Lukoil has achieved first oil production at the Yu. Korchagin field in the Russian waters of the Caspian Sea.

For an investment of $1.17 billion (RUR 34.4 billion), field development at Yu. Korchagin includes an ice-resistant stationary platform (IRP-1) equipped with a drilling complex that has a loading capacity of 560 tons to drill wells 7,400 meters deep. IRP-1 was constructed at the Astrakhansky Korabel plant. Thirty subsea wells will be drilled to develop the field.

There is an additional ice-resistant stationary platform (IRP-2) for personnel accommodation. The living quarters can accommodate 105 people. Operation in the autonomous mode can reach 15 days. IRP-2 was constructed at ООО LUKOIL-Kaliningradmorneft’s plant.

Oil is transported from the production platform via a subsea pipeline measuring 58 kilometers long to a floating storage unit (FSU) with a deadweight of 28,000 tons. The FSU carries a crew of 25 men and is located outside of the Caspian ice zone.

Oil will then be transported from the area by shuttle tankers with deadweight of six to twelve thousand tons.

Drilling at Yu. Korchagin

The first well was drilled for oil extraction and the second one for extraction of associated gas that will be used for autonomous power supply to the facility. At the moment the third well is being drilled for water injection in order to maintain the formation pressure.

The Company implemented a unique for Russia engineering and technological solution, which is drilling horizontal wells with a length exceeding 5 kilometers. Due to a regular radial location of the wells, it is possible to simultaneously drill in all productive formations. Monitoring of the drilling process is also conducted from the shore via satellite channel in the on-line mode.

During an oil field construction Lukoil conducted satellite monitoring of the northern part of the Caspian Sea. The satellite data were received by the Company’s specialists in the quasi-real mode via the webservice Lukoil-Kosmosnimki. The monitoring revealed no evidence of oil spills within the boundaries of the Company’s license areas during the whole monitoring period.

Discovered by Lukoil in 2000, the Yu. Korchagin oil and natural gas field holds estimated 3P reserves of more than 270 million barrels of oil equivalent. The maximum expected output is 2.5 million tons of oil and 1 billion cubic meters of natural gas annually. The company expects to extract 343,000 tons of oil by the end of the year.
