A review of the nuclear magnetic resonance physics and application in petroleum industry

摘要: The measurement of the nuclei response to an external magnetic field known as nuclear resonance (NMR) has proven have wide application covering different industries. NMR use in petroleum industry focuses on solving rock and fluid properties. T2 is dominant due short time comparison with T1, at same time, it generates required information. nondestructive technique echo decay sequence commonly utilized characterize pore structure by observing static dynamic aspects spin. measured controlled geometry (pore size), therefore, mean can potentially be used estimate permeability. spectra, however, affected presence paramagnetic minerals either reservoir or drilling fluid. Its shallow depth investigation makes prone formation damage during drilling; provides vast data improve understanding This article reviews basic physics, added value through its reservoir, productivity, such porosity, size distribution, permeability, capillary pressure.
