摘要

Apparatus and methods for performing downhole operations. The apparatus can include a sealing mechanism having an inner bore formed therethrough; a check valve adjacent the sealing mechanism; a circulation device adjacent the check valve; and a rotatable nozzle adjacent the circulation device. The circulation device can include a first tubular member having a radial hole formed therethrough, and a second tubular member disposed about at least a portion of the first tubular member. The second tubular member can also have a radial hole formed therethrough, and the second tubular member can be adapted to longitudinally move about the first tubular member from a first position to a second position.
