A Brief History of Stacey Oil Services
Stacey was founded in 1975 on two basic principles optimum safety and impeccable quality. Throughout the world we have been involved in numerous projects where Rotating Control Diverter Head™ technology has been required, including underground blowouts, relief wells, underbalance/near balance wells, geothermal, foam cementing, coalbed methane, oil and gas wells etc. These projects have been invaluable to our extensive data collection policy, which enables us to constantly monitor, assess and improve our equipment.

Integrated Approach
We work closely with Operators, Drilling Contractors, Well Service companies, Reservoir companies, Consultants, Government bodies and Research facilities when planning projects. Customer requirements and input are paramount, along with Well control, Safety, Training, HSE issues, and IADC recommended UBO level Designations. This integrated approach allows us to tailor equipment packages to suit specific Customer requirements.

What is a Rotating Control Divertor Head?
The RCDH™ diverts hazardous gas, steam and cuttings away from the rig and personnel, and is recognised by API as a Divertor. The RCDH™ is not a Blowout Preventer. This allows the rig crew to drill under pressure while rotating, and strip in and out of the hole. The Divertor is a key piece of Underbalanced Equipment, of which there are three types, Active, Passive and Hybrid. The Stacey RCDH™ is passive.
