oa Use of a 3D VSP for Reservoir Characterization and Property Estimation

Recent drilling success in a thin, unpredictable, yet prolific gas reservoir led to the acquisition<br>of a 3D Vertical Seismic Profile (VSP). The intent of the VSP was to generate a seismic<br>volume similar to the result of a traditional surface acquisition, but with frequencies in excess<br>of 100 Hz to increase vertical resolution. Raw field data contained coherent energy to 130 Hz,<br>and processing to date is encouraging.
