As the sea at the point of the well is 4.5 m deep, the well – with a target depth of 1650 m – is being drilled from the jack-up floating rig Astra, designed for shallow waters. The same structural tectonic zone features the Yury Korchagin, Valery Grayfer and Vladimir Filanovsky fields, discovered in 2000, 2001 and 2005 respectively.
The company has also begun to study the Khazri and Titonskaya features of a new block in the south of the same sea area within the East Sulaksky bank, and is currently drilling the second well to the target depth of 5200 m. The sea is 45 m deep at the point of the well. The well will deliver data on oil and gas content and explore for oil and gas deposits in terrigenous and carbonate sediments of the Jurassic-Cretaceous period.
As part of its drilling campaign for Caspian fields, Lukoil is constructing the sixth well at a riser block platform at the Yury Korchagin field. The length of the borehole of this horizontally directed producing well, equipped with a MultiNode intelligent completion system being used for the first time at Caspian projects, is 5164.79 m. The drilling is being performed from the jack-up floating rig Mercury. The well's daily target production rate of 348 t will stabilise the field's production.
