This phenomenon, known as adsorption 18, can be estimated by analytical models and depends on several factors like the type of rock, degree of hydrolysis and polymer concentration, reservoir temperature, salinity of formation water, among other aspects. This paper shows the results of 144 statics tests where salinity (NaCl and CaCl 2 ) and polymer concentration were taken as the parameters to be changed in order to determine which analytical model is the most accurate for the prediction of experimental results. The abnormal adsorption tendency with NaCl, indicates that the grater salinity value, the lesser adsorption value concentrations. This is mainly due to the response of the kaolinite substrate to flocculation. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49662789008 https://www.redalyc.org/journal/496/49662789008/ https://www.redalyc.org/journal/496/49662789008/html/ https://www.redalyc.org/journal/496/49662789008/49662789008.epub https://www.redalyc.org/journal/496/49662789008/movil 10.15446/dyna.v86n210.74361 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.210 Vol.86 |
