Thank so much for simple and detailed explanation😃👍
thank you so muchh!!!
Thanks for your nice explaination. Just wanted to ask: How NMR help us in Facies indentification?
Earth Science
How do we differentiate between gas, oil an water? Also, between light oil, medium oil and heavy oil?
T1 gives informations about chemical properties
@@sizenproduction9107 thats all you have as an information and response???
Gas have longer T1 values and polarization time as they have low hydrocarbon density and much higher molecular self diffusion. When you only have oils in the sample, you ll have longer T2 values than flr water as surface relaxivity is lower for oils than for water (around 1/3) in case of mixed oil and water, you will see doubled T2 peaks, one peak for the water and one for oil (even though it's sometimes hard to see it depending on the wettability of the rock). The heavier the oil is the lower T2 relaxation time it will have.
You can check a website called "petrowiki" and those articles : Petrophysical Principles of Applications of NMR Logging, W.E Kenyon / Caractérisation de structures poreuses par relaxométrie RMN, M. fleury
@@sizenproduction9107 now this a great response. Thanks!
