Abstract
Modular debris chambers of a debris extraction tool and a method for collecting debris using such modular debris chambers are disclosed. The modular debris chamber for a debris extraction tool may include a plurality of debris chambers. The modular debris chamber may include a bucket for collecting debris, an inner flow tube being concentrically arranged within the bucket, and a deflector arranged in a lower end of the bucket for deflecting a flow of debris from the inner flow tube of a subsequent modular debris chamber connectable to a lower end of the modular debris chamber. The method for collecting debris using a modular debris chamber may include a plurality of the modular debris chambers interconnected to form a debris extraction tool, and reflecting fluid off the deflector allowing solid debris in the flow of debris to deflect off the deflector into the bucket of a subsequent modular debris chamber.
