Downhole Tool Repair 
& Refurbishment Solutions

OD/ID Repair

We specialise in the repair and restoration of worn or damaged internal and external surfaces through cladding, precision machining, and dimensional recovery. Our capabilities also include the fabrication and cladding of new surfaces and components for new-build, replacement, and OEM applications, delivering enhanced performance, extended service life, and compliance with customer specifications.

We provide a range of advanced welding and cladding processes, including Gas Tungsten Arc Welding, Plasma Transferred Arc Welding, and Laser, enabling us to select the most suitable process for each application based on material, performance, and service requirements.

Additional surface enhancement processes, including roller burnishing and shot peening, can also be applied to improve surface integrity, increase durability, enhance fatigue resistance, and extend component and tool service life.

Port Repair / Feature Restoration

Repair and restoration of drill collar ports or features through controlled welding, precision machining, and dimensional recovery to restore critical dimensions and functionality. Additional processes, including roller burnishing and shot peening, are available to enhance surface properties and extend service life.

Hardfacing

We provide advanced hardfacing solutions for drill collars, stabilizers, and other downhole drilling tools. These precision cladding processes restore worn surfaces, improve wear resistance, and extend tool service life in demanding drilling environments.

By applying specialised wear- and corrosion-resistant alloys to high-wear areas, we restore components to their required dimensions while enhancing durability, abrasion resistance, and overall performance. The use of PTAW and Laser Cladding ensures excellent metallurgical bonding, controlled dilution, and high-quality deposits for reliable long-term service.

Whether for repair, dimensional restoration, reinforcement, or preventive wear protection, our precision-applied hardfacing solutions reduce maintenance costs, minimize downtime, and maximize the operational life of critical drilling equipment.

Laser Welding

Precision laser welding for a wide range of repair applications, including small components, thin wall sections, critical or sensitive areas, and localised spot repairs. With controlled heat input, minimal heat-affected zone, and reduced distortion, the process enables accurate repairs while preserving component integrity.

API Threading

As a licensed API connection cutting provider, we perform API connection cutting, thread recutting, and refacing services to support new and restored connections. Additional surface treatments, such as cold rolling and shot peening, are available to enhance connection strength and overall performance.

Shot Peening / Bead Blasting

Surface enhancement treatment for drilling tools and threaded connections, including ID and OD peening, using steel shot to introduce compressive residual stress and improve fatigue strength, or glass bead for surface cleaning and a uniform finish, enhancing wear resistance and extending component service life in demanding drilling applications.
