Abstract
A method of improving the flow of a proppant pack or gravel pack comprises: introducing into a subterranean formation or a well a plurality of ceramic particles, the ceramic particles comprising about 0.1 wt. % to about 25 wt. % of a rare earth-containing compound, based on the total weight of the ceramic particles; and forming a proppant pack or gravel pack comprising the plurality of the ceramic particles; wherein the proppant pack or gravel pack improves fluid flow as compared with a reference proppant pack or gravel pack formed from otherwise identical ceramic particles except for being free of the rare earth-containing compound.
