Diedrich Drill Inc.
March 1, 2005
Diedrich Drill's sonic rig features an automatic rod-maneuvering system that delivers drill rod and up to 13-inch diameter casing to the drill head, a 10-foot jib crane for support truck assistance and a fixed breakout table and floating makeup table for positive tool joint pre-torquing. Force is generated by rotating eccentric weights, and the mechanical spring isolation system is designed for the full retract force. At 180 Hz, Diedrich's sonic head produces 78,906 pounds of force. The sonic head is built from CAD drawings, and replacement parts are in stock. Diedrich Drill Inc., Card No. 316
