Rosneft has spudded the Maria-1 exploration well offshore in the Black Sea. Forecasted oil in place for Zapadno-Chernomorskaya licence area is estimated to exceed 570 million tons.
Drilling preparations included acquisition of more than 4,000 kilometers of 2D seismic and over 3,000 square kilometers of 3D seismic data together with integrated geotechnical surveys.
Drilling the first exploration well in the Zapadno-Chernomorskaya licence area is part of joint activities with Eni – Rosneft strategic partner.
It is a unique project. Designed well depth is 6,126 meters with the water depth at the drilling site exceeding 2,000 meters.
The well is drilled by Scarabeo 9 semisubmersible rig operated by Saipem. Rig mobilization was an extremely complex yet successfully delivered engineering and transportation operation. On September 2017 the rig left the port of Las-Palmas, passed the Bosphorus strait and arrived to the Romanian port of Constanta a month later. Total distance en route exceeded 3 thousand nautical miles.
The rig is equipped with a high-precision dynamic positioning system which ensures constant location of the platform right over the wellhead.
The rig is 115 meters high with the deck 80 meters wide. Scarabeo 9 has the deadweight of 31 thousand tons and is capable of drilling up to the depth of 15,000 meters.
The rig meets all the technical requirements of the Project and rigorous environmental standards. To prevent any technical and environmental risks the rig has a BOP system with seven blow-out preventers. The sea environment condition will be monitored on a permanent basis including satellite observations. Besides, well construction will be controlled by two subsea remotely-operated devices on around the clock basis. (Source: Rosneft)
