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

This study showcases the value of drone photogrammetry in creating a meter-scale geological model complex carbonate geobodies. Although is now commonly used for modeling sedimentary facies and architecture sandstone outcrops, its use not widespread geomodels Drone can generate accurate line-drawing correlation detailed analysis along inaccessible vertical faces outcrops permits observations unreachable places. work models Bathonian limestones Massangis quarry (Burgundy) as an example. The covers area 0.4 km2 considered analogue Oolithe Blanche geothermal reservoir center Paris Basin. represents good microporosity secondary porosity associated with dedolomitization.
