... react with other ions in solution and with the mineral in place to give rise to the precipitation and dissolution of various minerals. The reaction rate is very slow and it takes hundreds of years to obtain a reasonable amount of precipitation. A typical reaction is the precipitation and dissolution...

...-equilibrium rate equations that simulated the delay in solvent reaching its equilibrium concentration as it dissolves or exsolves in the oil in response to changes in the pressure and/or gas phase composition. Dissolution of CH4, C3H8, and CO2 in oil and CO2 in water were considered, as was exsolution of CH4...

... 800 meters, dissolution of CO2 into brine causes density of the mixture to increase. If the corresponding Rayleigh number of the porous medium is enough to initiate convection currents, the rate of dissolution will increase. Early time dissolution of CO2 in brine is mainly dominated by molecular...

.... This was observed under conditions of warm VAPEX, where the butane condensed inside the glass micromodel. In comparison, bitumen dissolution was not observed (due to the opacity of the live oil) in the normal mode of VAPEX operation when solvent vapour diffuses directly into the bitumen (James, L.A. and Chatzis, I...

... Abstract Stimulation of carbonate formations by acid dissolution of the rock has been an efficient and successful method of bimproving production in oil and gas wells. Hydrochloric acid is the normal fluid of choice. However, in high temperature applications corrosion issues limit usage...

... are performed to examine the effect of various deposition model parameters. A preliminary investigation of the inclusion of geochemistry in a CO 2 EOR process is conducted. Simulation runs show that the injection of CO 2 initially induces Calcite dissolution. However, if CO 2 is left in the reservoir after...
