“…Studies that undertake palinspastic restoration of turbidite systems, which revises the geometry and dimensions of systems to the configuration during deposition, are rare and tend to be in small depocenters (e.g. Fernandez et al, 2004;Falivene et al, 2006;Paton et al, 2007;Aas et al 2010;Durand-Riard et al, 2011).…”

“…As the most accessible and photogenic exposures occur along the main road north from Ainsa (A138) show mainly MTCs between the Ainsa I and II fans, previous researchers have concluded that the stratigraphy comprises only channelised sandstones sandwiched between type Ia MTCs, leading to the interpretation that the Ainsa System is a slope-channel system (e.g., Fernandez, et al, 2004;Falivene, et al, 2006aFalivene, et al, , 2006bFalivene, et al, 2007;Bakke, et al, 2008). Mapping of the Ainsa System, however, shows that these much-visited sections represent base-of-slope parts of the Ainsa System where SGFs from an easterly source (present co-ordinates) entered the basin and turned into a more northerly direction on the proximal basin floor, at least for the Ainsa II and III fans, where basin-slope instability along the eastern basin margin has led to the deposition of base-of-slope deposits with fan lateral-margin deposits (Pickering and Corregidor, 2005).…”

“…In order to simulate facies heterogeneity and analyze uncertainty in reservoir models, stochastic methods are applied to predict rock properties at unsampled locations (Dubrule and Damsleth 2001). However, to simulate the facies heterogeneity in a geologic realistic manner, stochastic facies modelling algorithms need to be driven by accurate information on the depositional system (Falivene et al 2006). Quantitative data, such as geometry and distribution of sedimentary bodies (Figures 8 and 10), derived from DOMs provide conditioning data for the algorithms to populate realistic subsurface geocellular reservoir models.…”

Applications of digital outcrop models: two fluvial case studies from the Triassic Wolfville Fm., Canada and Oukaimeden Sandstone Fm., Morocco

The application and benefits of employing digital outcrop models (DOMs) are discussed using two Triassic fluvial case studies to demonstrate data collection and integration methods. Developments in data analysis techniques are examined to demonstrate their utility for collecting meaningful and reliable statistical information needed to build realistic stochastic reservoir models. To establish a significant geostatistical dataset a large number of accurate observations are required. It is difficult to get the necessary statistics using subsurface data alone, due to the limited resolution and/or areal coverage of respectively seismic and well data. Outcrop studies are, therefore, commonly utilized to provide analogue statistical information (e.g. channel width, length, thickness and thickness vs. width ratio). Traditional data collection methods used in the field are however largely restricted to areas with (easy) physical access, or using remote observations with limited accuracy, such as photographic methods.Digital data collection techniques such as LiDAR (Light Detection and Ranging) and differential GPS allow more accurate measurements, as well as from previously inaccessible locations, to be taken of sedimentary architecture. The technique generates much larger volumes of measurements, as the area from which accurate data can be extracted is increased. This offers a more meaningful statistical dataset, hence reducing uncertainty in the final reservoir model.Both case studies, the Oukaimeden Sandstone Formation (OSF), Morocco and Wolfville Formation, Canada, are from Late Triassic braided fluvial systems. The OSF dataset has been used to illustrate how geometric information of channel width versus thickness relationships (W:T) are collected using a projection plane technique. The results show W:T variations between 3.49:1 in the Lower Oukaimeden member, 1.54:1 in the Middle Oukaimeden member and 3.75:1 in the Upper Oukaimeden member, demonstrating the observed architectural evolution of the fluvial system. The Wolfville Formation case study shows how DGPS in combination with LiDAR data has been used to more accurately map faults to obtain statistical information on fault orientation (NE-SW) and length (mean ¼ 38.3 m and median ¼ 18.2 m). Another applied analysis technique utilizes a facies classified point-cloud to aid surface correlations between sedimentary logs and construct a log based correlation panel from which estimates of facies frequencies are derived.
