Abstract

Turbidity measurement systems and methods of using the same are described. A turbidity measurement system comprises a vessel configured to hold a wellbore fluid, wherein a porous media is positioned in the vessel; a light source positioned to direct light at the vessel; a light detector positioned to measure light intensity of light emitted by the light source and passing through the vessel; a backscatter detector configured to measure the light intensity of reflected light emitted from the light source; and a computer system communicatively coupled to at least one of the light source, light detector, or light detector.

First claim

What is claimed:

1 . A turbidity measurement system comprising:
a vessel configured to hold a wellbore fluid, wherein a porous media is positioned in the vessel; a light source positioned to direct light at the vessel; a light detector positioned to measure light intensity of light emitted by the light source and passing through the vessel; a backscatter detector configured to measure the light intensity of reflected light emitted from the light source; and a computer system communicatively coupled to at least one of the light source, light detector, or light detector.

2 . A system according to claim 1 , wherein the light source, light detector, and backscatter detector are capable of scanning the entirety of the length and/or width of the vessel.

3 . A system according to any of claim 1 , wherein the light source, light detector, and backscatter detector are not connected together as a single unit.

4 .- 10 . (canceled)

11 . A method for measuring the turbidity of a wellbore fluid comprising:
injecting a volume of wellbore fluid into the interior of a vessel, wherein a porous media is positioned in the vessel; passing the wellbore fluid through the porous media; measuring the turbidity of the wellbore fluid with a turbidity measurement apparatus, wherein the turbidity measurement apparatus comprises a light source, a light detector, and a backscatter detector; and using the measured turbidity data to determine thickness of a filter cake formed at an interface of the porous media and the wellbore fluid.

12 . A method according to claim 11 , wherein the light source, light detector, and backscatter detector are capable of scanning the entirety of the length and/or width of the vessel.

13 . A method according to claim 11 or 12 , wherein the light source, light detector, and backscatter detector are not connected together as a single unit.

14 . - 20 . (canceled)
