Preventative Maintenance and In-situ Repair

Many of the fields operated by our clients are made up of mature wells and utilise a variety of manufacturers’ equipment. At Well-Centric, we work on all Original Equipment Manufacturers (OEM) equipment. We have extensive experience of the following types of surface wellhead equipment:

  • Vetco Gray (GE)
  • Cameron
  • Wood Group (GE)
  • Dril-Quip
  • FMC

Our onsite maintenance services include, but are not limited to:

  • Annual and bi-annual planned inspections and maintenance of xmas trees and wellheads
  • Ad-hoc, unplanned inspections and maintenance of xmas trees and wellheads
  • Annulus and xmas tree pressure monitoring and testing
  • Lubrication of xmas tree, wellhead valves and associated fixtures and fittings
  • Valve & actuator in-situ repairs
  • Valve & actuator replacement
  • Repair wellhead void leaks by injecting & testing third party compounds - Alchemy sealing materials

For parts that cannot be repaired onsite, we can mobilise them to our workshop for full repair or refurbishment. This ensures surface trees and wellheads can be put back into service efficiently to keep Capex spend down.
