Analyzing Dune Foreset Cyclicity In Outcrop With Photogrammetry

Contribution of drone photogrammetry to 3D outcrop modeling of facies, porosity, and permeability heterogeneities in carbonate reservoirs (Paris Basin, Middle Jurassic)

“…The development of drone photogrammetry in recent years has eased the quantitative analysis of geological outcrops, even along cliff faces (Schmitz et al, 2014;Cabello et al, 2018;Rubi et al, 2018;Nesbit et al, 2018;Siddiqui et al, 2019). However, most of these digital meter-scale resolution captures were applied to sandstone outcrops (e.g., Hayes et al, 2017;Cabello et al, 2018;Rubi et al, 2018). While geological photogrammetric models exist, complete static geological models including distribution of properties like porosity and permeability in complex sedimentary systems have not yet been created in limestones using these technologies (Madjid et al, 2018;Marques et al, 2020).…”

Resolving stratigraphic architecture and constraining ages of paralic strata in a low‐accommodation setting, Firebag Tributary, McMurray Formation, Canada

“…The formation comprises a wide array of sedimentary deposits, including cross‐stratified sandstones, coals and pedogenically altered mudstones, and a variety of heterolithic facies (Carrigy, 1959; Keith et al, 1988; Mossop & Flach, 1983; Rinke‐Hardekopf et al, 2019). From the bottom to the top of the stratigraphic succession of the McMurray Formation, heterolithic deposits preferentially exhibit sedimentary structures characteristic of fluvial, tidal and wave influence (Château et al, 2021; Hayes et al, 2017; Hein & Cotterill, 2006; Timmer et al, 2016; Weleschuk & Dashtgard, 2019). The ichnology and palynology of McMurray Formation strata also indicate deposition in freshwater through to brackish‐water environments (Baniak & Kingsmith, 2018; Fustic et al, 2012; Gingras et al, 2016; Harris et al, 2016; Hubbard et al, 2011; La Croix et al, 2019, 2020; Mossop & Flach, 1983; Pemberton et al, 1982; Ranger & Pemberton, 1997; Shchepetkina et al, 2016).…”
