B-13 A HIGH RESOLUTION NMR LOGGING TOOL – CONCEPT VALIDATION 1 JOACHIM TABARY¹ MARC FLEURY¹ MARCEL LOCATELLI² and JEAN-PIERRE MARTIN³ ¹Institut Français du Pétrole 1 & 4 Avenue du Bois Preau 92852 Rueil Malmaison France ²Laboratoire d’Electronique de Technologies et Instrumentation CEA/DTA ³Geo Energy Abstract The paper presents a pre-study of a new NMR logging tool having a vertical resolution of 2.5 cm much shorter than existing devices (from 30 cm up to 100 cm). Such a tool is especially dedicated to shaly formation and thin beds where the estimation of porosity and saturation is very difficult with resistivity logs.
