TITLE:

Development of flow corridors along faults and fold hinges in carbonate units: implications for reservoir

KEY WORDS:

Fractures; Karst Conduits; Salitre Formation

PAGES: 31
BIG AREA: Ciências Exatas e da Terra
AREA: Geociências
SUMMARY:

The hypogenic caves developed in carbonate units have a significant structural control but most of their features are not detect by conventional methods due to their size below seismic resolution. This contribution focuses on the structural, petrographic and geometric characterization of karst conduits in Neoproterozoic carbonates of the Salitre Formation, central part of São Francisco Craton, Brazil. We address the influence of fractures and folds on the development of karst conduits through field and laboratory analysis and the application of Light Detection Ranging to characterize cave/conduit geometry. The preliminary results indicate that the process of karstification are intensified in fractures corridors developed along faults and fold hinges, which create fluid flow corridors in carbonate units and may change petrophysical reservoir properties
