dc.description.abstractWith the design of experiments (DoE), this study analyses the influence of physical (capillary diameter and pressure drop) and chemical variables (salinity, polymer concentration, and molecular weight) on the mechanical degradation of partially hydrolyzed polyacrylamide-type polymer solutions (HPAM) used in enhanced oil recovery processes. Initially, with the help of a fractional factorial design (2k-p), the variables with the most significant influence on the polymer's mechanical degradation were found. The experimental results of the screening demonstrate that the factors that statistically influence the mechanical degradation are the molecular weight, the diameter of the capillary, and the pressure differential. Subsequently, a regression model was developed to estimate the degradation percentages of HPAM polymer solutions as a function of the significant factors influencing the mechanical degradation of polymer solutions. This model had a 97.85% fit for the predicted values under the experimental conditions. Likewise, through the optimization developed by the Box Behnken response surface methodology, it was determined that the pressure differential was the most influential factor. This variable was followed by the capillary diameter, where less than 50% degradation rates are obtained with low polymer molecular weight (6.5 MDa), pressure differentials less than 500 psi, and diameters of the capillary greater than 0.125 inches.eng
dc.description.abstractEste estudio evaluó mediante un diseño experimental la influencia de las variables físicas (diámetro de capilar y caída de presión) y químicas (salinidad, concentración de polímero y peso molecular), en la mecánica de soluciones poliméricas tipo poliacrilamidas parcialmente hidrolizadas (HPAM) utilizadas en procesos de recobro mejorado de crudo. Inicialmente, se realizó un diseño factorial fraccionado (2k-p), para determinar las variables con mayor influencia sobre la degradación mecánica del polímero. Los resultados experimentales del cribado indican que los factores que influyen estadísticamente en la degradación mecánica son el peso molecular, el diámetro del capilar y el diferencial de presión. Posteriormente, se desarrolló un modelo de regresión que permite estimar los porcentajes de degradación de soluciones poliméricas HPAM en función de los factores significativos con influencia en la degradación mecánica de las soluciones poliméricas. Este modelo tuvo un ajuste del 97.85% para los valores predichos bajo las condiciones experimentales. Asimismo, mediante la optimización desarrollada por la metodología de superficie de respuesta Box Behnken, se determinó que el diferencial de presión fue el factor más influyente, seguido del diámetro del capilar, donde las tasas de degradación inferiores al 50% se obtienen con polímero de bajo peso molecular (6,5 MDa), diferenciales de presión inferiores a 500 psi y capilares con diámetros superiores a 0,125 pulgadas.spa
