Quantifying Facies Attributes of the Caicos Platform

Abstract Modern analogs such as Caicos Platform can play an important role as conceptual facies models for characterization of a hydrocarbon reservoir, and also provide facies attribute information to be used as input in building reservoir models. In an attempt to gather such valuable data, the attributes for key reef-associated facies of the Caicos Platform are assessed from a Landsat image through facies mapping. Some key findings are: reef and reef apron occupy a smaller percentage of large platforms like Caicos than smaller ones, reefs seem to be patchier than aprons, fully aggraded reefs become somewhat wider as their length increases, reef width and apron width are directly related, and probabilities can be set for expected dimensions of reef and apron width.
