Abstract A new system for controlling the problem of sand production in oil and gas wells has been developed and evaluated. This new technique involves placement of a permeable barrier between the formation and the producing wellbore. Slurry is mixed on the surface and then pumped into the well using standard cementing techniques. The permeability of the set material is as high as 5 darcys. Laboratory data, including pumpability, setting temperatures, permeabilities obtained, strength level obtained, etc., are presented. Development of permeability is an inherent characteristic of the slurry, and the system can be tailored for use under virtually all existing well conditions. Results to date indicate that this system should have wide application in the general field of sand control. Introduction The production of sand with oil and gas has long been a serious problem in the oil industry. It greatly complicates and in some cases prevents the production of oil and gas from unconsolidated formations. The influx of sand into the wellbore raises the economic limit on wells for various reasons which are listed below:The replacement or repair of lines, chokes, valves, and meters due to erosion by the flowing sand.Workovers due to the sanding out of wells.Loss of wells due to casing or liners collapsing.Removal of sand and silt from the produced crude.Lowering production rates to decrease sand cuts.Cleaning out of surface facilities.Extra expense of downhole sand control devices, etc.
