System and method for determining at least one property of a porous medium

A method of determining at least one property of a porous medium, the method comprising:

• performing a first measurement on a sample of the porous medium to obtain an optical path through pores of the porous medium using a first optical sensor configured to utilize a first optical technology;
• performing a second measurement on the sample of the porous medium to obtain a total optical path through the porous medium using a second optical sensor configured to utilize a second optical technology different from the first optical technology;
• and
• calculating an optical porosity of the porous medium, based on the optical path through the pores, and the total optical path through the porous medium,
• wherein the first and second measurements are performed in an in-line implementation.

A method of determining at least one property of a porous medium, the method comprising:

• performing a first measurement on a sample of the porous medium to obtain an optical path through pores of the porous medium using a first optical sensor configured to utilize a first optical technology;
• automatically moving the sample between the first optical sensor and a second optical sensor configured to utilize a second optical technology different from the first optical technology, wherein an illumination and detection of the sample for the first and second measurements are performed in the same optical geometry;
• performing a second measurement on the sample of the porous medium to obtain a total optical path through the porous medium using the second optical sensor, wherein the first measurement and the second measurement are performed sequentially on the sample;
• and
• calculating an optical porosity of the porous medium, based on the optical path through the pores, and the total optical path through the porous medium.
