Description
Una nueva metodología basada en el método del ácido dinitrosalicílico – DNS– fue desarrollada y aplicada para cuantificar de manera directa la eficiencia de los rompedores de fluidos de fractura base agua. Rompedores de diferentes compañías de servicios y una enzima comercial específica para la goma guar y sus derivados, usada por primera vez como rompedor, fueron evaluados. Los rompedores fueron ensayados a 70 y 100°C y a las concentraciones recomendadas por las empresas de servicios. La enzima fue evaluada a 100°C y con diferentes concentraciones de metanol en solución.
La nueva metodología desarrollada demostró ser fácil de aplicar, eficaz y económica para determinar la capacidad de los rompedores para degradar el polímero de los fluidos de fractura base agua.
A new methodology based on dinitro salicilyc acid –DNS- was developed and applied to quantify directly the breakers action on polymers used in the water-based fracturing fluids. Breakers from different services companies were tested. furthermore, a specific enzyme for guar gum and its derivates was tested as a breaker by first time. all the breakers were tested at 70 and 100 °C. The breakers concentrations were suggested by the services companies. The enzyme was tested at 100 °C and adding different methanol concentrations. It was demonstrated that the new methodology uses is easy, fast and non expensive way to measure the breakers ability to degradate the polymer in the water-based fracturing fluid.
