摘要：
A subterranean formation having at least one borehole is treated with an aqueous gel wherein crude oil and water were produced from the subterranean formation through the borehole until the production of crude oil was reduced due to the presence of sandy material restricting the borehole, and the production of crude oil is increased as a result of said treatment as, for example, by producing crude oil and water from the formation at a lower water-oil ratio as compared to the water-oil ratio prior to treatment with the aqueous gel.
