Abstract
D044 Influence of Temperature on the Seabed Logging Response for a Sand-Shale Reservoir Z. Wang* (University of Oslo) L.J. Gelius (University of Oslo) & F.N. Kong (Norwegian Geotechnical Institute) SUMMARY Seabed logging (SBL) is a remote sensing EM technique with the potential of being a direct hydrocarbon indicator in marine environments. Temperature has a profound positive influence on both the conductivity of the pore fluid and the mobility of the counter-ions of clay in a water-saturated sand-shale reservoir. This paper first illustrates the influence of the temperature on the formation resistivity of different types of sand-shale reservoirs.Secondly the change in
