FORMATION ANALYSIS INCORPORATING IDENTIFICATION OF IMMOVABLE AND VISCOUS HYDROCARBONS

Methods and systems are provided for conducting formation analysis. Data from borehole logging tools is used to conduct a petrophysical analysis of the formation in order to determine (quantify) total porosity and formation matrix permittivity for an interval of the formation.

Abstract Methods and systems are provided for conducting formation analysis. Data from borehole logging tools is used to conduct a petrophysical analysis of the formation in order to determine (quantify) total porosity and formation matrix permittivity for an interval of the formation. Noninvaded zone water saturation and flushed zone water saturation for the interval of the formation is determined using a saturation model of the interval. The noninvaded zone water saturation is compared to the flushed zone water saturation, and the results of the comparison are used to determine that the interval of the formation contains movable hydrocarbon, immobile hydrocarbon or movable formation water. La présente invention concerne des procédés et des systèmes pour effectuer une analyse de formation. Des données provenant d'outils de diagraphie de trou de forage sont utilisées pour effectuer une analyse pétrophysique de la formation afin de déterminer (quantifier) la porosité totale et la permittivité de matrice de formation pour un intervalle de la formation. La saturation en eau de zone non envahie et la saturation en eau de zone rincée pour l'intervalle de la formation sont déterminées à l'aide d'un modèle de saturation de l'intervalle. La saturation en eau de zone non envahie est comparée à la saturation en eau de zone rincée, et les résultats de la comparaison sont utilisés pour déterminer si l'intervalle de la formation contient un hydrocarbure mobile, un hydrocarbure immobile ou de l'eau de formation mobile.
