Abstract

Summary

Oil and gas industry is currently facing a serious challenge - general deterioration of reserves structure together with natural depth increase of developed deposits, and a significant reduction of reservoir pressure at fields developed at eighties. All of these reasons show the necessity of use of every available knowledge and technology. In recent years, LUKOIL is rapidly developing a geomechanical modeling, especially in well planning: pore pressure prediction, wellbore stability while drilling, etc. Branch of LLC “LUKOIL-Engineering” “KogalymNIPIneft” was actively involved in the development of geomechanical modeling in Western Siberia in 2014. During the period of 2015–2016, specialists of drilling department made constructional geomechanical models of wellbore stability in the following fields of LLC “LUKOIL-Western Siberia”: Vateganskoe, Povkhovskoye and Pyakyakhinskoye fields. The results obtained were used in the analysis of complications and the development of the prevention strategy, during drilling of explorational, directional and horizontal wells and sidetracks.
