Naturally-fractured Reservoirs Assessment

A fractured reservoir is defined as a reservoir where naturally originated fractures are involved in fluid flow increasing reservoir permeability. In order to achieve the correct assessment of fractured reservoirs, natural fracture analysis is the key critical aspect to take care of. Nova´s experience has identified an integrated workflow that connects information from several scales, specially 3D seismic, wellbore data and cores where available.

TGeological description of fractured reservoirs has a final goal that consists in creating a 3D Discrete Fracture Network, which allows to identify the main characteristics of the fractured environment, leading to be the support for dynamic simulations.

Evaluation of the fracture connectivity leads to quantify wellbore deliverability, allowing multiple scenarios to be simulated and choosing the best case for future field development.
