Grease Injection Control Heads - American Completion Tools

	Grease Injection Control Heads

Grease Injection Control Head (GICH) is required to obtain a seal when using braided line for heavy duty such as swabbing or fishing.

Principle of Operation: Grease is injected at a pressure higher than the well pressure (approximately 20% higher). The grease fills the interstitial grooves between the braided line stands. The most critical component of the grease injection head are the 'flow tubes'. These should be approximately 0.010" ID larger than the measure ODS of the o-line. The seal is achieved by the pressure drop created across the small gap between the line and flow tubes.
A wiper box on top of the grease injection head retains a large percentage of the grease.

Ancillary Equipment:
The following equipment are required to operate the grease injection system

Compressor (Back-up system essential in high pressure situations)
Grease reservoir
Grease Pump
Connection hoses
Dual BOP system

Use:
The following factors will effect the volume of grease required:

Clearance between the flow tubes and line
Temperature
Well pressure
Line Speed
Line Size
Grease viscosity
