Carbon dioxide (CO2) sequestration in subsurface reservoirs is important for limiting atmospheric CO2 concentrations. However, a complete physical picture able to predict the structure developing within the porous medium is lacking. We investigate theoretically reactive transport in the long-time evolution of carbon in the brine-rock environment. As CO2 is injected into a brine-rock environment...

In this work, a new dual modality monitoring technique is presented to demonstrate its interest investigate the salt precipitation dynamics induced by gas flow-through drying. It consists of imaging simultaneously core flood using both Neutron and X-ray beams. A method calibrate process two signals presented. takes advantage difference in attenuation between ionizing radiations quantify differe...

This paper presents simulations of the integral coefficients of performance of a heat pump system coupled with a vertical ground heat exchanger (GHE). The GHE is simulated using different assumptions concerning the heat transfer in the ground, heat exchange between the ground and the brine and vertical variation of the brine temperature. The differences in the predicted performance coefficients...

The time-dependent response of a surfactant hexagonal phase of a sodium dodecyl sulphate/pentanol/cyclohexane/brine system to stepped strain is investigated. The dynamics of the system is found to be governed by strain- and noise-induced yielding of the domains of the system. The effects of the applied strain magnitude and the ionic strength of the brine on the character of the transitions expe...

We present new experimental results relating to the growth and evolution of sea ice. These show, in particular, that brine initially remains trapped in the interstices of the sea ice, only draining into the underlying ocean once the depth of the sea-ice layer exceeds a critical value. A general theory for convection within mushy layers is applied to develop a hypothesis for when brine drainage ...

[1] Using 14 yearlong instrumented moorings deployed south of St. Lawrence Island, along with oceanographic drifters, we investigate the circulation over the central Bering shelf and the role of polynyas in forming and disseminating saline waters over the shelf. We focus also on evaluating the Gawarkiewicz and Chapman (1995) model of eddy production within coastal polynyas. Principal results in...

A model capable of predicting the minimum content of Aflatoxin M1 (AFM1) in Iranian while brine cheese has been developed using a chemometric approach to determine the optimum processing conditions. Renneting temperature, cut size, stirring time, press time, curd size and saturated brine pH were all regarded as process variables. Threedimensional response surface and contour plots were drawn. T...

The wetting behavior of oil on water (or brine) has important consequences for the transport properties of oil in watercontaining porous reservoirs, and consequently for oil recovery. The equilibrium wetting behavior of model oils composed of pure alkanes or alkane mixtures on brine is reviewed in this paper. Intermediate between the partial wetting state, in which oil lenses coexist on water w...

Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...

Raw material extraction from geothermal fluids often comprises concentrating and cooling steps, which increases the risk of silica scaling formation. However, existing removal strategies do not consider impact on raw extraction. In this study, applicability element-selectivity three techniques (seed-induced, lime caustic precipitation) were tested in batch experiments using synthetic natural fl...
