This book explains different phenomena that occur in Naturally Fractured Reservoirs (NFRs) of carbonate rocks neighboring a salt structure and how it affects well drilling. Prediction of carbonate pore pressure is difficult; therefore, a new set of pore pressure equations for carbonates were developed, accounting for overpressure and depleted conditions. A detailed description of a fully coupled model is shown in order to discuss geomechanics and the coupling of fluid flow in porous media and to achieve a better representation of the mechanics involved in the exploitation of NFRs. Additionally, results of a new model of geomechanics in vuggy carbonate reservoirs are presented. This book also displays a wide discussion, analysis, and numerical implementation of six different salt rheology models. Furthermore, the most representative rheology salt models were studied aside with the fully coupled model of geomechanics and fluid flow in porous media. Finally, it presents an answer to areal case of a well drilled near a salt diapir where anomalous pore pressure was found.
