The Research and Testing Center was established under the aegis of LLC «Gazprom geotechnology» (former name Podzemgazprom Ltd.) on the 30th of November, 2004.
The Research and Testing Center measures the following physical and mechanical properties of rocks, construction and other materials:
volume weight and specific weight;
ultimate uniaxial compression strength;
ultimate tensile stress;
ultimate bending strength;
creeping indices in uniaxial and triaxial stress state (long-term strength, shear deformation and volumetric deformation intensity during tests and breaking);
retained strength (after rock breaking);
cohesion (short-term, long-term, residual);
angle of internal friction (short-term, long-term, residual);
degree of fragmentation;
modulus of elasticity and modulus of deformation;
Poisson ratios and lateral deformations ratios;
ultimate strain under uniaxial and triaxial compression;
Besides that, based on the results of physical and mechanical tests, complete certificates of rock strength and deformability are obtained.
The Research and Testing Center performs the following types of work in the area of tests of physicochemical properties and composition of rocks, underground water and construction materials:
study of macro and microstructure of rock salt samples from different fields in order to evaluate rock processing behaviour (strength, solubility, permeability, etc);
evaluation of tightness of underground reservoirs by means of heliometry;
measurements of insoluble inclusions: kinetics of settlement, sediment compactibility, falling velocity in brine and aquatic media, grain size distribution by sediments and by drain;
analyses of chemical and mineral composition of core samples of salt-bearing section and dolomite and anhydrite rocks recovered from exploratory and evaluation wells (analysis for 10 parameters: humidity, insoluble inclusions, ion concentration of sodium, calcium, magnesium, potassium, chlorine, sulphate, hydrocarbonate and bromine);
analyses of chemical composition of mineralized water strata and aqueous extracts from soils (analyses for 14 parameters: density, dry residue, pH, ion concentration of sodium, calcium, magnesium, potassium, iron, chlorine, sulphate, carbonate, hydrocarbonate, hydroxide and bromine);
design and experimental evaluation of compatibility of brines and stratum mineralized waters;
evaluation of the forecast composition of brines by the wash stages, based on experimentally determined chemical salt composition;
tests for the content of magnesium compounds in caustic magnesite powder: oxide, hydroxide, carbonate; amount of acid-insoluble impurities;
quality evaluation of caustic magnesite powders by the content of magnesium oxide burned (dead-burned) particles therein;
photocolorimetric determination of cobalt ion concentration in sodium chloride brines.
The Research and Testing Center performs the following ecological calculations for the “Environment Protection” project section:
mass emission of harmful substances from different sources;
emission dispersion in the atmospheric air in order to determine sanitary protection (buffer) areas;
solid waste amount during drilling operations, conservation and abandonment of wells;
payment for nonpoint discharge of pollutants;
hazard class of harmful substances.
The Research and Testing Center also develops technical standards for techniques of measurements having no metrological provision.
