What Role Can NMR Play In Core Analysis?

Nuclear magnetic resonance (NMR) is known for being one of the top analytical methods in modern chemistry. But NMR can also complement other analytical methods in various industries including the petroleum industry.

In petrophysics, accurate rock core analysis is crucial to conducting flow experiments on core plugs taken from a petroleum reservoir. NMR can not only play a major role in core analysis but it can also complement other popular analytical techniques.

How can NMR complement existing core analysis techniques?

A core is a sample of rock that's taken from the side of a drilled oil or gas well. The core is dissected into core plugs, dried, and measured using techniques such as resistivity and mercury porosimetry.

NMR isn't an alternative to resistivity measurements and mercury porosimetry. It complements these methods because it applies more measurements to an imprecise science to gather better results.

Mercury porosimetry provides information about pore distribution and the shapes of the pores. Resistivity is able to help with fluid type. NMR can help to provide more information about fluid type and pores alike.

NMR is capable of focusing on fluid behavior inside the given rock in a way that other techniques can't. It determines how much fluid will flow through the rock and provides greater visibility of the total fluid volume. This means you'll know how much oil will flow and how much oil will be bound by capillary pressure when you break a well.

Why should NMR be an essential part of my toolkit?

Nuclear magnetic resonance provides more data for rock core analysis than you can achieve with porosimetry and resistivity alone such as fluid typing, capillary pressure, and fluid distribution. NMR also has the potential to determine permeability, capillary pressure, and gas/water or oil/water contents.

NMR is an essential part of your rock core analysis toolkit because it gives you a greater ability to prove into the volume and behavior of fluids for a better analysis.

Looking for a benchtop spectrometer for your lab?

NMR spectrometers are not only great for studying nuclei such as hydrogen nuclei, which is the number one most-studied nuclei. Benchtop spectrometers also enable scientists in different industries to analyze data from fluid typing, capillary pressure, and fluid distribution.
