Well compatibility verification (WCV)

Independent verification for pressure control equipment.

ModuSpec provides independent third-party verification of well control equipment against applicable regulations, standards and client-specific requirements. 

In the US, well compatibility verification (WCV) is required under 30 CFR § 250 as part of an operator's Application for Permit to Drill (APD) or Application for Permit to Modify (APM), submitted on a well-by-well basis before drilling or intervention operations can begin. 

Our verification scope can include: 

  • Equipment condition and between well maintenance.
  • Testing against applicable standards and regulations.
  • Shear verification review.
  • Provision of daily reports.
  • Accumulator calculations and capacity verification.
  • BOP fluid compatibility.
  • Environmental conditions, including temperature and H2S.
  • Technical review and reporting.
  • Final documentation.

Following satisfactory review of BOP equipment condition, maintenance, testing, shear verification, fluid and environmental compatibility and accumulator volume, ModuSpec provides a signed WCV letter is support of the planned well operations.
