文章摘要
Abstract: Sand production from loosely consolidated reservoirs is one of the critical issues in the oil and gas industry all around the world that can cause many problems, such as erosion of surface and well equipment, sand accumulation in wells and operation facilities, buckling of casing in cased-hole wells and well productivity reduction. Sand production control methods include restrictive production rate, mechanical methods (slotted liner, wire-wrapped screen, pre-packed screen, frac-pack, gravel pack, high-rate water pack) and chemical consolidation that chemical method is considered for more effectiveness in sand production alleviation due to increasing formation strength in near wellbore region. This review provides an overview on the laboratory and filed operation investigations of chemical remedy for sand production. Some used chemical agents and more common laboratory tests for evaluating the chemical performance in sand consolidation are introduced in this paper. Furthermore, the results of field operations and injections of chemicals into the desired formation are also reported. These results show that the chemical sand consolidation is more effective in newly perforated wells which have no sand production experience and have a production history of less than two years. Finally, it was concluded that the main challenges in applying this method are permeability and capillary force reduction around the wellbore and selective injection into the targeted formation layers.
