Abstract
Junk basketis provided for collecting debris from a wellbore cleaning operation, and includes a central mandrelhaving a throughboreand an outer shelldefining a generally annular junk space. The outer shellmay be configured such that the annulusincludes a reduced portion. Flow holesin the outer shell are preferably angled substantially upward, and are positioned to discharge fluid to the annulus. According to a method of the invention, fluid is passed from an upper tubing string, through the central mandrel, into the wellbore and upward through the annulus and past the flow holes, thereby reducing pressure of flow past the well holes to pass fluid from the junk space through the flow holes.
