Sand consolidation method
Patent
·
OSTI ID:6626655
This is a new and improved sand consolidation method wherein an in-situ curing of a resinous fluid is undertaken. This method does not require that the resinous fluids be catalyzed at the surface of the well or well bore as is the case in previous methods. This method consists of, first, pumping an acid-curable consolidating fluid into the unconsolidated sand or earth formation and, secondly, pumping an oil overflush solution containing a halogenated organic or other organic acid or delayed acid-producing chemical. A small quantity of diesel oilspacer may be used between the plastic catalyst solution. The overflush functions to remove permeability, and its acid or acid producing component promotes subsequent hardening of the remaining film of consolidating fluid. Trichloroacetic acid and benzotrichloride are satisfactory to add to the overflush solution for curing the resins. (17 claims)
