Interpretation of PP and PS seismic data from the White Rose oilfield, offshore Newfoundland

Jessica Maria Jaramillo Sarasty, Robert R. Stewart

During the summer of 2002, an ocean-bottom seismometer test line was conducted over Husky Energy Inc.'s L-08 well in the White Rose oilfield, offshore Newfoundland. The Avalon reservoir at the White Rose field is difficult to image using conventional marine seismic. Therefore, a 21-seismometer/hydrophone ocean-bottom test was recorded from an airgun source. The correlation between the PP and PS synthetics from well L-08 and the OBS data (vertical and radial components) gave confidence to the interpretation of the resultant PP and PS seismic sections. After matching both radial and vertical component seismic sections, the events on both sections are clear. The Vp/Vs values obtained from the seismic are related to the values from the well L-08. There are some Vp/Vs anomalies going laterally on the seismic sections. In general, the values decrease with depth.
