Migrating from iWIT to Wells Expert System

The Wells expert system of NEXUS is replacing the iWIT well integrity management software as the main Well integrity management software offering and Wood plans to end support for iWIT at the end of 2024.

Benefits

Migrating to the NEXUS Wells expert system from iWIT offers a number of direct improvements and benefits to you, including:

  • NEXUS Integrity Centre is developed on SQL Server, which means that you won’t be required to have an Oracle application available (which is the current database structure for iWIT).

  • Moving to the NEXUS IC system will provide you with the flexibility to either internally host the database as an on-premise application, or subscribe to a SaaS cloud-based system. IWIT currently only provides on-premise deployment options.

  • The NEXUS IC infrastructure allows you to subscribe to the Wells Integrity Expert System, which allows us to rapidly deploy enhancements, upgrades, changes to codes and standards in an efficient manner.

  • NEXUS IC accommodates bespoke modifications to suit your own business needs (for example, bespoke dashboards, reporting, notifications) while leveraging all the benefits associated with the expert system subscription.

  • NEXUS IC is designed to accommodate considerable end-user modifications, which avoids the need for personalised modifications having to be an expensive programmer involved process. Expert users in your own organisation or our extensive team of operational support and deployment technicians can perform rapid modifications to the system (for example, adding a new report function).

  • NEXUS IC has a number of expert systems covering a wide range of applications and as such has a large global development support team and our ability to quickly provide operational support which will greatly enhance your current support network.

Additional Features

NEXUS provides all iWIT functionality with the following additional features:

  • Digital workpack management and enactment through IC Inspector (see IC-Inspector)

  • Inspection management interface to store multimedia, trend data and identify anomalies

  • Library functionality to capture drawings and documentation referenced by components

  • Anomaly management interface to ensure well failures are appropriately risk assessed and remediated

  • Customisation reporting engine to enable creation of bespoke reports independently

  • Enhanced, configurable dashboarding system (including ISO compliant WBS dashboard) to create your own bespoke interfaces

Migration - On-Premises Deployment

  1. You contact Wood to request migration.
