 BP’s active Previous HitexplorationNext Hit of several deep-water slope basins presents recurring Previous HitexplorationNext Hit risks which are being addressed partly through integrated Previous HitstructuralNext Hit-geological interpretation and modelling.

The large prospective structures which are frequently developed in the ‘down-dip’ compressional-toe regions of the Gulf of Mexico and Amazon deep-water environments have been generated by gravitational movement of the entire slope basin, which in the Gulf of Mexico has involved substantial synchronous salt flow.

This presentation is focused on key elements of the Previous HitstructuralNext Hit Previous HitworkflowNext Hit, integration between Previous HitstructuralNext Hit interpretation and basin modelling, and the resultant contribution to risk reduction which has been applied recently during Previous HitexplorationNext Hit of these basins.

Key Previous HitexplorationNext Hit-scale issues include crustal structure, heat flow, source presence, trap geometry and complexity prediction in sub-salt settings, and palaeo-Previous HitstructuralNext Hit impact on charge history and depositional system evolution. A selection of examples will be presented which illustrate application of Previous HitexplorationNext Hit-scale Previous HitstructuralNext Hit Previous HitworkflowNext Hit prior to recent field discovery and during ongoing appraisal within the Gulf of Mexico, and during early Previous HitexplorationTop in the Amazon slope basin.
