Integration of regional to outcrop digital data: 3D visualisation of multi-scale geological models
Calibration and validation of reservoir models: the importance of high resolution, quantitative outcrop analogues
Rapidly developing methods of digital acquisition, visualization and analysis allow highly detailed outcrop models to be constructed, and used as analogues to provide quantitative information about sedimentological and structural architectures from reservoir to subseismic scales of observation. Terrestrial laser-scanning (lidar) and high precision Real-Time Kinematic GPS are key survey technologies for data acquisition. 3D visualization…
Read MoreExtending Virtual Outcrop Geology into the Subsurface – Combining Terrestrial Laser Scanning and Ground Penetrating Radar at the Bridge of Ross, Co. Clare
Modern field methods of digital data acquisition can record surface geology in unprecedented detail, and allow spatially precise, photo-realistic virtual copies of the outcrop to be constructed. Terrestrial laser scanning (LIDAR) and differential GPS are key technologies. 3D visualisation of the virtual outcrop (using standard desktop computers or high-end immersive systems) helps to increase overall…
Read MoreA cost-efficient solution to true color terrestrial laser scanning
This paper presents a low-cost true color terrestrial laser scanning system, described in terms of the hardware and software elements necessary to add color capability to existing non-color laser scanners. A purpose-built camera mount allows a digital camera to be positioned coincident and collinear with the beam detector of the laser scanner device, such that…

Using geological rules and terrestrial laser scanning datasets to constrain uncertainty in three-dimensional structural models of sub-seismic scale fault networks
Quantifying Fault Attributes at the Outcrop Scale: a Fault Network Model of Sub-Seismic Normal Faults in a Thinly-Bedded Reservoir Sequence
Three-dimensional (3D) seismic reflection data have revolutionized our knowledge of fault attributes in sedimentary basins. However, the resolution of such data is limited – faults with throws
Read MoreCapturing Detailed Outcrop Geology Using Terrestrial Laser Scanning (Lidar) and Other Digital Technologies: Current Status and Future Directions
Geospatial data acquisition at global to regional scales has wide acceptance, and tools such as Google Earth have been instrumental in extending Earth visualisation far beyond specialist users of GIS and satellite imagery. At the outcrop scale, the number of industry and academic geoscientists adopting digital technologies to gather field data is steadily increasing. When…
