The first Russian offshore platform, Piltun-A (PA-A) — known as “Molikpaq” after the Inuit word for “big wave” — has an average production rate of 90,000 barrels of oil and 1.7 million cubic metres of gas per day. It started year-round production in December 2008. There are 13 oil production wells, four water injection wells, one gas reinjection well and one waste disposal well on the platform.
At the Lunskoye-A platform, gas is produced from the largest diameter wells ever drilled in Russia. Two new gas production wells were completed in 2010, which brought the total number of wells to seven. The Lun-A gas production rate is up to 51 million cubic metres per day and condensate about 8,000 cubic metres per day.
Piltun-Astokhskoye-B (PA-B) is the biggest offshore platform in the Sakhalin-2 project. Two oil production wells and three water injection wells were drilled in 2010, bringing the number of oil wells at the platform to eight. Two additional water injection wells were drilled in 2011. The platform production capacity per day: oil approximately 70,000 barrels and associated gas 2.8 million cubic metres.
A 300-kilometre undersea pipeline network links the three platforms to an onshore processing facility. From there an onshore system of 1,600 kilometres of pipelines takes the oil and gas to an LNG (liquefied natural gas) plant and oil export terminal, both at the Prigorodnoye complex at Aniva Bay in the south of the island.
