Digital Outcrop Imagery

RPS is developing 3D Digital Outcrop Models to augment existing training materials. The aim of this is to enhance the understanding of reservoir analogues as seen in outcrop examples. Imagery captured by an Unmanned Aerial Vehicle (UAV or drone) is processed into 3D models and orthomosaics that can be used in conjunction with high-definition video and other imagery on our training courses. Specifically, the new perspectives and observations available through the use of models and video can improve and deepen understanding in the following ways:

Clarification of complex or obscure relationships - features that cannot be seen in true strike or dip view in the field can be clearly picked out through the use of these images. Complex geometries can much more easily understood by the ability to rotate and view from multiple angles.

New perspectives - the ability to view outcrops from new, elevated or aerial perspectives can provide much greater insights into outcrop structure and architecture.

Scale - the models and associated videos truly help bridge the scale gap. Models can be rapidly examined and interrogated from a seismic scale to a bed or even lamination scale.

Access - outcrops that cannot be accessed for reasons of adverse weather, tides, safety or permission can be examined with the models.

Alternative analogues - These models can provide multiple alternative analogues to complement those viewed on field courses to broaden experience and understanding.

Process

Preplanning of survey site, risk assessments and permissions gained
On site risk assessments, calibrations and notice to authorities
Flight planning and survey methodology
Photographic and video survey of outcrops
Processing of data to create 3D point clouds, Orthomosaics and Digital Elevation Models
Creation of mesh and texture to create finished 3D Model for interpretation and exploring.
