Abstract

Summary

Many fractured reservoirs contain complex fractures network from micro fissures up to major faults. Each of the scales plays an important role in the fluid flow. In some cases fractures result from faulting, which means that the fracture network is closely related to the faults emplacement and should be modeled together. A part of existing methods is focused on a fine static representation of fractured network. Other part is focused on the precise calculation of dynamic phenomena. But all these approaches replace complex fracture patterns by its response on the larger scale and so an upscaling step is needed.

In our work we propose an alternative and integrated workflow of an explicit fracture network modeling using common numerical representation for both geological and dynamic models. The static model is constructed using a Multiple Point Statistics in order to represent complex patterns of fractures and faults interconnection. The dynamic behavior is simulated based on this realistic fracture reservoir representation. We illustrate our approach on a field case study where the reservoir model reproduces a multi-scale fracture network dynamic profile observed in the well tests. A good match to well test data is obtained by using an Experimental Design technique.
