Robust Incorporation of Well Control for Improving Seismic Processing and Inversion

D026 Robust Incorporation of Well Control for Improving Seismic Processing and Inversion J.K. Washbourne* (Chevron Energy Technology Co.) & E.F. Herkenhoff (Chevron Energy Technology Co.) SUMMARY We present a method for utilizing well log information to measure the quality of seismic AVO inversions. The central contribution is the construction of a “cost function” that measures inversion quality by comparing statistical relationships among inverted reflectivities with analogues from well control reflectivities. Given this cost function we can optimize the AVO inversions as well as the parameters of upstream processing tools. EAGE 69 th Conference & Exhibition — London UK 11 -
