摘要

A SYSTEM FOR COMPLETING WELLS IN UNCONSOLIDATED SUBTERRANEAN ZONE 5 A SYSTEM (10) FOR COMPLETING GAS WELLS IN UNCONSOLIDATED SUBTERRANEAN ZONE FOR PREVENTING MIGRATION OF SAND WITH FLUIDS PRODUCED THEREFROM IS PROVIDED. THE SYSTEM (10) INCLUDES A WELL BORE (15) COMPLETED WITH SAND SCREEN (20), AT LEAST ONE FLOW SEGMENTATION MEANS (25) THAT PREVENTS FLUID FLOWS FROM ONE SEGMENT (23) TO 10 ANOTHER SEGMENT (23) ALONG THE SAND SCREEN (20), AND A TUBING (30) WITH ELEVATED THICKNESS AT PREDEFINED POSITION. NATURAL PACKING OF THE SAND IS THEREBY ACHIEVED ALONG THE SAND SCREEN (20) WHICH ACTS AS A GRAVEL PACK TO THE SYSTEM (10). 1 5
