Gravel packing is a technique for the control of sand. The increasing application of directional drilling both on and offshore has led to completion difficulties. Gravel packing in deviated wells has caused difficulties, especially at hole angles above 40 degree . This paper discusses the application of a computer-based prediction package named GRAVPACK. The design of gravel packs is discussed with reference to the impact of specific wellbore parameters such as casing size, hole angle and required carrier fluid density upon packing efficiency. For annular and perforation packing, comparison is made between the use of a high viscosity/concentration slurry technique and a low viscosity/concentration gravel packing system.
