Abstract
A004 SURFACTANT COMPOSITIONS WITH HIGH SWEEPOUT EFFECT FOR INCREASING WELL INJECTIVITY AND ENHANCED OIL RECOVERY 1 G.B.FRIDMAN 1 O.B.SOBANOVA 1 I.L. FYODOROVA 1 A.SH. SHAKIROV 2 1 JSC NIIneftepromchim 420045 Russia Kazan N.Yershov st. 29 e-mail: [email protected] 2 JSC “Tatnefteotdacha” One of the important trends in oil field exploitation is operation with the injection well stock involving well completion for injection and maintaining the required injectivity in them. Last years the problem of enhanced oil recovery is particularly urgent along with the challenges of improved oil recovery. The scientists of JSC NIIneftepromchim have been developing the new methods based on
