HYDRODYNAMIC MODELING AS ONE OF THE DECISION METHODS FOR THE EFFICIENT DEVELOPMENT OF OIL FIELDS

Abstract

Oil production is a complex process that requires modern technologies, work experience and responsible personnel to implement cost-effective projects. Oil field exploitation processes stimulation or modeling is a method for researching exploitation objects on their analogs (models) in order to determine characteristics of available projected objects and make them distinct.
 The main objective of this research is to explore possibility and establishment of hydrodynamic stimulation results application effectiveness as a factor for decisions-making concerning oil or gas fields exploitation. The research, regarding optimization of oil field exploitation system, outlined the main directions and possibilities of oil extraction from depleted oil fields enhancement, and the hydrodynamic stimulation process as the main tool for solving such problems.
 The study of efficiency of oil and gas field development presupposed developing geological and technological model of a hypothetical deposit with technological indicators of a real Ukraine deposit. The hydrodynamic model was adapted for all wells according to actual data. All geological and technological measures, carried out in the sight, were also modelled. Field exploitation history was adapted. Oil field exploitation system was optimized by improving the reservoir pressure enhancement system in the real field. Different variants of field exploitation were considered. They include the conversion of the producing well in the injection well, whereas the well in the vaulted part is injected.
