Paper Number: SPE-18589-MS
.... In this paper, we present the rheological properties of various borate crosslinked fluids employing a new procedure which simulates field pumping conditions, i.e. crosslinking the fluid on the fly, and fluid flow down tubing or casing and in the fracture. The effects of fluid pH, gelling agent concentration...

... in both the brine and oil phases. Thus, the concentrations of CO 2 species in both the oil and the brine will decrease. At the same time, the pH value of the remaining brine will increase with decreasing pressure as this gas flash process is proceeding. The amount of CO 2 remaining within the brine...

... In Figure 5 are illustrated the effect of NTA variations when calcium, pH, and ATMP are constant. Increasing NTA (increasing the concentration of calcium-NTA chelate) increases time to precipitation. From the part each of these components plays in the overall reaction, these effects...
