Abstract

Un método y un fluido para la perforacion y servicio de un pozo en una formacion subterránea que contiene reservorios de baja presion con zonas decirculacion perdida o agotada. Un método para disminuir la densidad del fluido circulado en un orificiode perforacion, disminuir la invasion de fluido dentrode las formaciones contactadas por los mismos, o disminuir el potencial de circulacion perdida de fluido, por medio del uso como fluido de un líquido acuosoque tiene disperso en el mismo unpolíme ro que aumenta la viscosidad de bajo régimen de corte del fluido en un grado tal que el índice de adelgazamiento decorte del fluido es de por lo menos 10, un surfactante, y afrones, en donde los afrones son generados preferiblemente por laturbulenci a y la caída de presiona medida que el fluido sale de la broca de perforacion en la vecindad de la formacion, teniendo el fluido una viscosidad de bajo régimen de corte es de por lomenos 10.000 centipoise. El fluido que tiene unaestabilidad térmica mejorada, tal como es indicado por la viscosidad de bajo régimen de corte del mismo,contiene adicionalmente una mezcla oligosacárida compuesta de pentosanos y/o hexosanos que contienen desde una hasta diez unidades combinadas deazucarseleccionadas d el grupo que consiste de arabinosa, mannosa, galactosa, glucosa, xilosa, celobiosa, y las mezclas de las mismas. Preferiblemente, la mezclaoligosacárida es la porcion soluble de lignocelulosa hidrolizada térmicamente.
