Paper Summary
A comprehensive rock physics and AVO feasibility study, where we combine burial and rock physics modelling, has been conducted for the Tablelands and North Tablelands area, offshore Newfoundland. The burial history was assessed in 3D from seismic velocity information, calibrated to selected wells in the area. There is a natural ambiguity between the temperature and burial histories. We therefore introduce the term pseudo-uplift referring to deviations from normal compaction for a given temperature gradient. The pseudo-uplift cube can be used to constrain 3D rock physics and AVO feasibilities away from the selected wells within a selected area of interest. We model different scenarios, including a pessimistic one (P90) with respect to reservoir quality and fluid sensitivity, an optimistic one (P10), and an expected one (P50). These AVO scenario-cubes could be used to screen, rank and derisk leads and prospects in the area from real AVO data.
