Software

Expro has maintained an ongoing focus on developing software in alignment with industry standards. Developed for over ten years, the core SafeWells® product has always provided strong functionality to align with the following chapter headings from ISO 16530-1:

• Well integrity and policy strategy
• Resources, roles and responsibilities
• Risk assessment procedures
• Well component performance standards
• Well operating limits
• Well monitoring and surveillance
• Well handover
• Well maintenance
• Well integrity failure management
• Management of change

Expro also provides a range of newly developed system modules.

The source module has been developed to allow integration with the many data sources, including spreadsheets, utilizing one simple framework.

In addition to this, the MAASP (maximum allowable annulus surface pressure) calculator has been developed to provide an auditable process for accurately determining MAASP, in line with 'annulus management' requirements of ISO 16530-1. Our calculator is based on the formulae provided in the ISO standard, and also on the lookup tables in API 53C. It provides a consistent, repeatable, and auditable process for accurately determining MAASP.

Ensuring operators are compliant with 'well barrier' ISO compliance requirements is achieved through the Barriers module, which has been introduced to visualise the primary/secondary envelopes. The concept of 'leak paths' is also being introduced and aligns with the standard.

A range of SafeWells software reports have also been developed to deliver the reporting requirements specified in ISO 16530-1:

• Well barriers
• Well integrity and reporting
• Compliance audit
• Well maintenance
• Risk management
• Failure management
• Management of change
• Well handover
• Well component performance standards
• Operating limits
• Annular pressure management
• Monitoring and surveillance
