The oil and gas firm, Lukoil, has started drilling an exploration well at the Shirotno-Rakushechnaya prospect structure near the VI Grayfer field in the northern part of the Caspian Sea.

According to the Russian firm, the Shirotno-Rakushechnaya exploration well is contained in 4.5m water depth and will be drilled to a target depth of 1,650m using Astra rig, which is said to be specially designed for drilling in shallow waters.

The oil and gas giant also disclosed that the structural tectonic zone of the well is identical to that at the Yury Korchagin, Valery Grayfer, and Vladimir Filanovsky fields. These fields were discovered in 2000, 2001, and 2005 respectively.

“The company has also begun to study 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 5,200m.”, a press statement from the firm says.

“The sea is 45m deep at the point of well. Drilled at Khazri feature from jack-up floating rig Neptune, 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.”

Under its drilling programme for Caspian fields, the Russian firm is constructing the sixth well at the riser block platform at the Yury Korchagin field.

Lukoil noted that this well is being executed by the Mercury jack-up floating rig.
