Abstract:
A method for consolidating an unconsolidated formation containing sand, comprising the steps of:providing a well drilled to an unconsolidated formation; providing a substantially non-acidic consolidation fluid comprising a fluid suspension of nanoparticles comprising an inorganic component having an affinity for the sand grains of the formation and an organic component which allows for polymerization bonding of the inorganic component to contacting sand grains of the unconsolidated formation under substantially non-acidic conditions, wherein said nanoparticles have an average particle size between about 1 and about 200 nm; and flowing said consolidation fluid through said well and into said unconsolidated formation so as to contact said nanoparticles with the grains of said unconsolidated formation.
