The Zapolyarnoye Oil and Gas Condensate Field was discovered in 1965.
It is located in the southern part of the Tazovsky District in the YNAA, 220 kilometres from Novy Urengoi. The Zapolyarnoye field is unique, with reserves reaching about 3 trillion cubic metres of gas. It differs from other fields with its small area, as it covers 8,745 hectares. It is 50 kilometres long and 30 kilometres wide. This makes it possible to use only three gas-processing plants.
In 1992, Yamburggazdobycha (now Gazprom Dobycha Yamburg) and the Tazovsky District administration signed an agreement on the field's development.
On March 31, 1994, the field development started.
The Urengoi field has several layers – the Cenomanian, the Valanginian, and the Achimov deposits. The Cenomanian deposits are rich in natural gas, the Valanginian deposits are rich in gas, oil and gas condensate, and the Achimov deposits are rich in highly valuable gas condensate and oil.
On September 2001, the first portion of gas was extracted from the Cenomanian deposits, which are mostly natural high-energy methane concentrations at depths between 1,000 and 1,700 metres.
On October 31, 2001, the first gas-processing plant (UKPG-1S) producing 35 billion cubic metres per year was commissioned.
In December 2002, the UKPG-2S gas-processing plant with a capacity for producing 32.5 billion cubic metres per year was commissioned on the field.
On December 19, 2003, the UKPG-3S gas-processing plant was launched. Its project capacity is 32.5 billion cubic metres per year.
In 2004, the field began to produce 100 billion cubic metres per year.
In April 2011, they began to extract gas and condensate from the Valanginian deposits on the field – Valanginian gas sits at depths between 1,700 and 3,200 metres and includes considerable proportions of ethane, propane and gas condensate.
Currently, the development of the Cenomanian deposits continues on the field. Additional wells have been built. They will make it possible to raise gas production up to 115 billion cubic metres per year.
Simultaneously, the development of the Valanginian deposits is being conducted. In April 2011, Gazprom commissioned a gas and gas condensate plant on the Valanginian deposits on the field.
The plant includes a gas and gas condensate processing unit (UKPG-2V) and 61 wells. In 2012, the plant reached its project production capacity – about 6.5 billion cubic metres of gas and 1.3 million tonnes of gas condensate per year.
It is planned to increase gas production to 15 billion cubic metres, and to raise gas condensate production to 3 million tonnes. Additional wells and one gas and gas condensate processing unit (UKPG-1V) will be built to this end.
So in the future, total field production will reach 130 billion cubic metres of gas per year and 3 million tonnes of gas condensate per year.
