The viability of the exploration of an oil field is associated with the productive characteristics of the formation, guaranteed by means of the development and application of techniques capable of increasing the productivity and the economy of the oil fields. The currently most used stimulation technique is hydraulic fracturing, by which one of the main stages is the injection of a granular material called proppant to keep the fracture open and enhance fracture permeability. This technique presents as a drawback the phenomenon known as proppant flowback. The proppant is carried to the inside of the well causing many problems which can lead to production interruption. Some empirical and theoretical models for its prediction have been developed, however the mechanisms that govern it are still not clearly explained. Parameters that are related to proppant flowback are fracture width, closure pressure, drag force and proppant characteristics. Proppant flowback prediction is not included in today s procedures of the hydraulic fracturing project. In the present work a computational tool for proppant stability analysis was developed based on empirical and theoretical prediction models. This tool has an object oriented architecture written in Java language. The influence of the introduction of restrictions to prevent proppant production in the hydraulic fracture design procedure was also investigated. In this way, it is aimed to obtain hydraulic fracturing projects by which proppant flowback is prevented in field situations assuring well productivity and extending its activity period.
