OREANDA-NEWS. In fulfillment of a state contract, Severo-Zapadnoye PGO JSC (the affiliate of Rosgeologia Holding, Saint-Petersburg) has completed prospecting and assessment of ground water resources to cover the utility and potable water demands of Baltiysk in the Kaliningrad Region.

The geologists carried out a comprehensive environmental hydrogeological survey in the area, wildcat and appraisal well drilling, logging and testing, as well as hydrochemical testing. The project included testing of chemical, radiological, and bacteriological composition of the aquifers and the surface water bodies of the Kaliningrad and Gdansk bays of the Baltic Sea. In the course of the entire project both ground and surface water levels were monitored as well as water quality.

“The challenges of the geological and hydrochemical conditions of the area under consideration result from its location on a narrow sand bar separating the Kaliningrad Bay from the Gdansk Bay of the Baltic Sea,” - Oleg Vasin, the Managing Director of Severo-Zapadnoye PGO JSC says. - “The hydrogeological conditions are also aggravated by a buried valley cutting the onshore area from the south-east to the north-west and extending into the Baltic Sea. The methodology of the survey took into account these peculiar features.

In view of the complicated hydrological, geological, environmental, and hydrogeological conditions the ground water reserves were assessed with the help of a numerical modeling method based on creation of geofiltration and geomigration models.

Reserves estimation included water balance analysis of the area revealing its inlet and outlet flows, the contribution of the involved resources from the bays, and a natural flow interception ratio.

After the state expert review the Baltiysk prospective water abstraction area has received the designation: Novobaltiysk Potable Ground Water Deposit.

According to the original assessment the utility and potable water reserves to be supplied to Baltiysk, Kaliningrad Region, over a 25-year period, have been approved in the amount of 4,000 m3/day including С1 reserves of 1,000 m3/day and C2 reserves of 3,000 m3/day.

Rosgeologia 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.

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

The enterprises within the holding company operate in all eight federal districts of Russia. Fifty three subsidiaries of Rosgeologia are 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.

Rosgeologia’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.

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

Severo-Zapadnoye Production Geological Enterprise JSC (formerly 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.
