Hybrid-type Deepwater Reservoirs and Pitfalls in the Interpretation of Deepwater Sandstones

January 01, 2004


This chapter summarizes two important but unrelated aspects of deepwater settings: (1) various “hybrid-type” reservoirs and (2) pitfalls in interpreting deepwater reservoirs.

Reservoirs are considered to be hybrids if they do not easily fit into the classification of channel fills, thin beds in levees, sheets, and mass-transport complexes (Chapters 47). Hybrid reservoirs were influenced by gravity flows during one part of their formation and were deformed or resedimented after primary deposition.

Three kinds of hybrid reservoirs are reviewed briefly. In the first group, reservoirs were modified later by structural processes (remobilized sands). A second group of hybrid reservoirs comprises chalks that experienced resedimentation after their original pelagic deposition (e.g., southern North Sea chalks). A third group of hybrid reservoirs consists of carbonate debris aprons.

Finally, we briefly review some pitfalls involved in interpreting deep-water reservoirs using different data sets.
