Traps are the product of the interaction of many geologic elements and processes. The outcome of all the possible combinations of geologic elements makes each trap unique. Yet each trap generally shares enough similarities with other traps in the same basin or in other basins that traps may be classified. The classification chosen depends on one’s purpose. The ultimate purpose of the trap classification presented in this chapter is to facilitate the discovery of oil and gas accumulations. This chapter discusses the philosophy of classification, shows how to classify traps in a scientifically rigorous and systematic way, and presents a classification scheme for traps found to date. The classification scheme is designed to be flexible and therefore will evolve as new trap types are found and trapping concepts change.
Classification philosophy
Most petroleum geologists classify traps according to the scheme proposed by Levorsen.[1] Levorsen’s scheme breaks traps into three basic types: structural, stratigraphic, and combination. The trap classification scheme proposed here uses Levorsen’s scheme as a foundation and adds new trap types discovered since 1954. The proposed scheme attempts to formalize the schemes of Levorsen and others (Rittenhouse, 1972[2]; North, 1985[3]; Melton and Bertram, 1992[4]; and Biddle and Weilchowsky, 1994[5]) by developing a more systematic and rigorous approach. It uses elements critical to petroleum exploration to group traps into levels. The method is similar to the one used by biologists to classify plants and animals.
