Resin Coated Prepacked Sand Control Liner

摘要

A novel and simple sand control technology has beendeveloped and field tested featuring a prepacked linerconsisting of thermosetting resin coated sand grains bonded byheat onto a perforated steel base pipe to form a solid, porous,and permeable cylindrical sand liner that can be installed intoa wells requiring sand control. The Resin Coated PrepackedSand Control Liner is a cost effective tool that can be appliedto a variety of wellbore situations requiring remedial orprimary sand control. The liner does not use wire wrappingand is constructed using standard oil field tubulars andcommercially available thermosetting resin coated sand. Theliner fills a need in certain sand control situations that cannotbe solved using conventional technology. The Resin CoatedPrepacked Liner is used with and without secondary gravelpacking, depending on the well and reservoir conditions. TheResin Coated Prepacked Liner is currently installed in onewell in the Long Beach Field, Southern California as a fieldtest in a problem well that has historically experiencedwellbore sand accumulation and repeated pump failures.Since installation in June 2002, the well has been sand freewith an unexpected increase in oil production.
