Abstract
A method of analysing the dynamic behaviour of fracture networks in a seismic volume is provided. The method includes providing a plurality of seismic time lapse vintages of the same geological volume; identifying and parameterising fractures within fracture networks of each vintage; determining one or more distributions of fracture parameters for the fracture networks of each vintage; and identifying changes to the fracture networks by comparing corresponding distributions across the vintages.

A method of analysing the dynamic behaviour of fracture networks in a seismic volume, comprising the steps of:
- (a) providing a plurality of seismic time lapse vintages of the same geological volume;
- (b) identifying and parameterising fractures within fracture networks of each vintage;
- (c) determining one or more distributions of fracture parameters for the fracture networks of each vintage;
- and
- (d) identifying changes to the fracture networks by comparing corresponding distributions across the vintages.
