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...

Fracture networks, apertures and flow patterns in carbonate rocks from the surface to reservoir depths: Fracture data acquisition and outcrop analogue modelling of outcropping carbonates in Bahia, Brazil

: In earlier stages of this project, we have characterized natural fracture patterns and fluid flow in outcropping Lower-Cretaceous carbonate pavements of the Jandaira Fm. in the Potiguar Basin, NE Brazil. We found that most fractures are formed during early burial, resulting mainly from NNE-SSW compression and partially from more recent NW-SE...
