Expro Excellence
Subsea Well Access
Expro completes 15 well abandonment campaign with zero NPT
Customer challenges
  • Expro’s client had the requirement for a subsea well access system to provide well barriers during a subsea well abandonment campaign in West Africa
  • This abandonment campaign was to be carried out by a drill ship with a dual activity drill floor
  • Expro supported our client with the provision of an Open Water Intervention Riser System (OWIRS) and controls package (SPS Xmas Tree and OWIRS controls)
  • Expro provided project management, interface engineering and service personnel to deliver the full scope, which included a compact OWIRS, surface flowhead, umbilical’s, topsides control equipment and IWOCs package under the one integrated contract
  • Our customer required a rental OWIRS as their subsea well access method to interface with the Xmas Tree because:
  • Xmas Tree type and upper interface could not accommodate a drilling BOP
  • The original workover system was no longer available
  • Coil tubing intervention as a contingency was ruled out of RWIS
Expro Excellence
  • OWIRS system was successfully bunny hopped for six wells in the schedule: system subsea for just over three weeks
  • Personnel skill sets were transferred from Expro’s SSTTA product line
  • Zero leak gas testing was carried out on the main barriers post operation, proving the system reliability after more than 250 functions and 16 months in the field
  • Performance recognised by client in Australia who will now take equipment on rental to perform very similar work scope
