摘要： The present invention involves methods of using particulates coated with a tackifying agent that need not be used immediately once they are prepared and that provide increased viscosity when placed into an aqueous fluid. The described methods include the steps of contacting particulates with a tackifying agent to create tackified particulates; contacting the tackified particulates with a partitioning agent to form coated particulates that are capable of being stored for a time period, wherein the partitioning agent comprises a hydratable polymeric material; and, placing the coated particulates in an aqueous treatment fluid whereby the partitioning agent hydrates and increases the viscosity of the treatment fluid.

摘要： Improved methods of preventing the flow-back of particulates deposited in subterranean formations with produced formation fluids are provided. The methods include extruding or injecting a solution or mixture of a particulate solid polymer through a plurality of small diameter ports into an aqueous carrier fluid containing suspended particulate material whereby polymer fibers and strands are formed in the carrier fluid. The polymer fibers and strands mix with the particulate material suspended in the carrier fluid as the carrier fluid is pumped into the subterranean formation. The mixture of the particulate material and the polymer fibers and strands is deposited in the subterranean formation so that the mixture forms at least one permeable pack that prevents the production of formation fines with fluids produced from the formation and prevents the flow-back of the deposited particulate solids, fibers or strands.

摘要： Improved methods and apparatus for completing wells and gravel packing an interval of a wellbore are provided. The methods include the steps of placing a perforated shroud having an internal sand screen disposed therein in the zone, and injecting particulate material into the annuli between the sand screen and the perforated shroud and the perforated shroud and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. The perforated shroud has a flow-controlling means for restricting fluid movement between the casing/shroud and shroud/screen annuli during gravel packing. The flow-controlling means may be comprised of a material installed on a selected number of the shroud perforations which blocks or partially blocks fluid flow through the otherwise permeable wall of the perforated shroud during gravel packing. Preferably, the material is removable after the gravel has been placed, such as by melting or dissolving, to accommodate production flow during the production phase without restriction. Materials suitable for application in the improved methods include magnesium oxide/magnesium chloride/calcium carbonate mixtures, oil soluble resins, waxes, soluble polymers, etc. Other suitable materials employ other mechanisms such as temperature, oil solubility, internal breaker or flow shear stress to remove them.
