The Matrix Blow-Down Sub is designed to clear blockages in the slots of the interchange, rock bit adaptor, and dual tube drill rod inner tube. Installed at the top of the Reverse Circulation (RC) drill string, it seals the annulus of the dual tube rod and directs airflow through the RC inner tube to restore proper circulation.
The Blow-Down Sub consists of two precision-engineered components: an inner tube and a durable outer body.
“In our general area we began to witness the need for deeper well completions. The Matrix design fit the bill for incorporation into the construction of these wells. By adding capability to our existing equipment, in multiple instances, we have witnessed a fuel burn rate reduction of over 35% as compared to previously used strings and bottom hole assembly designs. “We plan on continuing to configure our equipment with Matrix drill pipe. Thank you for making a great product.”
