It is well known that often no single geophysical measurement can provide all of the information required to address a reservoir exploration, appraisal or management problem. All methods have strengths and weaknesses. Seismic data, for example provide high resolution of structure and stratigraphy, however on occasion the unambiguous interpretation of lithology or fluid properties can be challenging. Controlled source electromagnetic (CSEM) data allow resistivity to me mapped remotely, potentially providing better constraint on fluid properties, however with poor structural resolution (see Constable, 2010 for a review of CSEM technology). Well log data provide high resolution measurements of rock and fluid properties however these are only available at the well bore, and geophysical measurements must be used to interpret how these properties vary away from the well. Integration of multiple geophysical data types allows the strengths of each to be exploited, to address ambiguities inherent in the interpretation of any one taken by itself (e.g. MacGregor, 2012, Gao et al, 2012, Harris et al, 2009).
