Results of studying and realization examples of oil rims fields development in the Gazpromneft company

Abstract

Oil rims refer to hard-to-recover oil reserves, but at the same time these objects are perspective for development. There are a lot of factors which make traditional methods of development difficult to use. In this regard, there is a need to consider new solutions which will allow to involve hard-to-recover reserves oil rims reserves in development. This article contains the experience of oil rims field development planning in the Gazpromneft Scientific and Technical Center. Key features of field geology and field development plans are considered in the article. Main issues and solution are also revealed. All studied fields (Zapolyarnoye, Vostochno-Messoyakhskoye, Chayandinskoye, Novoportovskoye, Han-Yakhinskoye, Pestsovoye, Urengoskoye fields) are characterized by a complex geology, secondary transformations of reservoir and arrangement in regions with poorly developed infrastructure. Approaches of searching high-quality reservoir zones is applied within fields study. Methods of field development parameters optimization are considered in the article as well as experience of drilling of branched-hole horizontal wells. Recommendations for similar oil rims reservoir development are provided by authors.
