Abstract

An experimental methodology was designed for recreate the CaCO3 continuous deposition in a porous media, displacing synthetic brines made of a typical composition of Colombian Field’s formation water, in known permeability Berea Plugs at different temperatures and different flow rates. The factorial experimental design used allowed to correlate thermodynamic parameters (represented by concentration of Ca++ and temperature) and hydrodynamic (represented by injection rate) during the entire displacement tests of brine in rock, in which the permeability reduction was thoroughly monitored, reaching values up to 90%. The proposed correlation in this study was developed with the aid of statistic software, which allows predicting the permeability reduction percentage due to CaCO3 scales, with an 85% data adjustment. This correlation was validated through another set of experimental tests, using several flow rates (1-3 cm3 / min), several temperatures (150-250 F) and different concentration of Ca++ ion in the synthetic brines (250-750 ppm).
