North-Urengoy field discovered in 1970, and is located in the Northern part of the West-Siberian plain. It is a part of Bolshoi Urengoy group of fieldswhich includes the largest gas fields of Russia - the Urengoyskoye, Yamburgskoye, Zapoliarnoye, Yen-Yakhinskoye, Pestsovoye fields.
North-Urengoy field
North-Urengoy field is related to the fields of Nadym-Pur-Tazovsky region. These combine to form a huge energy resource linked by the integral oil and gas pipeline system.
The field lies within the administrative borders of Purovsky and Nadymsky regions of Yamalo-Nenetsky autonomous area of Tyumen province. The field is situated 80 km (50 miles) from the nearest settlement (the small town of Tazovsky) and 200 km (125 miles) from the city of Novy Urengoy.
According to estimates by DeGolyer and MacNaughton (as of January 1, 2006) the total geological reserves of the field that we are developing comprise:
- sales gas - 367.311 bln. m3
- condensate - 63.739 mln. tons
- oil - 38.916 mln. tons
