appear as a single pressure curve making interpretation more challenging than it first appears.
Many digital pressure testing tools attempt to determine a pass or fail by observing how pressure decline slows over time. However, thermal and elastic effects naturally dominate early behavior and always attenuate. This early stabilization can create the appearance of improvement even when a real leak is present.
In short, early-time prediction alone does not confirm integrity, but rather introduces uncertainty at precisely the point where certainty is required.
IPT Global’s Physics-Based Approach
Rather than predicting what might happen, IPT Global’s PressureTesting Solution models how a leak-free system should behave. We account for normal pressure changes caused by temperature and equipment expansion, establish a physics-based fingerprint for a healthy system, and evaluate subsequent tests against that baseline to identify true integrity failures.
Our focus is on delivering accurate, objective digital pressure testing results. In practice, that means fewer assumptions and clearer answers during the test itself. Instead of relying on trend-based prediction, we ask a more fundamental question: Does the observed behavior match that of a leak-free system?
Delivering Confidence When It Matters
A major offshore operator evaluated IPT Global’s physics-based PressureTesting Solution against a competing predictive pressure testing solution using real subsea BOP test data, including tests with confirmed visible leaks.
IPT Global correctly identified every known failure. The predictive solution, however, incorrectly passed multiple tests, including some with confirmed visible leaks.
A false pass, indicating equipment integrity when a failure exists, can expose operations to safety risks, environmental damage, unplanned downtime, and reputational harm.
Ultimately, when people, assets, and the environment are on the line, uncertainty should never be mistaken for insight. Physics-based analysis replaces assumption with understanding and delivers the confidence that safety-critical decisions demand.
