Varyeganneftegaz: Increasing Production with Smart Well Completions
M.S.Kuvakina (Varyeganneftegaz JSC) Introduction Recently, Russian oil and gas companies have been actively implementing horizontal wells during field development. Such wells allow increasing the reservoir contact area with well, raising the production rates and performance, as well as increasing the oil recovery factor (OR) from the field as a whole. …
Return to Achimov: A Comparison of the Achimov and Neocomian Beds in the Noyabrskiy Region
Kirill Nikolayev Unclaimed Reserves The Achimov suite is the lowermost level of the Lower Cretaceous deposits overlying the Jurassic play. Its geological structure is complex, and that is why it took some time to start developing the Achimov. In some fields exploration activities to estimate the Achimov deposits and the …
Enhanced Oil Recovery Methods and ASP Technology
Yakov Volokitin, Mikhail Shuster, Volodimir Karpan, Salym Petroleum Development N.V. A steady growth in global energy demand requires more efficient production of traditional reserves. One way to address this challenge is to employ improved oil recovery (IOR) methods, which improve the existing recovery techniques (e.g. waterflooding) and apply new oil …
Laboratory and Field Tests for an ASP Flooding Project
Y.Е. Volokitin, M.Y. Shuster, V.М. Karpan, I.N. Koltsov (Salym Petroleum Development N.V.), А.G. Skripkin Introduction ASP projects involve the use of expensive chemicals, so Salym Petroleum Development (SPD) has taken a holistic approach to gradually de-risk the technology. The evolution of the ASP project at the West Salym field is …
Technology Roundtable: Fracturing
1. With the sanctions currently restricting Russia’s development of hard to recover reserves, has there been any accidental impact on fracking operations for conventional reservoirs? Weatherford: For conventional reservoirs, frac scopes have been reduced for all the contractors due to the plummeting oil prices. However, horizontal drilling and multi-stage fracturing …
