Hunting grease injection control heads are designed to contain well pressure whilst running braided line or electric line cable operations.

Grease injection control heads are made up of two main assemblies, the pack off/line wiper assembly and the flow tube assembly.

The pack off assembly provides sealing capabilities when the wireline is stationary. Dual pack offs are available when higher well pressures are anticipated.

The line wiper is energised to clean the cable when pulling out of the well. The Hunting cleanline system incorporates an integral line wiper within the pack off assembly eliminating the requirement for a separate drain hose for the line wiper.

The flow tube assembly is made up of a number of close tolerance flow tubes that are sized to the diameter of the wireline/cable being used. Grease is then pumped into the annular void between the flow tube and the cable creating a pressure drop across each flowtube.

The number of flow tubes required is dependent on expected well pressures and well fluids.

An additional flowtube injection assembly can be added to provide more grease volume.
