Abstract
Experimental studies and pilot test results of developed stimulation technologies with petroleum sulfonate indicate economic benefits of the use of Karpatol achieved due to significant reduction in interfacial tension surfactant-hydrocarbon (oil, condensate, petrol); increase of residual oil displacement factor, destruction of water-oil emulsions, partial permeability build-up of contaminated rock samples, advanced permeability of surfactants in nonuniform permeable and hydrophobic strata, influence on the rheology of viscous oils, improvement of wells development after stimulation, high technological efficiency of stimulation technologies using Karpatol, increase of production index after treatment.
