WELLBORE SAND CONTROL METHOD

A slug of solution, comprising a linear polymer (e.g. polysulfone) dissolved in a "good" solvent (e.g. morpholine) is emplaced in the near-wellbore region of an unconsolidated sand reservoir. A second slug comprising a poor solvent for the polymer (e.g. water) is pumped into the region to...

description	A slug of solution, comprising a linear polymer (e.g. polysulfone) dissolved in a "good" solvent (e.g. morpholine) is emplaced in the near-wellbore region of an unconsolidated sand reservoir. A second slug comprising a poor solvent for the polymer (e.g. water) is pumped into the region to contact the first slug. The linear polymer is precipitated and forms a three-dimensional network of interconnected strands extending through the fluid flow channels between the sand grains. The network functions to consolidate the sand.
