Minimal sand production; Low production rates; Economically viable well service; Rate restriction. Restricting the well's flow rate to a level that reduces sand production is a method used occasionally. The point of the procedure is to sequentially reduce or increase the flow rate until an acceptable value of sand production is achieved.
