f Detailed reservoir description by integration of well and 3D seismic data

Temporal and lateral resolution of seismic data is principally determined bv the shape and duration of the propagating wavelet. Its accurate estimation and the ability to change its shape are both of paramount importance to achieve the maximum resolution afforded by the available bandwidth. An integrated multi-line, multi-well wavelet estimation and shaping procedure was performed at Heidrun field, located offshore Norway and operated by Conoco Norway, Inc. The procedure, a proprietary technique known as space adaptive wavelet processing, involves borehole analysis, extraction of wavelets at well locations and performs implicit spectral inversion to condition the seismic pulse to a common, broad band, zero phase wavelet.
