Simulation of naturally fractured reservoirs is a technically complex problem, both in terms of the characterisation and modelling of flow. This is due to the presence of irregular and highly heterogeneous flowing features on a range of scales.

 

Successful exploitation of these reservoirs benefits from assessing the impact of such heterogeneities on recovery processes. The main challenges for the reservoir engineer are in interpreting data, predicting near-well flow behaviour and parameterising regional-scale continuum models. Serco Assurance has developed systematic techniques for addressing each of these issues based around the NAPSAC software.
