Abstract
A composition for delaying the cross-linking of water soluble polymer solutions includes a boron source suspended by an organophilic clay in a solution of a non-aqueous solvent. One process of manufacturing the composition includes the steps of first suspending the organophilic clay in the non-aqueous solvent and then suspending the boron source in the organophilic clay- non-aqueous solvent suspension. Another process of manufacturing composition includes the steps of first mixing the boron source and the organophilic clay to form a dry mixture and then suspending the dry mixture of the boron source and the organophilic clay in a non-aqueous solvent. In a method of hydraulically fracturing a formation, a water soluble polymer solution with a pH between about 8.5 and 12.5 and the boron source suspended by the organophilic clay in the solution of the non-aqueous solvent are pumped into the formation under sufficient pressure to cause a fracture in the formation rock.
