Stochastic flow unit modelling of a North Sea coastal-deltaic reservoir

Modelling facies belt distribution in fan deltas coupling sequence stratigraphy and geostatistics: The Eocene Sant Llorenç del Munt example (Ebro foreland basin, NE Spain)

“…From the basic pixel-based methods such as the truncated Gaussian simulation used by Matheron et al (1987) and Ravenne et al (1990), to the more complex combinations involving sequence stratigraphic subdivision and pixel-based methods (Cook et al, 1999;Larue and Legarre, 2004), both also combined with object-based methods (MacDonald et al, 1992), or coupling deterministic interwell correlations with object-based approaches (Ainsworth, 2005). Jian et al (2002) also Fig.…”

“…Recently, geocellular models comparable to those built from subsurface reservoirs (MacDonald et al, 1992;Jian et al, 2002;Smith and Møller, 2003;Castellini et al, 2003;Svanes et al, 2004;Ainsworth, 2005;Larue and Friedmann, 2005) have been built from outcrops (Novakovic et al, 2002;Ravenne, 2002;Falivene et al, 2006c). This has proved to be an extremely useful technique to improve subsurface facies modelling approaches.…”

“…Shoreface and deltaic shallow-marine depositional systems make important reservoirs throughout the World, and consequently they have been the topic of numerous modelling studies (MacDonald et al, 1992;Hodgetts et al, 2001;Jian et al, 2002;Castellini et al, 2003;Li and White, 2003;Noad, 2004;Larue and Legarre, 2004;Ainsworth, 2005;Howell et al, 2008a). From a modelling perspective, fan deltas are a class of shallow-marine system that is less well studied, although locally they constitute important reservoirs.…”

Integration of digital outcrop models (DOMs) and high resolution sedimentology – workflow and implications for geological modelling: Oukaimeden Sandstone Formation, High Atlas (Morocco)

“…During the appraisal phase, geological models become the foundation of a reservoir management workflow designed for efficient recovery of reserves (Lake & Carroll 1986;Dubrule 1989;Haldorsen & Damsleth 1990;Srivastava 1994;North & Taylor 1996;Damsleth & Omre 1997;Falivene et al 2006). Understanding the precise architecture of sandbodies and intercalated shale baffles and barriers represents an essential piece of information within the workflow (MacDonald et al 1992;Dreyer et al 1993;MacDonald & Halland 1993;Jones et al 1995;Labourdette & Jones 2007). Traditional datasets used in reservoir modelling (i.e.…”
