Mud filtrate property measurement for downhole contamination assessment
A method and system for measuring drilling fluid filtrate. The method may comprise disposing a downhole fluid sampling tool into a wellbore at a first location, activating a pump to draw a solids-containing fluid disposed in the wellbore into the downhole fluid sampling tool, drawing the drilling fluid with the pump across the at least one filter to form a drilling fluid filtrate, drawing the drilling fluid filtrate with the pump through the channel to the at least one sensor section, and measuring the drilling fluid filtrate with the at least one sensor. A system may comprise a downhole fluid sampling tool. The downhole fluid sampling tool may comprise at least one multi-chamber section, at least one sensor section, at least one filter, a pump, and a channel.
1. A method for measuring drilling fluid filtrate, comprising:
disposing a downhole fluid sampling tool into a wellbore at a first location, wherein the downhole fluid sampling tool comprises:
at least one multi-chamber section;
at least one sensor section, wherein at least one sensor is disposed in the at least one sensor section;
at least one filter, wherein the at least one filter is disposed in the at least one multi-chamber section; and
a channel, wherein the channel fluidly connects the at least one multi-chamber section to the at least one sensor section; and
activating a pump to draw a solids-containing fluid disposed in the wellbore into the downhole fluid sampling tool;
drawing a drilling fluid with the pump across the at least one filter to form a drilling fluid filtrate;
drawing the drilling fluid filtrate with the pump through the channel to the at least one sensor section; and
measuring the drilling fluid filtrate with the at least one sensor.
2. The method of claim 1 , wherein the at least one multi-chamber section comprises a plurality of chambers and wherein the filter is disposed in at least one of the plurality of chambers.
3. The method of claim 1 , wherein the filter is disposed in a cartridge, and wherein the filter comprises at least one mesh configured to remove large particulates or fine particulates.
4. The method of claim 3 , wherein the cartridge further comprises an attachment device configured to attach the cartridge to the at least one multi-chamber section.
5. The method of claim 1 , wherein the filter further comprises a vortex centrifuge configured to reduce particulates from the drilling fluid before filtering the drilling fluid through the filter.
6. The method of claim 1 , wherein the multi-chamber section comprises a bypass around the filter.
7. The method of claim 1 , wherein the filter further comprises a plurality of flocculants.
8. The method of claim 1 , wherein the multi-chamber section further comprises a plurality of flocculants disposed in a container that is fluidly coupled to the filter through a valve.
9. The method of claim 1 , further comprising moving the downhole fluid sampling tool to a second location and repeating the steps of activating the pump, drawing the drilling fluid, drawing the drilling fluid filtrate, and measuring the drilling fluid filtrate.
10. The method of claim 1 , further comprising calibrating the at least one sensor at least partially with the measurements of the drilling fluid filtrate.
11. A system for taking a clean fluid composition, comprising:
a downhole fluid sampling tool comprising:
at least one multi-chamber section;
at least one sensor section, wherein at least one sensor is disposed in the at least one sensor section;
at least one filter, wherein the at least one filter is disposed in the at least one multi-chamber section; and
a pump configured to draw a drilling fluid across the at least one filter to form a drilling fluid filtrate and draw the drilling fluid filtrate through a channel to the at least one sensor wherein:
the channel fluidly connects the at least one multi-chamber section to the at least one sensor section; and
the at least one sensor is configured to measure the drilling fluid filtrate.
12. The system of claim 11 , wherein the at least one multi-chamber section comprises at plurality of chambers and wherein the filter is disposed in at least one of the plurality of chambers.
13. The system of claim 11 , wherein the filter is disposed in a cartridge and wherein the filter comprises at least one mesh configured to remove large particulates or fine particulates.
14. The system of claim 13 , wherein the cartridge is disposed in the at least one multi-chamber section.
15. The system of claim 14 , wherein the cartridge further comprises an attachment device configured to attach the cartridge to the at least one multi-chamber section.
16. The system of claim 11 , wherein the at least one filter comprises a vortex centrifuge configured to reduce particulates from a solids-containing fluid before filtering the solids-containing fluid through the filter.
17. The system of claim 11 , wherein the multi-chamber section comprises a bypass around the filter.
18. The system of claim 11 , wherein the at least one filter further comprises a plurality of flocculants disposed in the filter.
19. The system of claim 11 , further comprising a container, wherein the container is disposed in the multi-chamber section and a plurality of flocculants disposed in the container.
20. The system of claim 11 , wherein the at least one sensor is calibrated at least partially with the measurements of the drilling fluid filtrate.
