The Pechora LNG development in the Nenets autonomous region of Siberia could produce up to 8 million tonnes per annum of LNG at a capital cost of up to $12 billion.A pre-investment study by Gazprom’s design institute Giprospetsgaz found that gas production in the feedstock fields for the proposed Russian export project will total 4.5 billion to 13.4 cubic metres per annum. LNG production could as a result total 2.6 million to 8 million tpa, according to Interfax.Capital expenditure is estimated at anywhere between $4.5 billion and $12 billion depending on the technical concept chosen for the plant and production volumes.Developer Pechora LNG, formerly known as CH-Oil&Gaz, is considering two types of liquefaction plant.The first involves construction of an onshore-based facility and port infrastructure at Cape Bolshoy Rumianichny. The second would see floating LNG technology sited at Gornostalya Bay. Pechora LNG has been in talks with Gazprom over possible co-operation on development of feedstock gas fields.Giprospetsgaz considered and analysed a total of 12 options for implementing Pechora LNG. The pre-investment study will be submitted to Gazprom’s upstream department for evaluation.
