Title
(EN) RECONFIGURABLE WELL LOGGING SYSTEM
(FR) SYSTEME DE DIAGRAPHIE DE SONDAGE RECONFIGURABLE
Abstract
(EN)
A method and apparatus for producing a reconfigurable well-logging data acquisition and interpretation system for performing a plurality of discrete data processing functions and which achieves a level of system reliability approximating that of a redundant system, but without total hardware redundancy.
(FR)
L'invention concerne un procédé et un appareil de production d'un système d'acquisition et d'interprétation de données de diagraphie de sondage reconfigurable pour effectuer plusieurs fonctions de traitement de données discrètes et permettant d'atteindre un niveau de fiabilité du système approchant celle d'un système redondant mais sans une redondance totale du 'hardware' (équipement).
