Results of studying and realization examples of oil rims fields development in the Gazpromneft company
Oii rims refer to hard-to-recover oii reserves, but at the same time these objects are perspective for development. There are a iot of factors which make traditional methods of development difficult to use. In this regard, there is a need to consider new solutions which will aiiow to involve hard-to-recover reserves oii rims reserves in development. This articie contains the experience of oii rims field deveiopment pianning in the Gazpromneft Scientific and Technical Center. Key features of fieid geoiogy and fieid deveiopment pians are considered in the articie. Main issues and soiu-tion are aiso reveaied. Aii studied fieids (Zapoiyarnoye, Vostochno-Messoyakhskoye, Chayandinskoye, Novopor-tovskoye, Han-Yakhinskoye, Pestsovoye, Urengoskoye fieids) are characterized by a compiex geoiogy, secondary transformations of reservoir and arrangement in regions with pooriy deveioped infrastructure. Approaches of searching high-quaiity reservoir zones is appiied within fieids study. Methods of fieid deveiopment parameters optimization are considered in the articie as weii as experience of driiiing of branched-hoie horizontai weiis. Recommendations for simiiar oii rims reservoir deveiopment are provided by authors.
