Figure 11
Maps and cross sections illustrating models of stacked delta-lobe deposits that either (left) lack or (right) contain channelized fluvial sandbodies (FC) that erode down from overlying coastal-plain deposits. (A) Maps of facies-association belts near the top of the models (parasequence 1.7, Figure 3D, with the overlying coastal-plain deposits shown in Figure 3E removed), showing location of injection and production wells and the cross sections illustrated in parts B–E. (B) Depositional-dip-oriented cross sections showing the internal facies architecture of the modeled parasequences with barriers covering 90% of each clinoform (black lines) and parasequence-bounding flooding surfaces (dashed lines). (C) Corresponding cross section showing water saturation after 10 yr of production with a target oil production rate over 10 yr of 
(2200 bbl/day). Sweep is improved locally in the model containing FC sandbodies (right). (D) Depositional-dip-oriented cross sections showing the internal facies architecture of the modeled parasequences with barriers covering 90% of each clinoform (black lines) and parasequence-bounding flooding surfaces (dashed lines). Note that barriers near the top of the clinoforms (left) have been replaced by FC sandbodies (right). (E) Corresponding cross section showing water saturation after 10 yr of production. Sweep is improved, and earlier water breakthrough occurs locally in the model containing FC sandbodies (right). DC = distributary channel sandstones; SMB = stream-mouth-bar sandstones; pDF = proximal delta-front sandstones; dDF = distal delta-front heteroliths; PD = prodelta shales.
