SPE Horizontal Wells Survey Workshop in Russia
This workshop was dedicated to one of the most dynamic areas for development: logging in horizontal wells. Special attention was given to hydrodynamic studies, horizontal wells testing, production logging test (PLT), as well as new technologies and developments in this field.
Major Russian Oil&Gas companies participated in the event, such as Rosneft, Gazprom Neft, Lukoil, Novatek, Schlumberger etc.
All the advanced technologies and well logging techniques for complex horizontal wells, including array sensors, fiber-optic technology, Distributed Temperature Sensing (DTS), high-sensitivity spectral noise logging were showcased at the workshop.
Most of the presentations were specifically devoted to horizontal well logging. TGT technical presentation titled “Localization of gas, oil and water inflow zones in horizontal wells using high-sensitivity Spectral Noise Logging (SNL) and temperature modelling (Termosim) was delivered at the following session: “Horizontal wells: technologies, equipment, interpretation”.
1) Inflow profiling including identification of:
Drained / Undrained zones
Cross-flows behind casing
Water / gas breakthrough sources.
2) Well integrity surveys including:
Packer leak test
Frac sleeve operation survey.
3) Drilling Programme amendment:
Updating well path
Updating well design.
