Title: TIME-DEPENDENT SPATIAL DISTRIBUTION OF PROPPANT EFFECTS IN A DISCRETE FRACTURE NETWORK
Abstract:
A hydraulic fracturing flow simulation method includes identifying a discrete fracture network that partitions a reservoir into porous rock blocks. The method further includes determining a current network state that includes flow parameter values at discrete points arranged one-dimensionally along the fractures in said network. The method further includes constructing a set of linear equations for deriving a subsequent network state from the current state. The method further includes repeatedly solving the set of linear equations to obtain a sequence of subsequent network states, the sequence embodying a time-dependent spatial distribution of at least one flow parameter, said flow parameter comprising a proppant volume fraction. The method further includes displaying the time-dependent spatial distribution.
