The Permian–Triassic Khuff Formation is considered to be the most prolific for the natural gas production in the world. The Khuff reservoirs exhibit vertical and lateral heterogeneities which cannot be fully captured within the interwell spacing from the subsurface data. The Upper Khartam Member in central Saudi Arabia represents an excellent outcrop analog for the upper parts of Khuff-B and the whole Khuff-A reservoirs. The main objective of this study is to reconstruct digital outcrop model of the Upper Khartam Member. This study included sedimentological data and digital laser scanning modeling. Four stratigraphic sections were measured to cover the whole outcrop of Upper Khartam, and a composite section was constructed. The investigations revealed that the studied outcrop of Upper Khartam comprises six lithofacies associations deposited in three depositional settings: offshore (deep–shallow subtidal zone), foreshoal, and shoal complex. The terrestrial laser scanner was used to scan the outcrop from four different scan positions. The Polyworks software was used for the processing and to produce the photorealistic model for Upper Khartam. ArcGIS combined with the Geo Analysis Tool was utilized to interpret the digital models. The digital modeling allows accurate structural and statistical measurements of lithofacies and integrated with the traditional field data on it and examined the lateral continuity and the architecture of the strata in the outcrop. Also, the model revealed the architecture and the continuity of the reservoir units as well as the barriers or the non-reservoir units within the studied outcrop. The integration of the results of this work with subsurface data might help to provide better understanding and prediction of the quality of Khuff reservoirs in the subsurface.
