ABSTRACT: Outcrop Characterization with Digital Geologic Mapping

Throughout the typical exploration and production workflow, petroleum geologists apply their experience with outcrop analogs to gain a better understanding of the subsurface Previous HitdataNext Hit they are currently interpreting. A fundamental problem of outcrop studies is how to capture the inherent three-dimensionality of sedimentary bodies, stratigraphic units, and structural features in a quantitative fashion. "Digital Geology" offers a new approach to the collection and visualization of quantitative geologic Previous HitfieldNext Hit Previous HitdataNext Hit by incorporating modern surveying technologies and 3D visualization into the traditional outcrop characterization workflow. Although the specific techniques vary between datasets, the common theme of digital geology Previous HitfieldNext Hit campaigns is that the geologic Previous HitdataNext Hit are collected in conjunction with highly accurate spatial information along with their specific geologic attributes. This spatial context allows the inherent three-dimensional nature of outcrop Previous HitdataNext Hit to be used to gain a better understanding of the geometry and properties of key geological features and bodies and the geologic processes that allowed it to form. These digital surveying techniques allow geological Previous HitdataNext Hit to be quantified. Spatial context also allows outcrop Previous HitdataNext Hit sets to be placed in a 3D viewing canvas and directly compared to common exploration and production Previous HitdataNext Hit such as cores, well logs, and seismic Previous HitdataNext Hit. Previous HitExamplesNext Hit of stratigraphic and structural outcrop analogs that we have been collected using digital geology will be shown as demonstrations in the techniques of Previous HitdataTop capture and visualization.
