Each systems tract—highstand, lowstand, and transgressive—has a different trapping potential based on the vertical and lateral distribution of lithofacies deposited within specific depositional environments. White<ref name=ch04r112>White, D., A., 1980, Assessing oil and gas plays in facies-cycles wedges: AAPG Bulletin, vol. 64, p. 1158–1178.</ref> presents an excellent review of trap types within facies-cycle wedges, which are related to transgressive-regressive cycles and can be related most specifically to the transgressive systems tract and the highstand systems tract. In White's classification, prograding lithofacies of the lowstand systems tract might occur as subunconformity traps or might be mistakenly identified as highstand systems tract deposits. Gravity-flow deposits of slope and basin-floor fan systems are most often placed into the lowstand systems tract because they are deposited basinward of the shelf/slope inflection.

Only siliciclastic systems, similar to those of the Cenozoic of the central and western Gulf of Mexico, are discussed here.
