Annotation:
The results of testing clay inhibitors and inhibitory properties of water-based drilling fluids (WBDF), oil-based drilling fluids (OBDF) and process fluids (PF) using the methodology according to RD 39-00147001-773-2004 Appendix 8 (RD 39-2-813) of JSC "NPO Burenie" are presented. Comparative express-analysis of inhibitory properties was performed for aqueous solutions and dispersions of mineral, organic (including asphaltenes), and organic-mineral compounds of various concentrations used for the preparation and processing of WBDF, OBDF, and PF.
