Abstract

A novel fracturing fluid called VAS (anionic surfactant type) has been successfully developed and applied in both oil and gas wells in China. VAS can not only minimize matrix damage caused by modifying the rock surface charge and lowering water-sensitive and water-lock. This paper presents the stimulation mechanisms of the novel VAS fracturing fluid. Field demonstrations indicate that, for the wells using the VAS fracturing fluid, the production increased remarkably and stabilized longer than the wells using water-based Guar gum fracturing fluid. Averagely, the production for the wells using this VAS fracturing fluid increased by 120% compared with the wells using acidic fracturing fluid and increased by 89% compared with the wells using ethyloic fracturing fluid.
