The methodology of seismic-facies analysis is illustrated for a Pliocene-Pleistocene lowstand depositional system in South Ship Shoal and Ewing Banks areas, offshore Louisiana. Sequence stratigraphy and seismic-facies analysis were used to assess the results of six existing wells and formulate recommendations for additional wells. A sedimentologic model, based on log and sidewall core calibration of seismic facies, was used to predict both lithofacies and hydrocarbon occurrence in undrilled areas. Three new wells drilled in 1987 confirmed both sedimentologic and hydrocarbon predictions with the drilling of 100 percent mudstone sections in two wells, and the presence of hydrocarbon bearing sandstones within a synclinal area of OCS Block Ewing Bank 988.
