We inspect, repair, and maintain wellhead equipment to keep your wells producing safely and without interruption. Our team conducts pressure testing, integrity checks, risk assessments, and emergency interventions, all documented and reported to industry and HSE standards.
Wellhead equipment operates under extreme pressure and must perform without failure. Oaservs provides hands-on inspection, maintenance, and emergency intervention services to keep your wellheads compliant, safe, and operational with full documentation at every stage.

We work directly on site, coordinating with your operations team to minimise downtime and ensure every action taken is recorded, reported, and traceable.
Scheduled and unscheduled inspections of wellhead equipment to identify wear, corrosion, seal degradation, and structural integrity issues before they become failures
On-site repair and component replacement for wellhead assemblies, including valves, seals, flanges, and Christmas tree components.
Pressure testing of wellhead assemblies and related equipment to verify containment integrity and confirm compliance with operational pressure ratings.
Rapid response to wellhead equipment failures or anomalies requiring immediate attention. We mobilise quickly and work under your emergency protocols to restore safe operations.
Pre-job risk assessments and safety planning for all wellhead activities, with execution carried out in full compliance with HSE standards and applicable industry regulations.

At the close of every wellhead engagement, you receive a complete service package including:
HSE & Compliance: All wellhead services are carried out in accordance with applicable HSE standards and the regulatory requirements of the country of operation. Oaservs operates under Chadian jurisdiction and adheres to the regulations of every country in which it provides services.
We service a broad range of wellhead equipment including surface wellhead assemblies, Christmas trees, gate valves, choke valves, flanges, seals, and casing heads. If you have a specific component or configuration you need assessed, contact us with the details and we will confirm scope before mobilising.
For emergency well interventions, we aim to respond within 24 hours of your request. Mobilisation time depends on site location and the equipment and personnel required. We recommend contacting us by phone for emergencies. Our team will assess the situation immediately and give you a realistic mobilisation timeline on the same call.
Yes. Oaservs is registered in Chad and operates across the CEMAC region, including Gabon, Cameroon, Congo, and the Central African Republic, without requiring additional licences. For each country we operate in, we comply fully with that country’s applicable regulations. If your site is outside the CEMAC zone, contact us to discuss what is possible.
In many cases, yes. Where replacement parts are needed, Oaservs can source and supply components through our procurement service, managing manufacturer identification, technical compliance checks, and delivery to the site. If you know in advance that parts will be required, share the specifications with us before mobilisation so we can coordinate supply alongside the service visit.
Every wellhead engagement begins with a pre-job risk assessment and a clearly defined safety plan. Our teams work in accordance with HSE standards applicable to the site and country of operation. We align with your company’s site safety requirements and will request your HSE documentation and site induction procedures before arrival. All safety actions taken during the job are recorded in the post-job report.
