23th International Scientific and Practical Coiled Tubing, Hydraulic Fracturing and Well Intervention Conference

The conference will be held on November 17-18, 2022 in Moscow Organizers: the Russian Chapter of the Intervention & Coiled Tubing Association (ICoTA-Russia), Scientific and Practical Coiled Tubing Times Journal. Supported by the Ministry of Energy and the Ministry of Industry and Trade of the Russian Federation. Venue: Novotel Moscow City Hotel (Presnenskaya emb. 2, “Delovoy Tsentr” / “Vystavochnaya” metro station). Structure of the event: six technical sessions are planned for November. Topics of the sessions: • Coiled tubing technologies; • Latest hydraulic fracturing technologies (multistage fracturing in horizontal wells, fracturing plus hydraulic jet drilling, nitrogen fracturing, coiled tubing fracturing, large-volume fracturing, acid fracturing plus hydraulic fracturing, etc.); • Acid Treatments (including matrix acidizing); • Radial Drilling; • Up-to-date well logging techniques, including horizontal wells logging; conveyance of logging tools using coiled tubing and downhole tractors; • High-tech well intervention equipment; • Sidetracking; • Jet drilling; • Well service (fishing and milling operations, packer setting jobs, etc.); • New EOR technologies; • Cement squeeze operations; • Oilfield chemistry for high-tech oilfield service (hydraulic fracturing chemicals, EOR solutions, cement squeeze mixes, etc.).  Read more

Increasing the Well Coverage Zone – Micro-CT Application for Radial Jetting

A.V. Trifanov, A.S. Kichigin, E.N. Kozlov, Gazpromneft-Zapolyarye LLC; S.M. Simakov, Gazpromneft STC LLC; D.S. Leontiev, Tyumen Industrial University---------One of the most difficult stages of well completion is the secondary opening of productive layers. It is this stage that requires the most careful approach and the choice of the right technology both during construction and reconstruction, and during workover operations. As a rule, the contamination of the bottomhole zone during the primary opening of productive layers reaches several meters, which makes it almost impossible to provide hydraulically perfect connection of the well with the reservoir, despite the use of various modern technologies of secondary opening. The radial jetting technology is one of the innovative approach aimed at involving small oil deposits that remain away from the boundaries of the current development. Read more
