Title (EN) METHODS AND SYSTEMS FOR DETERMINING BULK DENSITY, POROSITY, AND PORE SIZE DISTRIBUTION OF SUBSURFACE FORMATIONS

Abstract:
(EN) Herein a method and a system for determining matrix or grain density of a subsurface formation are described. This includes measuring in-air mass of a fluid-saturated sample of the subsurface formation, wherein the in-air mass comprises mass of the sample, mass of a fluid surrounding the sample, and mass of the fluid inside the sample. The volume of the fluid inside the sample, Vø, and volume of the fluid surrounding the sample, Vsur, are determined using nuclear magnetic resonance (NMR). The sample can then be submerged in a predetermined volume of a weighing fluid and the mass of the fluid-saturated sample in the weighing fluid, mf is measured. Using the measured and determined values one can determine the volume of the sample, Vc, the bulk density of the sample, pb, the volume of the matrix, Vm,, and the matrix or grain density of the subsurface formation, pm.
(FR) L'invention concerne un procédé et un système pour déterminer la densité matricielle ou granulaire d'une formation souterraine. Ceci consiste à mesurer la masse dans l'air d'un échantillon saturé de fluide de la formation souterraine, la masse dans l'air comprenant la masse de l'échantillon, la masse d'un fluide entourant l'échantillon et la masse du fluide se trouvant à l'intérieur de l'échantillon. Le volume du fluide se trouvant à l'intérieur de l'échantillon (V ø) et le volume du fluide entourant l'échantillon (Vsur) sont déterminés par résonance magnétique nucléaire (RMN). L'échantillon peut ensuite être immergé dans un volume prédéterminé d'un fluide de pesage et la masse de l'échantillon saturé de fluide dans le fluide de pesage (mjis) est mesurée. En utilisant les valeurs mesurées et déterminées, on peut déterminer le volume de l'échantillon (Vc), la densité apparente de l'échantillon (,p b ), le volume de la matrice (V m ) et la densité matricielle ou granulaire de la formation souterraine (p m ).
