METHOD OF COMPLETING POORLY CONSOLIDATED FORMATIONS |
摘要 |
A method for completing an unconsolidated interval in a subterranean formation, includes a consolidation step. The consolidation step is performed by injection of an aqueous solution of colloidal particles with a pH modifier and/or an ionic-strength modifier. A hard gel is formed that holds the particles together. The consolidation is followed by hydraulic fracturing. Diversion towards regions of lower permeability may be enhanced by the use of micrometric particles. |
