Announcement Two of the engineers behind WellCat are joining eWellbore

Issa Kalil and Bill Taylor, currently with Altus Well Experts and previously with Enertech who created WellCat, will soon be joining eWellbore.

Today's reality

Well integrity has traditionally been managed after problems occur

For decades, well integrity has relied on inspections, testing, and engineering judgment throughout the life of the well. Yet there is no Integrity Safety Factor (ISF) to measure and track degradation of well integrity before failure occurs.

Once signs of an integrity problem appear, it's already too late. Sustained casing pressure means leakage of pipe or cement has already occurred. And leaks get worse with time, resulting in costly intervention, deferred production, and increased environmental risk.

  1. 01

    Well integrity is assumed at design

    Operating loads, however, can differ significantly from design assumptions. Once operations begin, changes in well integrity often remain hidden until anomalous pressure, a leak, or another sign of degradation appears.

  2. 02

    Inspection detects a potential issue

    The well may be shut in while engineers evaluate the issue, leading to downtime, deferred production, and added cost.

  3. 03

    Investigation evaluates the cause

    Engineers analyze available data to understand the likely cause and assess the potential impact on safety, the environment, and continued operation.

  4. 04

    Repair restores operations

    The well returns to service, but the underlying integrity challenge may remain. The cycle repeats until the next issue is detected.

↺Repeat, well by well, for the life of the field

It's time to stop reacting to failures and start measuring well integrity. More safety. Less cost.

Well integrity · measure

The first measurable engineering metric for well integrity

Engineers have long relied on proven methods to measure strength, pressure, and fatigue. Until now, there has been no consistent way to measure and benchmark well integrity itself.

eWellbore develops engineering software and provides consulting services for well design and integrity management, making well safety measurable, trackable, and manageable throughout the life of the well—before something fails.

Ovality drives integrity.

eWellbore closes that gap with the Integrity Safety Factor (ISF), the first metric for measuring well integrity. Pipe, cement, and operational ISFs are measured, monitored, and maintained at acceptable values throughout the life of the well.

Rooted in the engineering methods that helped shape today's well-design standards.

The cost of waiting until something goes wrong

When the root cause of well integrity problems remains unresolved, the consequences extend beyond the immediate failure. Asset damage, environmental liability, litigation, and reputational harm can far exceed the direct costs of repairs, lost production, and downtime.

The measurement gap

Every other failure mode has a number

Strength, pressure, and fatigue each have a defensible engineering metric. Until now, well integrity has been the exception. eWellbore gives integrity the same footing.

If you cannot measure well integrity, you cannot keep score using the 3Ms: Measure. Monitor. Maintain Integrity.

Without a score, there is no way to know whether integrity is improving or deteriorating.

One engine

One engine. Two digital twins.

eWellbore's engineering software is built around a single physics engine that powers two integrated digital twins. The WellDone twin simulates the planned well based on assumed conditions, while the WellGrit twin simulates the live well in real time under actual conditions. Engineering data, including ISFs, flows continuously between the two digital twins, creating a closed-loop learning system for well integrity.

Design twin

WellDone

Advances well design using advanced multi-string stress analysis and multi-well thermal analysis, providing a more accurate representation of complex well behavior than traditional single-string, single-well methods.

  • Composite multi-string stress analysis, including cement
  • Multi-well thermal analysis
  • More accurate modeling of complex well behavior

Imagine trying to unscrew an oval pipe, seal oval threads, and keep the surrounding cement from cracking. Ovality drives integrity. That’s the type of real-world behavior WellDone is designed to model.

Live twin

WellGrit

Continuously evaluates the live well against the designed well. ISFs are measured and monitored across pipe, cement, and operations, helping operators identify degrading well integrity before failure occurs. Works with the data and downhole instrumentation you already have

  • Real-time ISFs
  • Alerts when integrity falls outside safe operating thresholds
  • AI-assisted what-if analysis to maintain integrity
  • Recommends the best course of action for Safe-Load Management

Together, WellDone and WellGrit transform well integrity from a design assumption into an actionable engineering metric. Traditionally, increased safety comes at increased cost. WellDone and WellGrit improve safety while delivering potential cost savings of 10% or more through fewer repairs, less downtime, and reduced legal and environmental exposure.

Joint Industry Project

Help define the future of well design and well integrity management

The Joint Industry Project brings together operators, suppliers, and service companies to validate, refine, and establish the Integrity Safety Factor (ISF) as the next benchmark for well integrity while significantly advancing the technical capabilities of WellDone and WellGrit.

Participants help shape new capabilities, establish industry benchmarks, and gain early access while evaluating their own well portfolios.

How well integrity is evolving

The evolution of well integrity mirrors what happened with road travel. Maps established the route, digital maps made planning easier, and GPS introduced real-time guidance based on actual conditions.

If WellGrit is the GPS, then WellDone is the digital map.

Just as GPS transformed navigation from static planning to real-time guidance, WellGrit transforms well integrity from periodic inspection to real-time management.
