Who we are

A specialist supplier of downhole intervention technology

Downhole Division is a dedicated supplier of high-performance downhole intervention tools for the global oil & gas industry. We do not manufacture equipment — instead we partner with the best manufacturers in the field to supply reliable, robust and field-proven technology for well isolation, well abandonment, surveillance and wireline operations.

Because we are independent, we recommend the right tool for your well rather than a single catalogue. Our engineering team works with your objectives, well environment and operational constraints to deliver a solution that performs.

  • We supply — customized tools & equipment — giving you unbiased access to the best tool for the job
  • Partnerships with multiple leading downhole tool manufacturers worldwide
  • Quality-assured, field-proven equipment for the most demanding well environments
  • Independent engineering support to specify, combine and deploy the right technology

Our approach

Tailored solutions, engineered around your project

Because we are an independent supplier, we combine the strengths of many manufacturers. Where a project calls for it, we integrate different manufacturers' products into one engineered solution that matches the well environment and operational requirements.

01

Best-in-class sourcing

We work with multiple leading manufacturers of downhole intervention tools, so every recommendation is driven by fit and performance — never by a single product line.

02

Tailored engineering

Our engineering team designs solutions around your well environment, objectives and constraints — often combining products from different manufacturers into a single, coherent tool string.

03

Supply & support

From specification and supply through to deployment guidance, we support your project end to end so the right equipment arrives ready to perform.
