Terrestrial LIDAR data were acquired at four sites in the Acacus Formation in southwestern Libya in order to better understand the sedimentary architecture and to create outcrop models to aid ongoing subsurface exploration. The outcrop models comprise up to 8 individual scans merged to produce panels up to 1.2 km wide and c. 200 m high. The panels highlight the gross stratigraphic architecture including shallowing- and coarsening-upwards cycles, major channel bodies, and subtle prograding units. The scan resolution was chosen to resolve the bed-scale stacking that typifies hydrocarbon reservoirs in this formation. Surfaces and facies observed in the outcrops and constrained by the LIDAR data were then used to construct 2-D synthetic seismic panels of the outcrop. These models were parameterized with densities and velocities from subsurface examples and used to gain insight into the seismic resolution of depositional architecture.
