Full Field Characterization Discipline for Modeling of Gas Condensate Reservoirs

Full field characterization is the cornerstone of asset management in development of green fields which can result in operational and financial success of the project plan. The more accurate characterization of the field can reduce the investment uncertainties and lead to a successful risk management. This can be achieved by means of an integrated and multi-disciplinary teamwork through implementation of organizational practices and workflows. To develop an integrated reservoir model geological, geophysical, petrophysical, and engineering data must collaborate in one environment such that the most realistic geologic model can be obtained. So the proper economic asset valuation can be based on this characterization method which can be employed in field development planning.

Gas condensate fields are different from other fields mainly in phase behavior of reservoir hydrocarbon fluid. The retrograde phenomenon in these reservoirs makes pressure control of wells an important key factor in designing of production scenario. Herein it has been considered to show the step by step procedure for characterizing a giant gas condensate field in order to find the optimum plan for management of the reservoir. To develop a reliable model PVT data, core data, micro-resistivity logging, and geology stratigraphy have been studied in an integrated discipline.
