Scientific and Laboratory Centre (SLC) of core and proppant analysis is an independent one; it has been accredited for technical competence in compliance with GOST ISO/IEC 17025-2009 regulations.

Scientific and Laboratory Centre of core and proppant analysis is situated in Novosibirsk Scientific Centre. Cooperation with the institutes of Siberian Branch of the Russian Academy of Sciences enables to integrate various disciplines and engineering approaches for the resolution of relevant objectives in the petroleum industry in Russia. 

Scientific and Laboratory Centre of core and proppant analysis was founded on the basis of JSC Geologika manufacturing enterprise, therefore the SLC installations can be promptly adjusted for the needs of particular research with due regard to the customer requests and distinctive features of applied experimental techniques.

SLC provides its customers with the opportunity to directly attend it at the moment of method approbation and while experiments are being carried out.
