Lab research in FSUE Arktikmorneftegazrazvedka analytical lab started in 1983, when first geological materials were received while developing Arctic shelf. The main task was and is still obtaining objective information with regard to Oil Formation Physics  and response parameters substantiation for reserves estimation.

The lab is furnished with modern analytical equipment and software (Coretest Systems inc., Scientific and production Company  «Тenakon»,  “VNIIFTRI” core analysis equipment , “Volta”  formation water analysis equipment, «LUMEX» equipment for  formation water analysis and others), from Scientific and Technical Centre “Tvergeophizika” and others), allowing to research the content and properties of reservoir rocks and formation fluids.

The quality of the serviced provided, a rigid many level meteorological control, the level of technique and many-year experience of the lab experts have allowed to gain recognition for the lab within the bodies of the Committee of the Russian Federation for Standardization, Metrology and Certification as well as of Russian Maritime Register of Shipping.

The lab being a diversified branch, makes analysis of the main areas of activities as follows:
