Abstract
Description
En esta investigación, se evaluaron siete sustancias químicas seleccionadas de las familias de sales inorgánicas y colorantes usados normalmente en hidrología, como potenciales trazadores para un fracturamiento hidráulico, implementando métodos analíticos económicos para su detección y cuantificación y que se puedan realizarse insitu. A partir de los ensayos de adsorción, compatibilidad con el gel de fractura y los fluidos de formación, así como ensayos de desplazamiento en medio poroso, se identificaron tres sustancias que respondieron aceptablemente, tras ser sometidas a las condiciones físicas y químicas de un proceso de fractura hidráulica lo que las habilitaría para su uso como trazadores.

From adsorption tests, compatibility between the fracture gel and formation fl uids and core fl ooding tests, three substances responded acceptably, after being subjected to physical and chemical conditions of a hydraulic fracturing process which enable them to be used as tracers.
