I022 Z-99 RIGHT-TIME WELL AND LOOK-AHEAD POSITIONING USING SEISMIC TRAVELTIME DATA Abstract JO EIDSVIK and KETIL HOKSTAD Statoil Research Centre Trondheim Norway Since the processing and data transfer capacity is highly limited in while drilling operations it is important to evaluate the information content of different data sources. We focus on the analysis of seismic traveltime data acquired in the borehole in particular the use of traveltime picks for well geosteering. The Bayesian methodology that we propose is applicable to both forward VSP (receivers in well) and reverse VSP (Drill-bit noise). Traveltime picks are shown to be informative of well
