Abstract

A debris management assembly including a housing, a mandrel disposed within the housing, a debris sump defined between the mandrel and the housing, and a debris diverter operably connected to the mandrel and positioned to direct debris that encounters the debris diverter into the debris sump.

First claim

What is claimed is:

1. A debris management assembly comprising:
a housing;
a mandrel disposed within the housing;
a debris sump defined between the mandrel and the housing; and
a debris diverter operably connected to the mandrel and positioned to direct debris that encounters the debris diverter into the debris sump, wherein the debris diverter includes a flap pivotally connected to the mandrel at a pivot and further comprises a counter tab extending in a direction from the pivot opposite a direction of extension of the flap.

2. The assembly as claimed in claim 1 wherein the debris sump is part annular.

3. The assembly as claimed in claim 1 wherein the debris sump is fully annular.

4. The assembly as claimed in claim 1 wherein the debris diverter is conically shaped.

5. The assembly as claimed in claim 1 wherein the debris diverter is triangular-pyramidally shaped.

6. The assembly as claimed in claim 1 wherein the debris diverter is square-pyramidally shaped.

7. The assembly as claimed in claim 1 wherein the flap is domed.

8. The assembly as claimed in claim 1 wherein the flap comprises a number of flaps.

9. The assembly as claimed in claim 8 wherein the flaps when brought together create the debris diverter.

10. The assembly as claimed in claim 8 wherein each of the flaps include a counter tab.

11. The assembly as claimed in claim 1 wherein the counter tab is configured to interact with an actuator.

12. A borehole system comprising:
a tubular string;
an actuator disposed in the tubular string;
an assembly as claimed in claim 1 , disposed in the tubular string the assembly being in operable communication with the actuator; and
an isolation valve disposed in the tubular string.

13. The borehole system as claimed in claim 12 wherein the actuator is a sleeve.

14. The borehole system as claimed in claim 13 wherein the sleeve is interactive with the counter tab of the debris diverter to open the debris diverter.
