Figure 13
Maps and cross sections illustrating models of stacked delta-lobe deposits that either have zero vertical permeability or non-zero vertical permeability in distal delta-front facies in the presence of a 90% barrier to flow along clinoforms, in models that either (left) lack or (right) contain channelized fluvial sandbodies (FC). (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–D. (B) Depositional-dip-oriented cross section 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, D) Depositional-dip-oriented cross section showing water saturation after 20 yr of production, with a target oil production rate over 20 yr of
(2200 bbl/day), where there is (C) zero vertical permeability in dDF deposits and (D) non-zero vertical permeability (
of 7 md) in dDF deposits. Sweep is improved locally in the models containing low vertical permeability (
of 7 md) in dDF deposits. DC = distributary channel sandstones; SMB = stream-mouth-bar sandstones; pDF = proximal delta-front sandstones; dDF = distal delta-front heteroliths.
