Using Outcrop Analogs to Improve 3D Heterogeneity Modeling of Brazilian Sand-Rich Turbidite Reservoirs

Controls on reservoir distribution, architecture and stratigraphic trapping in slope settings

“…Probably most the representative of them comes from the Carapeda field, Campos basin, Brazil (Smith, 2002, personal communication). Reservoirs in Carapeda field are confined to a NNW-SSE to WNW-ESE oriented troughs on the slope resulting from subsidence along listric faults (Moraes, Becker, Monteiro, & Netto, 2000). The Carapeda reservoirs are laterally continuous, high net-to-gross sheet and channel complexes with elements that show thinning-upward patterns related to evolution from confined to unconfined deposition (Moraes et al, 2000).…”

Deep-water sedimentation in the Alpine Foreland Basin of SE France: New perspectives on the Grès d’Annot and related systems—an introduction

“…The GrOs d'Annot has frequently been used as an analogue for sand-rich turbidite hydrocarbon fields where topographic control has played a key role in defining the reservoir bodies, like in the North Sea (e.g. Gannet fields and Gryphon field; Newman et al 1993) or on the Brazilian margin (Campos basin; Moraes et al 2000).…”

Sedimentology and reservoir modelling of the Ormen Lange field, mid Norway

“…The datasets range from examples with extremely low mean apparent shale lengths (Kleverlaan & Cossey, 1993) to others, such as the Grès d'Annot, containing far more laterally extensive shale bodies (e.g. Moraes et al, 2000). Mean apparent lengths in sections parallel to palaeocurrents have often been found to be approximately two to four times the mean apparent lengths in sections perpendicular to palaeocurrents.…”

“…Joseph et al, 2000;Moraes, Becker, Monteiro, & Netto, 2000;Rozman, 2000;Stephen, Clark, & Gardiner, 2001). In reservoir modelling they are typically treated as discontinuous ellipsoids within a continuous sandstone background, but Stephen et al (2001) make the point that in some cases amalgamation surfaces may represent holes in continuous mudstone sheets.…”
