Buckman Jet Drill
BJD’s internationally patented nozzle, typically known as Buckman’s Nozzle is the heart of the jet drilling system. With four models of nozzles developed over the last decade, Buckman’s Nozzles can efficiently and economically penetrate multiple formation types.
The nozzle’s front orifice creates a full cone vortex of high pressure fluid cutting the full diameter of the jet bit without using abrasives, while the rear jets propel the nozzle forward. The rear jets cut into the rock with the signature BJD star pattern increasing the contact area six-fold.
Technical Information
Jet bit penetration through Berra sandstone with compressive strength of 3500 psi, porosity of 16% and permeability of 69 mDarcies. Pressure at the Jet bit was 9,000 psi
