| Popis: | The purpose of this paper is to analyze the impact of the Brittleness index in hydraulic fracturing on shale gas formations worldwide, and thereby defi ne parameters to identify fraccable feasibly sweet spots in prospects shale plays. A literature review was made so as to gather the largest amount of petrophysical and mechanical data from shale gas formations from countries all over the world such as United States, China, Holland, Norway, Denmark and Sweden. Once available the data, different methods were used to calculate the brittleness index of each study case considering the effect of the mineralogical composition and elastic moduli (static and dynamic). The relation between the brittleness index at depth and the total organic carbon allowed to identify possible sweet spots within each prospect formation. Additionally, the analysis of brittleness index and mechanical behavior of those formations permitted to stablish which fracture fl uid should be used in case of a hydraulic fracturing stimulation at the sweet spot |
