Using an integrated approach to evaluate the quality of the reservoir and the potential of production is getting more and more important in petroleum geology.
This integrated approach was used to analyse the quality of an old Miocene reservoir in the Moesian Platform, Romania. While this paper goes through all the main components of an integrated study (seismic, petrophysics, reservoir engineering), the main focus was on well data. This research focused on modelling the structure using mainly well data. The reservoir is associated with an alluvial cone structure and a canal system NNW-SSE, with the lithological traps in the southern part [1]. The reservoir pressure and the behaviour during production indicates a gas expansion is the main displacement mechanism, alongside a low influx of water. The results of this paper show that the performance of the reservoir is influenced not only by the available energy (the elastic gas expansion and a low influx of water), but also by the spatial distribution of different facieses in relation to the well locations. Gas production started in 1962 and continues to this day. However, the Miocene reservoir was chosen for gas storage (UGS-Underground Gas Storage) due to his relatively large thickness, good porosity and large surface area [2]. The purpose of a reservoir characterisation is to incorporate existing data from geological, petrophysics, geophysics and reservoir engineering, so that the results obtained by the multidisciplinary team can be used to create a reservoir model which will improve economic results. The methodology and the results for each phase are summarized in the following sections: seismic, petrophysics and reservoir engineering. |
