Title : The integration between global hydraulic elements approach (petro-typing) and petrography to identify the best intervals in the fluvial reservoir Sirte Basin Libya
Abstract:
The main objective of this study is to use Global Hydraulic Elements (GHE) Approach (Petro-typing or Rock Typing) to identify the best intervals during the hole of Fluvial sandstones reservoir sirte basin and integrating with Facies analysis. The most important emerging challenges of geoscientist and engineering is improved reservoir description, many reservoirs description program though detailed, have not always included description at the pore throat scale, reservoir description has many applications in the geology, petrophysics, reservoir engineering and production The Global Hydraulic Elements (GHE) has been developed to integrate geological and petroleum engineering data, Reservoir description is very important to understanding of the reservoir and it is generally hoped that more consideration of reservoir description may lead to less time spent history matching in reservoir modelling, in this study one well have been selected (X1, concession X sirte Basin). The Global Hydraulic Element (GHE) approach has applied to improve the reservoir description and identify petrophysical rock types for this reservoir. The methodology involves the analysis of routine core analysis porosity, permeability and calculation of Normalized porosity (Φ z), Reservoir Quality Index (RQI), Flow Zone Indicator (FZI) and Facies association has been performed to better define their relationship. The rock type distribution and facies associations as an aid to identifying the best reservoir intervals and better understanding and delineation of fluid flow. The results of this study show a good matching with this integration.
