Title (EN) STRENGTH (UCS) OF CARBONATES USING COMPRESSIONAL AND SHEAR ACOUSTIC VELOCITIES
(FR) DÉTERMINATION DE LA SOLIDITÉ (UCS) DE CARBONATES AU MOYEN DES VITESSES ACOUSTIQUES DE COMPRESSION ET DE CISAILLEMENT
Abstract: front page image
(EN)Acoustic velocities measured downhole are used to predict a rock strength using results of a regression analysis that include grain size. The grain size can be obtained from drill cuttings or from NMR measurements. The determined rock strength is used in drilling operations.
(FR)L'invention concerne un procédé permettant de prédire la solidité d'une roche grâce aux vitesses du son mesurées en profondeur. Le procédé utilise les résultats d'une analyse de régression qui inclut la taille des grains. La taille des grains peut être obtenue par l'analyse des déblais de forage ou par des mesures RMN. La solidité déterminée de la roche est utilisée dans des opérations de forage.
