Enhancement of the imbibition recovery by surfactants in tight oil reservoirs

Abstract Hydraulic fracturing technology can significantly increase oil production from tight oil formations, but performance data show that production declines rapidly. In the long term, it is necessary to increase the development efficiency of block matrix, surfactant-aided imbibition is a potenti...
