This paper presents an experimental study of improved oil recovery from fractured tight cores by huff-n-puff of the aqueous solutions of 3-pentanone. The huff-n-puff experiments with different 3-pentanone concentrations were compared. Naturally sulfate-rich brine of low salinity was used as the injection brine. Results show that the 3-pentanone solution recovered more oil from the matrix than the injection brine alone. The improved oil recovery by 3-pentanone increased to 28.6% of the original oil in place as the 3-pentanone concentration increased up to 2.85 wt% in the injection brine. However, the huff-n-puff experiment with the 1.07-wt% 3-pentanone solution showed the highest efficiency measured by the mass ratio of the produced oil to the injected 3-pentanone, 11.1. That is, an optimal concentration of 3-pentanone appeared to exist.
