Gazprom Neft has accomplished testing of new-generation seabed seismic stations (Flounder stations) for offshore exploration within the Sea of Okhotsk, a venture initially initiated in 2019. Development of this Russian-developed seismic-exploration tools is being undertaken with the involvement of the Ministry of Industry and Trade of the Russian Federation.
These “Flounder” seabed stations have been designed and launched by analysis and improvement company Aviation and Marine Electronics NPP, with the primary batch having efficiently accomplished laboratory testing. Marine Arctic Geological Expedition (JSC MAGE) and ROSGEO (Rosgeologica JSC) are scheduled to check the units beneath real-word circumstances at offshore license blocks belonging to Gazprom Neft later this 12 months. The earlier mannequin of those seabed stations — the CRAB — efficiently proved its capabilities throughout seismic exploration works on the Ayashsky license block within the Sea of Okhotsk in 2019.
The new seabed station is cylindrical in form, considerably bettering its ergonomics and making it straightforward to see even in poor visibility beneath difficult climate circumstances. The stations comprise new hydrophones and geophones, a compass and a built-in acoustic module — all of which improves high quality in knowledge assortment and processing, making it attainable to acquire a extra exact seismic map from work places.
The subsequent technology of seabed stations might be geared up with a mechanism permitting them to be lowered to the seabed and lifted again to the vessel mechanically somewhat than manually. This mechanism, which is anticipated to be developed by 2022, will make technicians’ work a lot simpler, in addition to growing pace in endeavor offshore seismic surveys.
Research and improvement firm Aviation and Marine Electronics NPP is a Russian firm chargeable for growing state contracts in pilot development works on the next authorities tasks: “Developing a Mobile Hardware/Software System for Marine Seismic Exploration and Monitoring in Offshore Transition Zones based mostly on New-Generation Four-Component Standalone Automatic Seabed Seismic Stations” and “Resource Testing of a Mobile Hardware/Software System for Marine Seismic Exploration in Offshore Transition Zones based mostly on Advanced Four-Component Standalone Seabed Seismic Stations.”
