A method for gravel packing perforations in a well is described which comprises: (a) introducing an acidizing agent into the formation's nearwellbore area via perforations within the well which acidizing agent is of a strength sufficient to dissolve formation sand or fines in channels contained in said formation and perforations; (b) introducing thereafter a sand consolidation agent into said perforations before said channels are blocked with formation sand or fines; (c) allowing the consolidation agent to remain in the perforations for a time sufficient to form a cement having a porosity sufficient to prevent formation fines from entering said channels and perforations thereby permitting the production of substantially fines free hydrocarbonaceous fluids to the surface; and (d) packing said perforations with sand.
