Exploration and production

Geological exploration works on the territory of the Republic Tatarstan

RESOURCE BASE The License Fund in the Republic of Tatarstan includes 66 licenses, of which:

  • 36 are licenses for exploration and production of mineral resources,
  • 27 are for geological exploration, including prospecting and evaluation of mineral resources, exploration and extraction of mineral resources,
  • 3 are for geological research, including prospecting and evaluation of mineral resources.

The volume of geological exploration work for licensed areas provided for by licensing agreements is being fully carried out.

In 2017, construction of 9 prospecting and exploration wells was completed, of which 6 are prospecting wells, and 3 are exploration wells.  Productive deposits were discovered in 8 out of 9 wells.

The total volume of prospecting and exploration drilling for the reporting year is

16 003 m,

with that for prospecting, 6,013 m; for exploration, 9,990 m.

The success rate of prospecting and exploration drilling in the Republic of Tatarstan was

89%

IN THE REPUBLIC OF TATARSTAN, IN 2017, TWO DEPOSITS WERE DISCOVERED: KLENOVOYE AND YUZHNO-FERGANSKOYE.

The Klenovoye deposit was discovered at prospecting well No. 2259 where oil was obtained from the carbonate sediments of the Dankovo-Lebedyansky horizon (daily oil output – 8 m3).  C1 + C2 reserves amounted to 134/30 thousand tonnes of geological/recoverable volumes.

Efficiency

1 953,3 RUB/tonne

Yuzhno-Ferganskoye deposit was discovered at prospecting well No. 886. The well is located in the southwestern part of the Agbyazovskiy licensed area. Primary C1 reserves amounted to 151/37 thousand tonnes of geological/recoverables.


Efficiency

1 421,6 RUB/tonne

Prospecting and exploration work in the Republic of Tatarstan was conducted within the CheremshanoBastryksk, Tlyanchi-Tamak, and Stepnoozersk exploration areas and at the Agbazovskiy, Yersubayinskiy, and Sokolkinskiy subsoil areas.

10 structures with prospective recoverable resources in the D0 category (5,249 million tonnes) have been prepared for deep drilling.

In the reporting year, geological and exploration costs in the Republic of Tatarstan amounted to more than RUB 1.5 billion. In 2018, it is planned to invest up to RUB 1,255.3 million in geological exploration in the Republic of Tatarstan, while drilling 18,000 meters of geological material, to continue seismic exploration using 2D methods in the amount of 280 line km, 3D in the amount of 558 km2 in the fields and exploration zones of the Company.
