摘要: The Eocene El Garia Formation in the offshore Hasdrubal Field was originally a nummulitic limestone which subsequent burial dolomitization has significantly enhanced permeability. Identification of reservoir9s petrophysical property distributions requires knowledge spatial extent its dolomitization, turn requiring understanding processes that caused dolomitization. Some this can be derived from measurements but others need to simulated. In study, former are used as guides and we focus on latter, evaluating character dolomitizing fluid9s movement temperature patterns by using basin modelling develop heat-flux simulations represent time Basin reconstructs region9s geology at while recreate appropriate conductive convective heat mass transport through these systems. Potential key drivers rock fault-zone permeability, position shape any salt domes. results suggest dome is dominant control, localizing systems also use convenient faults so hotter upwelling fluids pass reservoir instrumental development
