Type LL Releasing Circulation Junk Basket
Product Overview
Reverse Circulating Junk Basket (RCB) is a junk retrieval tool designed to remove all types of objects from the bottom of the well bore. This superior tool removes such items as slips, hand tools, bit cones, and any other small pieces of junk from the well. The RCB uses reverse circulation to aid junk recovery.
Make up the junk basket to the bottom of the string and run into the hole. When the tool is approximately 10 feet from the bottom of the hole, the ball is dropped down the drill pipe. The ball will position itself in the ball seat and reverse circulation will begin. Circulate and begin coring. Combined with the reverse circulation, this guarantees that any junk on the bottom is pumped into the barrel and caught by the catcher assembly. The tool is removed from the hole after cutting 10 to 20 inches of core.
