Inversion of SBL Data Acquired in Shallow Waters

E020 INVERSION OF SBL DATA ACQUIRED IN SHALLOW WATERS Introduction 1 The Sea Bed Logging (SBL) method is described by Eidesmo et al. (2002). The main idea is to use an active source to probe the underground for thin high resistive layers. Hydrocarbon filled reservoirs will typically have a resistivity that is one to two orders of magnitude higher than a water filled reservoir. It will also have a resistivity that is one to two orders of magnitude higher than the surrounding shale or mudrock and this is sufficient to support a partially guided wave that will leak energy up
