Abstract

A downhole fluid sampling tool may include: 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 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 configured to prevent 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 wax.

7 . The downhole fluid sampling tool of claim 6 , wherein the wax comprises a paraffin wax, and wherein the paraffin wax is brushed onto the filter or poured into a mold and connected to the filter.

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

9 . The downhole fluid sampling tool of claim 1 , wherein the removable filter cover is connected to an actuator, wherein the actuator is configured to move the removable filter cover to allow fluid to contact the filter.

10 . The downhole fluid sampling tool of claim 9 , wherein the removable filter cover comprises thermoplastic and/or steel.

11 . 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 configured to prevent fluid contact with the filter;
removing the removable filter cover from the filter; and filtering at least a portion of the engineered fluid pill using the filter.

12 . The method of claim 11 , further comprising positioning a pill of engineered fluid into the wellbore, wherein the engineered fluid comprises a base fluid and particulates and positioning the downhole fluid sampling tool into the pill of engineered fluid.

13 . The method of claim 11 , wherein the removable filter cover comprises a wax and wherein removing the removable filter cover comprises allowing the wax to melt in the wellbore.

14 . The method of claim 11 , wherein the removable filter cover comprises a hydrolysable material and wherein removing the removable filter cover comprises allowing the hydrolysable material to hydrolyze with water present in the wellbore.

15 . The method of claim 11 , wherein the removable filter cover is connected to an actuator, and wherein removing the removable filter cover comprises actuating the actuator to move the removable filter cover.

16 . The method of claim 15 wherein the one or more removable filter covers comprise thermoplastic and/or steel.

17 . The method of claim 11 , wherein the flow port comprises one or more probes.

18 . The method of claim 17 , 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.

19 . The method of claim 11 , 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.

20 . The method of claim 11 , 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.
