Method and system for estimating an effective leak-off coefficient of natural fractures in a naturally fractured reservoir

Abstract

A method for obtaining an effective leak-off coefficient of natural fractures in a naturally fractured reservoir is described. In an embodiment, the method comprises: (i) receiving empirical data associated with a parameter characterizing an interaction between the natural fractures and hydraulic fractures formed by hydraulic fracturing the naturally fractured reservoir; (ii) iteratively performing simulation for hydraulic fracturing the naturally fractured reservoir by varying a leak-off coefficient of the natural fractures to obtain an optimized simulated data, the optimized simulated data matching the empirical data associated with the parameter; and (iii) estimating the effective leak-off coefficient, the effective leak-off coefficient being a value of the leak-off coefficient used in the simulation for generating the optimized simulated data.
