ROSGEO has completed field work on the water prospecting in Karelia

JSC North-West PGO (St. Petersburg, the enterprise is the part of the ROSGEO state holding) has completed field work on the prospecting and evaluation of underground potable water to provide water supply to the city of Pitkyaranty in the Republic of Karelia. Exploring is conducted under the state contract at the expense of the federal budget. The goal of the project is to find a source with reserves of at least 4.5 thous. m3/day by the C1 + C2 categories. Taking into account the complex hydrochemical conditions of the territory and the variable data on the well production specific yields, the work was carried out in two stages – prospecting and appraisal works.

‘Potable water supply provided by underground sources has a number of unconditional advantages over surface water supply’, – said Oleg Vasin, Managing Director of JSC ROSGEO. ‘First of all, they are protected from external exposure.’  In most parts of the area under survey, the natural quality of water does not meet drinking water supply standards. Our task is to prepare a resource base for solving this problem by means of a protected underground source.

Based on the results of testing for underground waters inflow carried out in 2016, preliminary data on the hydrodynamic parameters of promising aquifers were obtained and the quality of their resources was studied. The complex of geophysical studies made it possible to obtain a differentiated filtration characteristic of the section, to identify the intervals of water inflows, and to determine the indicative mineralization of groundwater.

Geological work performed in the first half of 2017, allowed to correct the received data. All field works at the site are completed. Now the process of creating a mathematical model for the territory is under way, within which the epignosic and forecasting tasks for reserves estimation will be accomplished, including the calculation of protective sanitary zones for the proposed operation of water intakes on the identified promising subsurface sites.

The report must be submitted to the customer before the end of the year.

ROSGEO is a Russian multi-industry geological holding company, which offers a full range of geological exploration services from regional surveys to stratigraphic drilling and subsoil monitoring. The holding company boasts unique expertise, particularly in marine geology and shelf operations.

ROSGEO was established by Decree No. 957 of the President of the Russian Federation dated 15 July 2011 on the basis of Tsentrgeologia, one of the oldest exploration companies in Russia. ROSGEO is a fully state-owned company.

The enterprises within the holding company operate in all eight federal districts of Russia. ROSGEO includes 53 enterprises located across the country. A total of more than 1,000 fields and deposits have been discovered by the holding’s companies, including major hydrocarbon and solid mineral deposits and fields such as the Astrakhan field (2.5 trillion cubic meters of natural gas), the Tengiz field (3.1 billion tonnes of oil), the Kovykta field (1.9 trillion cubic meters of natural gas), the Sukhoi Log deposit (about 2,000 tonnes of gold), the Kursk Magnetic Anomaly, and many others.

 ROSGEO’s subsidiaries have rich experience in implementing projects abroad: dozens of new fields and deposits have been discovered in Asia, Europe, Africa, and Latin America.

 ROSGEO clients include such companies as Gazprom, Rosneft, Lukoil, Severstal, MMC Norilsk Nickel, Itera, NLMK, Sibuglemet, BP, Chevron, and many others.

North-West Production Geological Association (former Saint-Petersburg Complex Geological Expedition) is a fast developing company providing a full range of geological exploration: surveying, prospecting, estimation, exploration, hydrological and geological/environmental investigations. In 2011 the company was acquired by Rosgeologia Holding.
