Abstract

A method and system for removing a filter cover. A system and method may comprise a downhole fluid sampling tool including a tool body; a flow port disposed on the tool body; a sample chamber disposed within the tool body and fluidly coupled to the flow port; a pump disposed within the tool body. In examples, the pump is configured to pump a fluid through the flow port into the sample chamber; a filter disposed on an inlet of the flow port, wherein the filter is configured to filter the fluid entering the flow port; and a removable filter cover configured to prevent fluid contact with the filter.

First claim

What is claimed is:

1. A downhole fluid sampling tool comprising:
a tool body;
a flow port disposed on the tool body;
a sample chamber disposed within the tool body and fluidly coupled to the flow port;
a pump disposed within the tool body, wherein the pump is configured to pump a fluid through the flow port into the sample chamber;
a filter disposed on an inlet of the flow port, wherein the filter is configured to filter the fluid entering the flow port; and
a removable filter cover selectively movable between a first position where the removable filter cover prevents fluid contact with the filter and a second position where the removable filter cover allows fluid contact with the filter.

2. The downhole fluid sampling tool of claim 1 , wherein the flow port comprises one or more probes.

3. The downhole fluid sampling tool of claim 2 , wherein the one or more probes comprise at least one probe selected from the group consisting of a dual probe, a single probe, a focused probe, a packer probe, a multi-section probe, and combinations thereof.

4. The downhole fluid sampling tool of claim 1 , further comprising a second flow port and a second filter disposed on the second flow port, wherein the second filter is configured to filter a fluid entering the second flow port, and wherein the second filter further comprises a second removable filter cover.

5. The downhole fluid sampling tool of claim 1 , wherein the filter comprises at least one filter selected from the group consisting of a screen filter, a frit filter, a mesh filter, a slot filter, a media filter, a printed filter, and combinations thereof.

6. The downhole fluid sampling tool of claim 1 , wherein the removable filter cover comprises a thermoplastic material.

7. The downhole fluid sampling tool of claim 6 , wherein the thermoplastic becomes plastic when heated and hardened when cooled.

8. The downhole fluid sampling tool of claim 1 , wherein the removable filter cover comprises steel.

9. The downhole fluid sampling tool of claim 8 , wherein the steel is an alloy of at least iron and carbon.

10. A method comprising:
disposing a downhole fluid sampling tool into wellbore, wherein the downhole fluid sampling tool comprises:
a tool body;
a flow port disposed on the tool body;
a sample chamber disposed within the tool body and fluidly coupled to the flow port;
a pump disposed within the tool body, wherein the pump is configured to pump a fluid through the flow port into the sample chamber;
a filter disposed on an inlet of the flow port, wherein the filter is configured to filter the fluid entering the flow port; and
a removable filter cover selectively movable between a first position where the removable filter cover prevents contact with the filter and a second position where the removable filter cover allows fluid contact with the filter.

11. The method of claim 10 , further comprising positioning the downhole fluid sampling tool at a zone of interest prior to moving the removable filter cover to the second position.

12. The method of claim 10 , wherein the removable filter cover comprises a thermoplastic material.

13. The method of claim 12 , wherein the thermoplastic becomes plastic when heated and hardened when cooled.

14. The method of claim 10 , wherein the removable filter cover comprises a steel.

15. The method of claim 14 , wherein the steel is an alloy of at least iron and carbon.

16. The method of claim 10 , wherein the flow port comprises one or more probes.

17. The method of claim 16 , wherein the one or more probes comprise at least one probe selected from the group consisting of a dual probe, a single probe, a focused probe, a packer probe, a multi-section probe, and combinations thereof.

18. The method of claim 10 , wherein the downhole fluid sampling tool further comprises a second flow port and a second filter disposed on the second flow port, wherein the second filter is configured to filter a fluid entering the second flow port, and wherein the second filter further comprises a second removable filter cover.

19. The method of claim 10 , wherein the filter comprises at least one filter selected from the group consisting of a screen filter, a frit filter, a mesh filter, a slot filter, a media filter, a printed filter, and combinations thereof.
