Abstract
An apparatus and method for retrieving debris from the well bore of an oil or gas well. The apparatus comprises a junk basket with a flow passage that allows fluid to be jetted out end of the tool while the tubing string is advanced to stir up the debris in the well fluids and facilitate capture of the debris in the strainer basket. Importantly, upon encountering a plug of sand or other debris in the well bore, fluid flow through the tool can be increased to work on the plug until it breaks apart. Advancement of the tubing string can be halted and resumed, as needed, in combination with control of the fluid flow through the tool until the junk basket is full or the targeted debris is collected, whereupon the junk basket is withdrawn. The junk basket may be deployed on coiled tubing or a string of drill pipe.
