Experience in the Implementation and Research of Multilateral Horizontal Wells in the Vankor Cluster Field

Abstract

The paper presents an assessment of multilateral horizontal wells performance, which is relevant for the conditions of the Vankor Cluster of fields in view of the beginning of active development phase to involve low-productive reservoirs of Nizhnekhetskaya Formation into development. With the development of the asset reserves, a natural decrease in input productivity is observed in the zones with poorer properties. This circumstance requires the introduction of new promising technologies, such as multistage hydraulic fracturing in horizontal wells (Hz wells with MHF) and drilling multilateral horizontal wells (MHz) which have already proven themselves on the positive side under similar conditions in the fields of West and East Siberia.
