f Linearized target-oriented inversion - Application to real data

We apply our linearized target oriented inversion scheme (Bernasconi et al., 1994) to the Mobil data set (Keys and Foster, 1995). The seismic line consists of 1001 shot records. Each shot record was recorded on 120 channels for six seconds. Two wells (well A and well B) intersect the seismic line. Well log data are available. We have selected a target zone located at a depth of 2 km, centred on CDP 808 (well A) where an increase in oil content is evident.(Fig 1). Processing is limited to a corresponding portion of the whole data set, ranging from CDP 660 to CDP 1130. It covers an horizontal range of 5875 m.
