Abstract:

A quantitative method of determination of rock properties from cuttings using nuclear magnetic resonance technology is given. On the basis of laborater y  experiment, differences between cuttings analysis and core analysis are studied and the feasibility of on site nuclear magnetic resonance cuttings analysis  is investigated. The method to determine the rock properties such as porosity, permeability etc. from cuttings using nuclear magnetic resonance technology is also given.

Key words: NMR, cuttings, porosity, permeability, petroleum physics
