TL;DR: In this paper, chemical and isotopic data for deep seated calcium chloride brine from the Miramar Con gold mine, Yellowknife NWT, strongly suggest that the brine salinity is of marine origin.

TL;DR: In this article, a direct contact membrane distillation (DCMD)-based desalination process is explored in the range of 80-130°C for brines containing 10,000-ppm sodium chloride with porous flat sheet polytetrafluoroethylene (PTFE) membranes.

TL;DR: In this article, an experimental and modeling study of two fundamental properties in high pressure CO2-NaCl brine equilibrium, i.e., CO2 solubility in NaCl brines and CO2 saturated NaCl density, is presented.

TL;DR: A novel method to synthesize nesquehonite, MgCO(3) x 3H(2)O, via reaction of a flux of CO(2), with Mg chloride solution at 20+/-2 degrees C, which is a promising complementary solution to other methods of CO (2) sequestration.

TL;DR: In this paper, the mass transfer of CO2 into a reservoir brine sample is studied experimentally at high pressures and elevated temperatures, and it is found that the density of the brine with dissolved CO2 increases linearly with CO2 concentration.
Abstract: In this paper, the mass transfer of CO2 into a reservoir brine sample is studied experimentally at high pressures and elevated temperatures. The equilibrium concentration of CO2 in the reservoir brine and the density of CO2-saturated brine are measured by saturating the brine with CO2. The mass-transfer rate of CO2 into the brine is determined by monitoring the pressure decay inside a closed, visual, high-pressure PVT cell. It is found that the density of the brine with dissolved CO2 increases linearly with CO2 concentration. As CO2 gradually dissolves into the brine by molecular diffusion, a concentration-induced density gradient is generated near the CO2−brine interface. Under the influence of gravity, this concentration-induced density gradient causes natural convection, which accelerates the mass-transfer rate of CO2 into the brine. The modified diffusion equation with an effective diffusivity is applied to model the mass-transfer process. It is found that the determined effective diffusivities of CO2...
