Recent advances on friction reducer for slickwater fracturing of shale gas reservoirs

Abstract

The slickwater fracturing of shale gas reservoirs is a novel fracturing techniques developed in recent years and the slickwater fracturing fluid is a key technique. Compared with the traditional gelatinous fracturing fluid, the slickwater fracturing fluid has the advantages of high efficiency and low cost which has been widely used in the completion and production of shale gas reservoirs. As the core of the slickwater fracturing fluid, the friction reducer ultimatly determine the fluids performances. In this review, the reported friction reducer and our own work are summarized and discussed, and the development trends are evaluated.
