Gravel Pack (GP), High Rate Water Packs (HRWP) and Frac-Packs (FP) are various methods to provide long term sand control in Cased Hole Completions. In gravel pack operations, a screen is placed in the wellbore and the surrounding annulus and perforation tunnels are packed with high permeability gravel/proppant properly sized to prevent the ...
A unitary gravel pack multi-pathway tube includes a body; a gravel slurry flow passage defined within the body; and a control line protection projection extending from and supported by the body, the projection extending laterally from the body relative to an extent of the flow passage and method.
The SC-XP gravel-pack and frac-pack system can manage your extremely high-horsepower pump jobs, allowing high proppant volumes to be pumped without damaging your tools or the casing. System integrity ensures opening and enlarging flow paths. The sand control system enables long, horizontal, openhole gravel packing without disturbing the filter ...
Screen completion is usually adopted in horizontal wells of heavy oil sandstone reservoir, however, frequent pump inspection even long term shut-off caused by thin sand production of some wells bring serious impact on production. For this reason, the gravel pack completion sand control technology in horizontal well is created on the problem of thin sand prevention and control in horizontal ...
Efficient gravel pack formation control must take into account a number of formation and reservoir characteristics, gravel size, and well performance objectives. Numerous authors1–3 ave ...
Hence, the gravel pack is designed to control the load-bearing material; no attempt is made to control formation fines that make up less 2 to 3% of the formation. This calculated gravel-pack sand size range is compared to the available commercial grades of gravel-pack sand.

A primary objective of gravel packing is formation stabilization while causing minimal impairment to well productivity. A steel screen is placed in the wellbore and the surrounding annulus is packed with prepared gravel specifically sized to reduce the passage of formation sand.

the pack. In cased hole, the plug may be com-pletely drilled out to leave gravel-filled per-forations. Alternatively, the pack may be drilled out to the top of the perforations/ open hole so that hydrocarbons are pro-duced through the pack. A narrow hole can be drilled through the pack to provide a conduit to reduce drawdown through the pack.
An auger gravel pack assembly for installation in a gravel packed well includes a fluid loss control closure member retained in a body disposed in a tubing assembly or "work string" between the gravel pack screen and a running tool and cup-packer assembly. A ball-type closure member is retained by releasable fingers connected to a piston which is responsive to fluid pressure applied through ...
Since most gravel pack quality control devices rely on the usually sizable difference of density between borehole fluid and packing material, they may not be suitable for gravel-pack operations involving high-density borehole fluids and/or low-density gravel packing material.
Gravel-pack packer for sand control. Save rig time with a single-trip sand control solution for single- and multizone completions. QUANTUM HSB Gravel-pack dual-bore and sealbore packer. Enable efficient performance in high-rate production wells, dual-bore completions, and gravel pack completions.
Filling the annulus between the screen/casing (or open hole) with gravel-pack sand is essential to the control of formation sand production. To ensure that the annulus is filled completely around the screen, centralization of the screen is required. In cased-hole completions, weld-on, blade-type centralizers are normally used.
The gravel pack functions as a down-hole filter, allowing reservoir fluid movement but preventing production of formation sands. Bridging of the borehole wall against the gravel pack is the key to the control of sand movement. When effective bridging is achieved, sand and other solid particles carried by the formation fluids are
Premium sand control alternative when conventional gravel pack is not feasible. Direct Wire Wrap Screen Direct Wrap is manufactured directly over the basepipe with mechanical properties (tension, compression, torque ratings) similar to the basepipe.
However, when high gravel concentrations are used, the pack can be completed in a few minutes and little time is available to effectively control the operations. 1.2.4 Perforation prepacking Conceptually, the ideal cased hole gravel packing method is to separate the perforation and annular packing process, i.e. to prepack the perforations.
The GOES GPPU (Gravel Pack Pumping Unit), for example, is a truck-mounted blending, filtering and pumping combination unit which reduces equipment, travel and personnel costs. Of course, all units are available as truck, trailer or skid mounted unit and come with …
Gravel packing for sand control is the second application of both natural sand and synthetic proppants in oil and gas well stimulation and completion and is carried out in oil-, gas-, and water-production wells; water-, steam-, and chemical-injection wells; underground gas-storage wells and occasionally also mineral-leaching and geothermal heat-exploitation wells.
Handil field is a mature oilfield located in East Kalimantan Indonesia, operated by TOTAL E&P Indonesie (TEPI). By 2012, there were several wells completed with Gravel Pack completions that were producing sand during production phase. This condition created a hydrocarbon production limitation around 3700 bopd from three oil wells.
Pack Deep-Zone (FPDZ) System is a frac-pack rated sand control placement technology. It is specially configured for deep completions where work string stretch and drag make downhole tool manipulation more challenging. The system offers extended tool ... SECTION 1: Gravel Pack and Frac-Pack Systems COMPLETION SERVICES TECHNICAL DATA Minimum ...
Until recently, stand-alone screens were the predominant sand-control measure for horizontal openholes. However, operators now gravel pack more of these wells because many screen-only completions ...
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. This occurs particularly in formations made of sandstone, limestone, and ...
Selecting a particular sand control technique depends on the type of well completion and the formation's geo-mechanical properties. Gravel packing is the often preferred and very reliable sand control technique [3]. Gravel packing involves packing the annulus between a steel screen placed in the wellbore in the open or cased
Gravel pack design & evaluation. A gravel pack is simply a downhole filter designed to prevent the production of unwanted formation sand. The formation sand is held in place by properly sized gravel pack sand that, in turn, is held in place with a properly-sized screen. Source: PetroWiki.
