Many of the mathematical complexities encountered with time-dependent coupled processes in rock/fluid interaction have been overcome. The coupled phenomena associated with the rock matrix deformation, fluid flow, temperature gradients, and chemical activity have been modeled in an analytical form. And the various analytical solutions related to rock testing and wellbore stability simulations have been implemented in two industry-supported software tools: PCORE-3D and PBORE-3D. On the one hand, PCORE-3D is intended for simulating and analyzing laboratory rock testing. On the other hand, PBORE-3D is targeted at predicting and designing wellbore stability during drilling.Both packages are modeled within the frameworks of the time-dependent coupled theories of poromechanics as well as the classical theory of solid mechanics. The design engineer, thus, is capable of comparing solutions of the specific problems, within the realm of these theories. In this study, the solutions to the subject problems are explained with illustrative emphasis on laboratory and field cases; the mechanical interpretation of the output is cognitively elaborated; and both software tools are fundamentally described in details with their respective 3-D monitoring capabilities illustrated.IntroductionBiot's theory of poroelasticity1 represents an accurate and proven prediction tool of coupled time-dependent phenomena induced by stress perturbations in the geomechanical domain. It has already been recognized the importance of this coupling process to our understanding of borehole stability problems and design and analysis of laboratory testing procedures. Stability of (vertical, inclined, or horizontal) boreholes in deep drilling operations remains one of the major problems in the oil and gas industry. Meanwhile, solid and hollow reservoir rock samples are routinely tested to gain insights into the mechanical properties and to assess the stability of cylindrical openings. PBORE-3D and PCORE-3D are two packages that are intended to perform analyses of stresses/pore pressure and help design and assess drilling operations and setup experimental runs.PCORE-3D is a tool that presents time-dependent analytical solutions to the process of simulating poro-mechanical rock testing in a lab. In short, it is a virtual rock testing and rock deformation simulator. The software is aimed (among others) at better tuning testing frames, saving on the total number of required cores, optimizing the calibration and interpretation of testing results, improving the measurement of poromechanical parameters, extending the range of mea-surable parameters, modeling of in-situ stress determination, and simulating hollow and full cylindrical geomaterial testing. The tool will also be greatly valued in the study of reservoir compaction, wellbore stability, breakouts, and sanding phenomena.PBORE-3D, on the other hand, is designed to simulate the three-dimensional time-dependent wellbore stability while drilling. Mud weight windows are calculated as time progresses, thus illustrating the true nature of the phenomena of diffusion, temperature gradient, and chemical activities between the mud and the rock formation.In this paper, an overview of both tools is presented and a validation of their use is described and illustrated. The applicability of PCORE-3D is featured in a number of sample runs that are detailed at two levels: mechanical and experimental. The applicability of PBORE-3D, on the other hand, is demonstrated through its use in a borehole stability analysis for a field case. The analytical response solutions will not be explicitly presented herein. Rather, this paper focuses on both products and their use value to the oil/gas industry.Poromechanics Constitutive Relations:The time-dependent coupled diffusion-deformation effects including the temperature gradients and the chemical activity are best modeled within the general theory of poromechanics.
