ABSTRACT:
An organometallic compound which is the reaction product of (a) a zirconium halide or oxyhalide, (b) a polyol and (c) an alpha-hydroxy acid is claimed. The preferred polyol is sorbitol and preferred alphahydroxy acids are citric, malic or lactic acid. The compounds find use as cross-linking agents in fracturing fluids employed in the hydraulic fracturing of oil or gas-containing subterranean strata. The claimed compounds can be used to produce a slow or delayed gel formation in such fluids.
