Previously, Istiglal Rig also drilled the fourth pre-drilling well on Shahdaniz field under the project of development Stage 1. The well was drilled from the existing depth, drilling slab installed at the water depth of 101 meters in a point close to the crest of structure. The vertical space of the well head was 1,44 km. The depth of the well reached 6,189 meters.
The drilling of the well was sanctioned by the parties to Shah Deniz project in 2004 in order to ensure production of 3bln c m of additional gas for Azerbaijan during the first three years after gas production was launched at the end of 2006.
