Quantitative Use of Pre-Stack Timelapse Seismic for Production History Matching

1 N-09 QUANTITATIVE USE OF PRE-STACK TIME- LAPSE SEISMIC FOR PRODUCTION HISTORY MATCHING PETER ROWBOTHAM PAUL WILLIAMSON DOMINIQUE MARION GAEL JANEX and OLIVIER GOSSELIN TotalFinaElf Exploration UK plc Geoscience Research Centre 33 Cavendish Square London W1G OPW UK Abstract In recent years we have witnessed impressive advances in the use of time-lapse seismic data for reservoir management. Most examples have used the seismic in a qualitative or at best semiquantitative manner typically highlighting zones of drainage through TL difference maps. Here we advocate quantitative use of seismic data in the production history matching process through high-resolution inversion of pre-stack depth
