Retrievable TorqueMaster Bottom Set Anchor - 5.5" 14.0–26.0 lb/ft
The Baker Hughes TorqueMaster™ bottom-trip retrievable anchor is used to anchor a whipstock in the wellbore. It is an alternative to the packer/anchor assembly, and attaches to the lower end of the whipstock by means of a drillpipe thread. The bottom trip retrievable anchor is for use with the WindowMaster G2™ and the PathMaster™ window milling systems.
- No welded components - enhances durability
- Simple operation - Does not require circulation to activate
- Retrievable design - allows for slip retraction, which prevents scarring casing during the retrieval process
- Uses the proven TorqueMaster cam-cone slip system - eliminates risk of rotation

The retrievable TorqueMaster bottom set anchor is primarily used with the WindowMaster™ one-trip window milling system but it can also be run with the two-trip type E window milling system.
To activate the setting sequence, only a bottom restriction is required. This bottom can be in the form of a permanent or retrievable bridge plug, top of cement, liner top, production packer, etc.
When using the retrievable TorqueMaster bottom set anchor, either the universal bottomhole orientation (UHBO) or the measurement while drilling (MWD) orientation method can be used.
The anchor is retrievable with straight overpull on the whipstock. For retrievable applications, a debris management system consisting of an EXCLUDER™, unloader, and emergency disconnect should be run between the whipstock and the anchor. The debris management system will keep debris from falling around the anchor and possibly fouling the slips during retrieval.
