Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus

This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ... En savoir plus

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they ... En savoir plus

The efficiency and environmental impact of oil production become a principal challenge of energy producing companies. The improvement of existing and development of novel methods are often feasible within either a “new” physical framework (from the viewpoint of oil reservoir ... En savoir plus

The increasing energy demand calls for advances in technology which translate into more accurate and complex simulations of physical problems. Understanding the rock damage is essential to understanding the geomechanics of hydrocarbon reservoirs. The fragile microstructure of some ... En savoir plus

This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... En savoir plus

Soil sedimentation and consolidation, whether they are naturally or anthropically driven processes, are closely interconnected. While theoretical models are available to separately describe the behaviour of either ‘fluid’ suspensions or ‘solid’ soil, no well-established unified theory ... En savoir plus

Increased concentrations of greenhouse gases in the atmosphere are known to be the main cause of global warming. Among the various decarbonisation strategies proposed, geological storage of CO2 is one of the most interesting options for reducing net carbon emissions to the atmosphere. ... En savoir plus

Transport of microorganisms through porous media governs many phenomena in bioremediation of environmental pollution problems and microbial enhanced oil recovery. The aim of this work is to investigate the effects of some transport parameters on breakthrough curves as well as on spatial ... En savoir plus

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... En savoir plus
