The Haymaker is a coiled tubing vibratory/extended reach tool that uses a negative pressure pulse to create an axial force at a low frequency, resulting in a periodic fluid hammer effect which stimulates the coiled tubing to reduce frictional drag.
Applications
- Extended reach well stimulation operations
- Extended reach well intervention procedures
- Extended reach composite bridge plug milling
- Extended reach fracture hardware milling
- Extended reach toe preparation
- Extended reach sand clean-out
- Extended reach production logging
- Extended reach abrasive perforating
Overview
To achieve maximum tool efficiency, approximately 5%-8% of the fluid being pumped down the coil tubing is vented to the annulus through a nozzle near the bottom of the Haymaker. This venting generates a more efficient negative pressure pulse, which produces the fluid hammer effect responsible for breaking friction. The low frequency negative pressure pulse actuates the coiled tubing over a longer period, allowing the coiled tubing more time to move. The fluid venting also permits slightly higher pump rates, which in turn improves debris removal and well cleaning.
