Characterizing and Modelling Fractures and Karst in Carbonate Units - The Porocarste Project

We investigated the Quaternary epigenic karst system in the Jandaíra Formation, a Turonian–Campanian carbonate platform in the Potiguar basin, northeastern Brazil. We concentrated our investigation in the vadose zone of the present-day karst, but also used borehole data. The leaching zones are preferentially concentrated along pre-solution...

Outcropping analogs and multiscale fracture patterns in the Jandaíra formation

Outcropping analogs can provide key information on the 3D organization of fracture networks affecting carbonate reservoirs. Such information, however, needs to be integrated in a consistent work flow which includes i) 3D geometric model of the reservoir architecture, ii) mechanic modeling to determine areas of fracturing, iii) characterization...

Dissolution along fracture systems in Turonian-Campanian carbonates in Brazil

Hydrothermal activity along a strike-slip fault zone and host units in the São Francisco Craton, Brazil – Implications for fluid flow in sedimentary basins

This study combines multiscale analyses of geological, fault, fracture, and stable isotope data to investigate strike-slip deformation and channeling of hydrothermal fluids along the Cafarnaum fault and calcite veins at different distances from the fault, which is a structure in the São Francisco Craton, northeastern Brazil. Meteoric fluids...
