A Sea Bed Logging (SBL) Calibration Survey over the Troll Gas Field

E019 A SEA BED LOGGING (SBL) CALIBRATION SURVEY OVER THE TROLL GAS FIELD Introduction 1 Remote resistivity sensing of buried resistive layers in conductive sediments a concept called Sea Bed Logging (SBL - Pat. No. US 6.628.119 B1) has been demonstrated both theoretically by Kong et al. (2002) and Eidesmo et al. (2001) and by calibration surveys over a known oil field offshore Angola (Ellingsrud et al. 2002) and the Ormen Lange gas field offshore Norway (Røsten et al. 2003). These surveys were acquired in deep water areas (> 1000 m) to minimize the background return signal from the air-water
