According to preliminary data, the year 2020 saw the сompany perform:
- 3D seismic surveys covering more than 5,000 sq.km
- drill over 57,000 m of rock formations in Russia
- including technically challenging wells with depths reaching 4,500 m
This resulted in reserve additions exceeding 480 billion m3, which is substantially higher than the production volume (452.6 billion m3).Therefore, Gazprom’s reserve replacement ratio has been exceeding 1 for as many as 16 consecutive years.
The bulk of geological exploration carried out by Gazprom takes place near the Yamal Peninsula, in the east of Russia, and on the continental shelf.
Specifically, the Yamal gas production center expanded its resource base in 2020 thanks to the discovery of the 75 Years of Victory field (202.4 billion m3 of gas reserves) on the Yamal shelf of the Kara Sea.
Moreover, new data obtained in the course of drilling an exploration well proved that the productivity of the Leningradskoye field is much higher than anticipated.The company is also conducting follow-up exploration at Bovanenkovskoye and Kharasaveyskoye, which are the key fields of the Yamal center, and studying the Tambeyskoye field.
As part of developing the Yakutia gas production center and shaping the Irkutsk gas production center, Gazprom is performing geological exploration at the Chayandinskoye and Kovyktinskoye fields.
In order to improve the efficiency of geological surveys, the company employs cutting-edge technologies, including digital ones, thereby obtaining better data and optimizing production processes.
To that end, the company is developing an integrated information environment for geological, geophysical and field data, which allows the specialists to monitor and analyze the ongoing surveying and development of fields across their entire lifecycles in a comprehensive manner.
