TTRD Crown Profile Protection Sleeve
Our Technology...
What is it ?
The CPP (Crown Plug Profile) Protection Sleeve was designed for use with through tubing rotary drilling techniques and is used to protect the crown plug profile area of the christmas tree. It is normally conveyed in a piggy back mode on the TTRD Running Tool together with the safety valve TTRD Protection Sleeve.
The Running Tool is designed to function as a part of the drillstring. It carries both the CPP and TTRD Protection Sleeves into the well and picks them back up again upon retrieval from the well.
When would I use it ?
The device was developed specifically for use on TTRD operations but can be used in a number of other applications where the protection of seal bores is required:
- Through Tubing Rotary Drilling operations
- Electric and slickline operations
- Snubbing and coiled tubing operations
