red flint sand & gravel is specifically engineered for gravel packed wells. engineering firms and well screen manufacturers specify red flint because of its superior chemical and physical properties. red flint well pack gravel media is used for in-ground wells to form a barrier between the screens and the natural deposit of the geological formation.
sand control systems. time tested, reliable and field proven solution for your sand control needs. gravel/frac packing is an effective method for completing unconsolidated sandstone wells from producing sand. superior offers complete™ systems for a standard stack-pack, as a single-trip in multizone, or in ultra-deepwater completions.
sand control pumping equipment offerings. accurately proportion gravel with low-viscosity carrier fluid at low rates and concentrations. continuously and precisely mix gravel-pack slurry in offshore environments. to download this file you first sign in to your schlumberger account.
both open hole and casing gravel pack completions have the same mechanism of sand control. under open hole gravel pack completion, the gravel bed at the bottom of the borehole acts as a sand filter—it only allows fluid to pass through, not formation sand.
gravel packing. gravel packing is a sand-control method used to prevent the production of formation sand. gravel packing is used in conjunction with hydraulic fracturing, but at much lower pressures. formation sand is produced from the breakdown of formations where wells are located.
gravel packing is currently the most widely used sand-control technique for completing wells. more than 90% of all sand-control completions are gravel packs. because of its flexibility, almost any well at any deviation can be gravel packed. the exception is tubingless completions where clearances do not permit the use of conventional tools.
there have been several published techniques for selecting a gravel-pack sand size to control the production of formation sand. the most widely used sizing criterion1 provides sand control when the median grain size of the gravel-pack sand, d50 , is no more than six times larger than the median grain size of the formation sand, d50 .
our sand control services begin with an in-depth analysis of the reservoir and well conditions. based on your unique needs, we then provide specialized surface and downhole equipment, including gravel pack packers and screens, surface pumping equipment, fluid systems, and filtration systems, all supported by completion service so you can maximize value from your assets.
gravel packing sand control technology scope of application this technology is suitable for offshore and onshore formation sand control when sand production is caused by unconsolidation, high oil and gas drainage pressure, high viscosity crude oil, depleted zones and incursion of extraneous fluids.

provides remedial sand control for repairing failed completions with gravel packs or other sand control screens; enhances existing sand control methods and prevent plugging due to small formation sand and fines movement; readily adapts to changing reservoir conditions by
gravel pack is a common sand control technique used in many formations with unconsolidated or poorly consolidated sands. sand production can often be readily achieved by proper sizing
almost every sand control solution involves the installation of a pipe-based filter that is either gravel packed or left as a 'stand alone' screen. gravel packing has evolved over more than 70 years, but still involves complex fluid and gravel pumping operations.
as pumping continues, carrier fluid leaks off into the formation or through the screen and back to surface. the gravel pack creates a granular filter with very high permeability—about 120 dar- cies—but prevents formation sand entering the well (below). gravel packs are not without their draw-
our gravel-pack systems give you a strong defense against damaging sand and fines in a variety of downhole settings. from unconsolidated to tight sand formations, in openhole or cased-hole wells, and for both conventional and unconventional applications, we deliver an unsurpassed level of gravel-packing and frac-packing performance and efficiency.

there are two major sand control operations: frac pack and gravel pack (table 1). gravel pack is widely used in open-hole completions, especially for long horizontal wells. in cased-hole wells, fracturing is preferred for well stimulation with sand control, which requires high treatment pressures and slurry pump rates.
gravel pack systems are suitable for unconsolidated to tight sand formations, both open-hole or cased-hole wells, and for both conventional and unconventional applications. the advantages of an open-hole gravel pack are increased reliability and productivity from the well. asia pacific likely to emerge as the largest sand control solutions market
