7 Persistent scatterers synthetic aperture radar interferometry (PSI) analysis is viewed as a 8 promising monitoring technique for multiyear detection of ground surface displacements 9 during long term CO2 injection into deep aquifers (of the order of 25 to 50 years). 10 This technique was successfully utilized at the CO2 storage site of In-Salah (Algeria). 11 Nevertheless, this success may not...

Direct injection of liquid CO2 into the ocean has been proposed as one method to reduce the emission levels of CO2 into the atmosphere. When liquid CO2 is injected (normally as droplets) at ocean depths >500 m, a solid interfacial region between the CO2 and the water is observed to form. This region consists of hydrate clathrates and hinders the rate of dissolution of CO2. It is, therefore, exp...

climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...

CO2 flooding process as a common enhanced oil recovery method may suffer from interface instability due to fingering and gravity override, therefore, in this study a method to improve the performance of CO2 flooding through an integrated ultraosund-CO2 flooding process is presented. Ultrasonic waves can deliver energy from a generator to oil and affect its properties such as internal energy and...

PURPOSE The purpose of this study was to assess the accuracy of carbon dioxide compared to iodinated contrast material for determining inferior vena cava (IVC) diameter prior to filter placement, and to assess the safety of CO2 when used for this purpose. PATIENTS AND METHODS Consecutive patients undergoing inferior vena cavography prior to filter placement were prospectively evaluated with u...

We performed an experimental and numerical investigation of a convective buoyancy-driven instability that arises during the injection denser miscible fluid into less dense one in rectilinear geometry. visualized using shadowgraph technique, we obtained quantitative information micro-Particle Image Velocimetry. Numerical simulations provided further insights three-dimensional (3D) velocity field...

The paper investigates the linear growth of mixing zone, in a pessimistic scenario, during polymer slug injection into water reservoir. velocities front and boundaries zone are numerically analytically studied as key parameters characterizing miscible displacement. Using two different numerical methods (finite volumes finite elements), impact size, reservoir dimensions, Peclet number, viscosity...
