Abstract

PRODUCCION DE UNA SOLUCION DE BIOPOLIMERO DE XANTOMONAS DE ALTA FILTRABILIDAD. CONSISTENTE EN MEZCLAR UN CALDO DE FERMENTACION DE BIOPOLIMERO DE XANTOMONAS A PROPORCIONES DE 3 A 18% Y 0,0128 A 0,0512% RESPECTIVAMENTE A UN PH SUPERIOR A 5. DESPUES DE UNAS TRES HORAS COMO MINIMO, SE AGREGA A DICHA MEZCLA DE 300 A 5.000 PPM. DE FORMALDEHIDO Y SE DILUYE POR CIZALLAMIENTO PARA PRODUCIR UNA REDUCCION DE LA VISCOSIDAD EFECTIVA DEL BIOPOLIMERO DE 5 A 30%. DE UTILIDAD EN LA RECUPERACION DE PETROLEO CRUDO DE UNA FORMACION SUBTERRANEA PETROLIFERA POR INYECCION DE LA COMPOSICION DILUIDA EN LA FORMACION.
