A unique Urengoi field is located between the 65th and 68th degrees of northern latitude crossing the Polar Circle. The field is 220 km in the north-south direction and from 30 to 60 km in the eastwest direction; the gas bearing area exceeds six thousand square kilometres. Hydrocarbon deposits are characterised by a complex geological structure. Three geologic gas-bearing units are distinguished. The Senomanian formation is the upper level at 1030-1260 meters in depth. It is being developed. The Neocomian formation is the middle level and contains gas, oil and condensate reservoirs with 22 strata. They are at 1700-3100 meters in depth and are being developed.

The bottom level presents challenges of geological conditions with gas, oil and condensate reservoirs at 3550-4000 meters in depth and is still under exploration.

In 1997 through geological exploration, the increment of gas reserves reached the level of 60% of its production for the first time at the Urengoi field. The figures for condensate exceeded the volume of production 10 times as much. The jubilee year has been marked by discovery of the North-Samburg oil field.

But more intensive exploration drilling is still ahead. Development of the new fields (Tab-Yakhinskoye and Pestsovoye) will be carried out according to the comprehensive plan with turn-key construction of well clusters and introduction of technological innovations into well construction. As it has always been - the most important thing in geological exploration is expansion of the Association's natural resource. For this reason a few prospecting wells will be drilled at the East-Yamsovey, South Pestsovoye and North-Samburgskoye fields in 1998.

In March 1966 the first drilling rig was erected on wellR-2 of the would be Urengoigas and condensate field.
