End-to-end well delivery

Well Construction

Well intervention

Fishing

We maintain one of the largest inventories of fishing tools in Nigeria and have more than 100 combined years of experience in fishing operations in-country. Our fishing specialists have successfully worked across many oilfields in Nigeria.

During drilling, workover, or production activities, tools, junk, debris, or other foreign objects may become stuck in the well and disrupt operations. Our trained personnel use specialized fishing tools and proven recovery techniques to retrieve these objects, restore well access, and optimize the continued use of the well.

Well decommissioning

Plug, Abandonment & Slot Recovery

The plug-and-abandonment process involves installing permanent barriers to safely seal an oil well or a section of the well. Where casing retrieval is required for slot recovery or permanent abandonment, a dependable and experienced service partner is essential.

With our broad tool inventory and operational expertise, we can recover casing while reducing intervention time across different installation types. For offshore and deepwater installations, we provide single-trip cutting and recovery solutions that help reduce lengthy intervention periods and associated project costs.

Rental services

Drillpipe Tubular Rentals

Tubulars used in oil and gas production include drill pipes, pup joints, casing, and tubing. Because these assets are exposed to rust, wear, and demanding operating conditions, their maintenance, storage, and logistics can present significant operational challenges.

We provide dependable tubular rental services and a broad range of tubing, drill-string, handling, and ancillary tools. This allows clients to access properly maintained equipment while reducing storage, ownership, and maintenance costs.

Downhole performance

Jar & Downhole Tools

Downhole tools are used throughout oilfield drilling, completion, intervention, and workover activities. We provide a wide range of in-country drilling and downhole tools, supported by automated machine operations that improve efficiency and help reduce project time and cost.

Our equipment is professionally managed and supported by efficient on-site services. We have the capacity to provide specialized tools that improve operational performance and minimize drilling and production costs, including drilling jars, fishing tools, drill pipes, tubular tools, wireline tools, and slickline equipment.
