USE OF COMBINED SEISMIC INVERSION AND HFI DATA TO EVALUATE A CHALK PROSPECT Abstract 1 AUTHORS 1 2 1 E. TORGERSEN J. MOE K. R. VAGLE Address 1 ConocoPhillips Exploration Scandinavia P.O. Box 220 N-4098 Tanager Norway 2 Ødegaard Norge A/S Norway In between two exploration wells a four-way closure was identified partly associated with a seismic amplitude anomaly at the Top Ekofisk Fm. Nearby wells had not penetrated the upper part of the Chalk Group with the same or comparable seismic characteristic. The possibility that the undrilled event was associated with clastic sediments was not neglected. The seismic characteristics
