Title
(EN) METHOD OF ASSESSING HYDROCARBON SOURCE ROCK CANDIDATE
(FR) PROCÉDÉ D'ÉVALUATION D'UNE ROCHE MÈRE D'HYDROCARBURES CANDIDATE
Abstract
(EN)
A method of assessing a hydrocarbon source rock candidate uses seismic data for a region of the Earth. The data are analysed to determine the presence, thickness and lateral extent of candidate source rock based on the knowledge of the seismic behaviour of hydrocarbon source rocks. An estimate is provided of the organic content of the candidate source rock from acoustic impedance. An estimate of the hydrocarbon generation potential of the candidate source rock is then provided from the thickness and lateral extent of the candidate source rock and from the estimate of the organic content.
(FR)
Selon l'invention, un procédé d'évaluation d'une roche mère d'hydrocarbures candidate utilise des données sismiques d'une région de la terre. Les données sont analysées pour déterminer la présence, l'épaisseur et l'étendue latérale de la roche mère candidate sur la base de la connaissance du comportement sismique des roches mères d'hydrocarbures. À partir de l'impédance acoustique, une estimation du contenu organique de la roche mère candidate est obtenue. Une estimation du potentiel de génération d'hydrocarbures de la roche mère candidate est ensuite fournie à partir de l'épaisseur et de l'étendue latérale de la roche mère candidate et de l'estimation du contenu organique.
