Abstract

PJSC Rosneft Oil Company is implementing a series of initiatives related to development of large promising assets of West Siberia, in that number Tagulskoye oil-gas condensate field located within the Krasnoyarsk region. The field exhibits complex geology and reserves structure. Best global practices in the development of multilayer reservoirs provide for variations of successive extraction of reserves from the bottom up through drilling directional wells. With respect to the field under consideration, a stage-wise drilling approach is applied in an attempt to implement individual development systems based on horizontal wells for each pay zone. Drilling of multilateral wells with two or more horizontal holes has also been widely practiced. To enable production of high-viscosity (200 cPs) oil, which accounts for as many as 30% of initial in-place reserves, a targeted program for further study of hard-to-recover reserves areas has been developed. The article describes new unconventional solutions for the development of multilayer fields, characterized by complex and heterogeneous geological structure.

Key words:

field development strategy, multilateral well, discontinuous reservoir of continental genesis, project well stock, development phase, well pad, confident drilling zone.
