Petrophysical laboratory of "Uzbekgeofizika" JSC has been conducting research for more than 50 years. The main task was and remains to obtain objective information in the field of reservoir physics and substantiate the petrophysical and filtration-capacitance parameters of reservoir rocks for calculating the reserves of oil, gas and gas condensate fields.
To date, the laboratory is equipped with modern analytical equipment and software (Coretest Systems inc. (USA)), which allows studying the composition and properties of reservoir rocks both in atmospheric and reservoir conditions.
The quality of the services provided, the level of technical equipment and the long-term experience of the staff allow the Laboratory to cooperate fruitfully with organizations such as:
The laboratory, being a multidisciplinary unit, conducts analyses in the following main areas of activity:
- Cleaning and preparation of core samples for research
- Photographing the core in daylight and ultraviolet light
- Carrying out gamma-spectral and gamma-density logging on a full diameter core
- Determination of the bulk density coefficient
- Determination of the coefficient of mineralogical density
- Determination of the coefficient of open porosity by various methods.
- Determination of absolute gas permeability in parallel and perpendicular to bedding
- Determination of the coefficient of porosity and permeability in reservoir conditions
- Determination of the coefficient of residual water saturation by capillarimetry
- Determination of the coefficient of residual water saturation by centrifugation
- Determination of the fluid permeability coefficient of the rock
- Definition of electrical resistivity at 100% and variable water saturation
- Determination of Electrical Resistivity when modeling the current water saturation (5 steps) (atmospheric conditions)
- Velocity of longitudinal and transverse waves in atmospheric and reservoir conditions
- Determination of the coefficient Effective permeability (with residual water saturation)
- Calculation of dynamic elastic properties of rocks in reservoir conditions: shear modulus, Poisson's ratio, volumetric compression modulus, Young's modulus
- Determination of wettability of rocks
- Determination of residual water saturation by capillarometry and recording of capillary pressure curves with calculation of relative phase permeabilities in the "gas-water" system
- Definition of phase permeability in the "oil-water" or "gas-water" system
- Determination Evaluation of the impact of drilling fluid penetration on the filtration properties of rocks
Results:
- Construction of petrophysical dependencies
- Justification of boundary values
- conclusions based on the results of petrophysical studies
