Sand control method
Patent
·
OSTI ID:5568864
Various sand consolidation methods have been employed to prevent or inhibit sand movement with the fluids produced from hydrocarbon-bearing earth formations. Some of these methods are gravel packing, use of various filter materials, the use of mechanical filter and screens, cementing with preservation of interstices, packing the formation with resin coated particulated solids, wetting the unconsolidated sand with a bonding resin, and placing a resin-treated sand between the loose sand in the formation and the well bore so as to form a screen. The methods have met with varying degrees of success. A dispersion sand consolidation mixture is one in which a consolidating fluid consists of a hydrocarbon carrier, a resin or a resin-forming mixture dispersed in it together with a quantity of particulated solids. This mixture is introduced into the formation and caused to harden, consolidating the solids into a hard permeable mass. (10 claims)
