Abstract

An inflow promotion arrangement including a housing; and a promotion configuration within the housing, the promotion configuration actuatable by fluid from a relatively higher productivity index zone of a wellbore.

First claim

What is claimed is:

1. An inflow promotion arrangement comprising: a housing defining a main flow pathway; and a promotion configuration within the housing, outside of the main flow pathway and between the main flow pathway and a formation in which the inflow promotion arrangement is disposed during use, the promotion configuration actuatable by fluid from a relatively higher productivity index zone of a wellbore the promotion configuration operable to enhance production flow rate from a relatively lower productivity index zone to nearer a potential level of production flow rate achievable from the higher productivity index zone.

2. The arrangement as claimed in claim 1 further comprising a power fluid inlet.

3. The arrangement as claimed in claim 1 further comprising a draw inlet.

4. The arrangement as claimed in claim 1 further comprising a joint outlet.

5. The arrangement as claimed in claim 2 wherein the power fluid is a fluid from the relatively higher productivity index zone.

6. The arrangement as claimed in claim 2 wherein the power fluid inlet is connected to the promotion configuration.

7. The arrangement as claimed in claim 1 wherein the promotion configuration is a venturi tube.

8. The arrangement as claimed in claim 1 wherein the promotion configuration is a turbine system.

9. The arrangement as claimed in claim 8 wherein the turbine system includes a drive turbine and a driven turbine.

10. The arrangement as claimed in claim 9 wherein the driven turbine is an impeller.

11. A wellbore system comprising: a relatively higher productivity index zone of the wellbore; a relatively lower productivity index zone of the wellbore; and an inflow promotion arrangement outside of a main flow pathway and between the main flow pathway and a formation in which the inflow promotion arrangement is disposed during use, the inflow promotion arrangement operably connected to the relatively higher productivity index zone and promotionally connected to the relatively lower productivity index zone, the promotion arrangement enhancing production flow rate from a relatively lower productivity index zone to nearer a potential level of production flow rate achievable from the higher productivity index zone.

12. The wellbore system as claimed in claim 11 further comprising a filter.

13. The wellbore system as claimed in claim 12 wherein the filter comprises a screen.

14. A housing; and a promotion configuration within the housing, the promotion configuration outside of a main flow pathway and between the main flow pathway and a formation in which the promotion configuration is disposed during use, the promotion configuration actuatable by fluid from a relatively higher productivity index zone of a wellbore to promote production flow from a lower productivity index zone of the wellbore.

15. The wellbore system as claimed in claim 14 wherein the inflow promotion arrangement includes a power fluid inlet fluidly connected to the relatively higher productivity index zone.

16. The arrangement as claimed in claim 14 wherein the promotion configuration is a venturi tube.

17. The arrangement as claimed in claim 14 wherein the promotion configuration is a turbine system.

18. A method for producing a wellbore comprising: flowing a power fluid from a relatively higher productivity index zone of the wellbore fluid through an inflow promotion arrangement outside of a main flow pathway and between the main flow pathway and a formation in which the inflow promotion arrangement is disposed during use, to power the inflow promotion arrangement; and promoting flow of fluid from a relatively lower productivity index zone of the wellbore with the inflow promotion arrangement thereby enhancing production flow rate from a relatively lower productivity index zone to nearer a potential level of production flow rate achievable from the higher productivity index zone.

19. The method as claimed in claim 18 wherein the power fluid flows through a venturi tube creating a low pressure at a draw inlet and drawing fluid into the inflow promotion arrangement.

20. The method as claimed in claim 18 wherein the power fluid flows through a turbine system creating a low pressure at a draw inlet and drawing fluid into the inflow promotion arrangement.
