Paradigm shift in hydrocarbon exploration and development strategies has increased utilization of seismic data many fold for reservoir characterization. Complicated and nonlinear relationship between seismic attributes and reservoir properties has been addressed recently using artificial neural network techniques for lithofaices classification and prediction of reservoir properties through unsu...

Abstract The overbalance pressure drilling technique is well common and practiced during the operations in petroleum field. This parameter very critical affects drilled formation characteristics, therefore, main objective of current study to evaluate impact that applied operation on rock elastic strength characteristics by employing integrated lab experimental work. Berea Buff sandstone type wa...

Abstract The role of natural fractures in future reservoir performance is prominent. fractured porous media composed an interconnected network and blocks the medium where occur various scales have a strong influence either when most flow concentrated them or they act as barriers. A general numerical model for discrete fracture networks (DFN) usually employed to handle observed wide variety prop...

Previous developments on zero-thickness interface elements for coupled HydroMechanics problems are briefly described, followed by some new geomechanical applications, particularly to hydraulic fracture in rock. The results are compared satisfactorily to approximate formulas and previously published numerical results. Once verified, the model is applied to new cases to show the capabilities of t...

Significant amounts of information are rapidly increasing in bulk as a consequence the rapid development unconventional tight reservoirs. The geomechanical and petrophysical characteristics wellbore rocks influence sweet non-sweet areas Using standard approaches, such data from cores commercial software, it is difficult costly to locate productive zones. Furthermore, apply these techniques well...

The present paper explores the combination of unmanned aerial vehicle (UAV) photogrammetry and three-dimensional geomechanical modeling in the investigation of instability processes of long sectors of coastal rocky cliffs. The need of a reliable and detailed reconstruction of the geometry of the cliff surfaces, beside the geomechanical characterization of the rock materials, could epresent a ve...

Abstract Viscosity-temperature behavior is important for the thermal recovery of bitumen: firstly, it a criterion evaluating evolution mobility with temperature, which affects oil production; and secondly, determines role bitumen in geomechanics sand reservoir. To quantitatively evaluate effect temperature on dynamic viscosity, some experimental modeling investigations were conducted. The visco...

flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. usually, a correct description of the lateral variations of reservoir is associated with uncertainties. from this point of view, the well data alone does not cover reservoir properties. because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...
