Outcrop analog studies are commonly used in the oil and gas industry to better constrain subsurface geometries and facies heterogeneity distribution. Coupled with field data, drone-based photogrammetric models bring key value to outcrop analog studies for reservoir characterization. In the scope of referencing world class outcrop analogs for hydrocarbon exploration and production, we launched a series of 3D acquisitions on several outcrop analogs in different sedimentological settings. The paper describes the workflow steps applied on a specific case study, from the acquisition of photogrammetric data to geological interpretation. The study area is the Aptian carbonate platform to basin transition of the Maestrat Basin (Spain), which is considered as a world class reference analog of the productive Shuaiba Formation in the Middle East.
