Linking natural fractures to karst cave development: A case study combining drone imagery, a natural cave network and numerical modelling

In carbonate rocks, channelized fluid flow through fracture conduits can result in the development of large and connected karst networks. These cavity systems have been found in multiple hydrocarbon and geothermal reservoirs, and are often associated with high-permeability zones, but also pose significant challenges in drilling and reservoir...

3D Outcrop Study of Hypogene Karst Caves of Brazil using LIDAR and Drone Imagery

The fieldwork was focussed on quantification of the morphological features of hypogenic karst caves in Brazil using 3D LIDAR (Light Detection and Ranging) and Drone Imagery. The fieldwork was conducted along with several partners as part of the Porocarste 3D project which is a consortium of three Brazilian universities (UFRN, UFRJ and UnB) and...
