Ob. Sobanova et al., Application of hydrocarbons-based surfactants for oil production enhancement in watered-out formations, NEFTY KHOZY, (11), 2000, pp. 20-23
Presented are results of field tests of hydrocarbons-based surfactants SNPH
-9630 and SNPH-9633 in Devonian terrigenous sediments of Romashkinskoye fie
ld. Shown are technological efficiency and prospectivity of such method for
oil production enhancement in watered-out formations at the late stage of
development.
