Pack-Off Bushing

These completion accessories facilitate completion

and gravel-packing operations by providing pressure

and fluid sealing at selected points in the completion

assembly.

During sand control operation, these accessories normally

direct fluid flow in order to assist with effective fluid or

gravel movement. They can be placed at the bottom of the

screen assembly, just above a short telltale-circulating screen.

This helps insure treatment fluids are pumped all the way to

the end or bottom of the production screens to promote

complete screen coverage screen.
