Abstract

Highly compartmentalized reservoirs are commonly attributed to heterogeneous facies as well as vertical/horizontal stratigraphic trends associated with depositional cycles. Detailed information on stratigraphic heterogeneity is essential to fully exploit a reservoir. Subseismic-scale reservoir stratigraphy can be investigated in outcrop by integrating multiple high-resolution sedimentological data, lidar (light detection and ranging) data, and GPR (ground-penetrating radar) data. This combination of different data sets can help to characterize ancient tidal channels exposed in outcrops, which are considered to be heterogeneous compartmentalized sandstone reservoir analogs. This multidisciplinary approach not only attempts to describe rarely seen Cretaceous tidal-channel deposits at the Dry Wash outcrop (Figure 1) in three dimensions, but it also demonstrates how the different types of data can be integrated to better understand ancient complex shallow-marine depositional systems.
