Understanding Deep-Water Architecture from Process Interpretation from Outcrop: Details Provide the Difference

Outcrops provide vital information for understanding both modern and ancient deep-water sedimentary systems. Still, interpretation of plan view geometries in outcrops is challenging and usually ambiguous, in contrast to in 3D seismic, where deep-water architecture is readily observed. Attention to classic details such as paleocurrents, bed thickness changes and geometries, and bed stacking is vital to understand processes and architecture in outcrops. Classic outcrops such as the Ainsa system of Spain and the Ross and Gull Island Formations of western Ireland show that both subtle and larger differences in processes cause substantial changes in interpreted architecture between channels and channel-realted lobes. The talk focuses on how these key observations can be transferred to subsurface settings where population of seismic geometries with detailed process understanding is vital for exploration and production.
