Wellhead Maintenance & Integrity Management Services

Fairtex Nigeria Ltd delivers comprehensive wellhead maintenance and integrity management services supporting oil & gas production operations across onshore and offshore environments. Our capabilities cover surface wellheads, Xmas trees, valves, actuators, and associated pressure control systems for both new HP/HT developments and mature brownfield assets.

We provide routine inspection, preventive maintenance, corrective repair, pressure testing, and integrity verification services designed to ensure well barrier reliability, production continuity, and operational safety. Fairtex deploys dedicated field units and portable workshop containers equipped for on-site intervention, testing, and equipment refurbishment.

Typical applications: producing wells, HP/HT developments, brownfield rehabilitation, offshore platforms, onshore flow stations, production manifolds, injection wells, and aging well stock requiring integrity restoration and verification.

What this service covers

Well Integrity Testing & Barrier Verification

Fairtex performs well integrity testing including Xmas tree valve testing, subsurface safety valve (SCSSSV) checks, annulus valve verification, hanger seal and pack-off testing, and full well barrier validation. These services ensure containment integrity and compliance with production safety requirements.

Valve Maintenance & Pressure Control Services

We provide maintenance and repair of gate valves, annulus valves, production chokes, and actuators including greasing, sealing, pressure testing, and in-situ refurbishment. Pressure control lubricator services and Seal-Tite engineered sealing solutions are applied to restore operational reliability and prevent leakage or failure.

In-Situ Repairs & Xmas Tree Servicing

Fairtex carries out in-situ Xmas tree valve repairs, actuator servicing, valve change-outs, greasing, inflow testing, and full functional testing of surface wellhead systems. Where required, complete Xmas tree removal, refurbishment, upgrade, and reinstallation are executed to restore full operational capability.

Annulus Management & Well Surveillance

Our services include annulus fluid management, annulus integrity monitoring, corrosion surveys, echo meter surveys, and liquid level detection analysis. These activities support early detection of integrity issues and long-term well health management.

Field Mobile Workshop & Specialized Equipment Support

Fairtex deploys mobile workshop units designed for field maintenance operations, equipped with high-pressure test pumps, grease injection systems, pressure washers, and specialized sealing tools. These units enable on-site intervention, rapid repairs, and high-pressure testing up to operational requirements.
