Abstract
Techniques for determining at least one rock property of a core sample include measuring a first nuclear magnetic resonance (NMR) spectrum signal of a test fluid enclosed at a particular pressure in a cylinder of an NMR pressure cell; measuring a second NMR spectrum signal of a core sample immersed in the test fluid; removing a background NMR spectrum signal from the first and second NMR spectrum signals to determine a bulk test fluid NMR spectrum signal and a combined test fluid and core sample NMR spectrum signal; determining a porosity of the core sample based on the bulk test fluid NMR spectrum signal, the combined test fluid and core sample NMR spectrum signal, a dimension of the core sample, and a dimension of the cylinder; and determining a fluid intake capacity of the core sample based on the porosity and the dimension of the core sample.
