摘要

A method for completing a range of unbound in a training subterru00e1nea and completion method of intervals not consolidated on a subterru00e1nea training ".A method of completion of an interval unbound in an underground formation, incluse a phase of consolidation.The step of consolidation is performed by injection of an aqueous solution of colloidal particles with a pH modifier and / or modifier ion hardness.A gel hard way - and keep the particles together. The consolidation is followed by fraturau00e7u00e3o hydraulics.The deviation in the direction of the regions of low permeability can be increased through the use of micromu00e9tricas particles.
