Title (EN) METHOD FOR ESTIMATING ROCK PETROPHYSICAL PARAMETERS USING TEMPERATURE MODIFIED NMR DATA
(FR) PROCEDE D'ESTIMATION DE PARAMETRES PETROPHYSIQUES DE ROCHES FAISANT INTERVENIR DES DONNEES RMN MODIFIEES EN TEMPERATURE
Abstract: front page image
(EN)Carbonate formations yield unreliable, down hole NMR results. Inter alia, these results must be corrected for temperature. The invention features several methods for obtaining more reliable NMR results for rock petrophysical parameters in carbonate rock formations based upon adjusting T?2¿ data with respect to temperature.
(FR)Les formations de carbonate donnent des résultats RMN de fond de puits peu fiables. Lesdits résultats doivent, entre autres, être corrigés en température. L'invention concerne donc plusieurs procédés permettant d'obtenir des résultats RMN plus fiables à propos des paramètres pétrophysiques des roches dans les formations rocheuses constituées de carbonate, procédés qui sont basés sur l'ajustement des données T?2¿ en fonction de la température.
