... evidences urge for (he development of an improved way to analyze the stability of oil wells, due to the increase in challenges resulting from considering more difficult reservoirs. This paper presents an innovative way to analyze wellbore stability using energy concepts. The rock mechanics aspects...

... Abstract This paper dealt with the numerical modelling with the LAGAMINE finite element code of the large strain elastoplastic deformation of a basin taking into account the hydromechanical coupling. One describes the rock mechanics model, the flow model, and the coupling between them. Volume...

... ABSTRACT Basic concepts of fracture mechanics are discussed to analyze their applicability in modeling fracture initiation and propagation during hydraulic fracturing and waterflooding. Recent advances in modeling fracture initiation and quasi-equilibrium growth are reviewed. Special attention...

... Abstract The Northern Adriatic basin contains a great number of developed fields at depth ranging between 1000 and 4000 meters, and a comprehensive geophysical, petrophysical and mechanical characterization of these weakly consolidated formations was carried out. For 15 wells cored in the pay...

... the salient features of experimental work on the fluid/shale interaction and use a finite-element scheme to numerically calculate the stress and strain distribution around a wellbore when interactions occur. We show that these effects promote tensile failure of the wellbore wall. interaction mechanics...

... Abstract This paper reviews field experience of produced water re-injection. Recent improvements in understanding the processes which control reinjection are described, demonstrating the key role of rock mechanics in enabling successful reinjection of large volumes of dirty water via waterflood...
