Characterization of Hydraulic Rock Properties Using Probability of Induced Microseismicity

A006 CHARACTERIZATION OF HYDRAULIC ROCK PROPERTIES USING PROBABILITY OF INDUCED MICROSEISMICITY Abstract 1 In this paper we present a new approach for estimating the hydraulic parameters of rocks using an analysis of the spatial distribution of microseismic events induced by fluid injection. Such a monitoring of microseismicity can be used to characterize rocks in terms of hydraulic properties. Knowledge about these properties is important especially for an optimized developement of geothermal or hydrocarbon reservoirs. Our approach is based on the hypothesis that the propagation of triggering of injection-induced microseismic events can be described by a diffusive process of pore pressure
