Abstract

The In Amenas in East Algeria is operated by a joint venture between Statoil, BP and Sonatrach. In this study we focus on the gas condensate production of the Cambrian and Ordovician reservoir Units of Tiguentourine field. A study to develop a methodology for a fracture model has been based on the available static data, i.e. borehole images, cores and seismic. The objectives are 1) to validate the structural image proposed by the geological and geophysical analysis, and 2) to characterize the hydrodynamical properties of this complex multi-scale fractured reservoir from dynamic data such as well test measurement. One well with both FMI interpretation and well test data have been analyzed. Firstly, a conventional well test interpretation was used. However, such a tool does not capture all the heterogeneities of the fracture system. Therefore, analyze was completed using a methodology based on fluid flow simulation within the actual fracture system. The applied FRACA model preserves the fracture distribution along the wellbore according the FMI interpretation. Despite the number of unknown parameters and the large uncertainties on the other characteristics, it was possible to match the well test signature fixing all the parameters with realistic values.
