A gravel pack is the standard method to control sand production. The most important factors behind installing gravel pack are: 1. Size the gravel to stop sand movement but allow pass of fine particles. 2. Place gravel in a tight pack with the radius of the pack as large as possible.
Our product line includes choices of washing equipment for your specific application: sandscrew washers for fine materials; coarse material washers for screened aggregate sizes; logwashers with twin shafts and heavy-duty paddles for tough conditions; rotary drum scrubbers for raw materials; and, screening equipment with water spray bars.
If your washing machine sounds like it's full of gravel when the drum is turning it can be worrying. You're probably already thinking about buying a new appliance. But, in some cases, this issue has an easy to fix solution. Keep reading as I explain all of the likely causes to your washing machine sounding […]

As with all our gravel- and frac-pack services, our integrated system approach includes downhole tools, surface pumping and blending equipment, screens, fluids, and optimization services to maximize …
Rotary Scrubbers are used to wash crushed rock, ore, sand, gravel, construction aggregates and oil sands. They are high-capacity, high-retention machines that can …
Learn about the different types and sizes of gravel for your project with our Gravel Size Chart and pictures. Compare gravel types and find the best one for you.
A gravel pack is a way to increase the surface area you are drawing well from and, in turn, increase your well's production. Gravel packs may be used by themselves or in combination with a well screen. During the drilling process you have temporarily evacuated the sand from a small area at the bottom of the well.
Abstract. Correct sizing of Gravel packs for sand retention in Gravel Pack and Frac Pack completions has been a controversial topic for many years dating back to the 1960's. One of the earliest studies completed, and still most often cited, was by Saucier in 1974. Saucier proposed sizing the gravel based on the median size of the formation …

Place gravel and stones around the sides and bottom of the casing. Fill the void between the casing and the surrounding gravel with a 50/50 mixture of sand and bentonite slurry. Install a packer and …
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 …
SAZ Gravel Pack System uses field-proven products and services to enhance well life by mitigating sanding challenges in unconsolidated reservoirs. The single-zone, cased hole gravel-packing system uses a simple and robust tool design.
Summary. Cased-hole gravel packing is commonly used to control sand production from oil and gas wells. The success of a cased-hole gravel-pack job depends on the ability to effectively pack perforation tunnels, which act as conduits between the reservoir and the wellbore for hydrocarbon production.This project presents a systematic …
The SC-XP™ select gravel- and frac- pack system from Baker Hughes gives you a versatile, cost effective, and efficient sand control solution for land, inland water, and shelf applications via a single platform. In addition to featuring the robust SC-XP setting tool, crossover tool, and washpipe valve, the system leverages proven packer and gravel …
This can be used to turn cobblestone into gravel, gravel into dirt, and dirt into sand, allowing those resources to be farmed. It can also turn some blocks into cracked variants. Ores can also be partially processed but will need the washer (below) to …
The gravel pack provides a prefilter to keep fine sand and sediment from reaching the screen and well. This allows the use of a screen with larger openings, improving the flow rate. The packing gravel must be carefully sized or it can get clogged with sediment and block the water flow.
Gravel placement techniques. Gravel packing consists of installing a downhole filter in the well to control the entry of formation material but allow the production of reservoir fluids. The gravel-packed completion is perhaps the most difficult and complex routine completion operation because it consists of many interrelated completion practices.
Extend well production with gravel- and frac-pack services, fluids, screens, ICDs, and tools for openhole and cased hole wells.
The first air raises the water level in the well, and forces water out through the swab into the gravel pack. This turbulence tends to surge the gravel and help wash the wall cake in. It …
Our inventory of washing equipment will improve the quality of your finished products when clay and silt contaminate sand, gravel, and quarry materials.
The Mitchell Crossover Tool is a field proven service tool used in gravel pack operations to mitigate sand production in unconsolidated reservoirs. This single zone gravel packing system uses a simple and robust tool design to achieve a circulating gravel pack.
Gravel pack equipment and tools. A myriad of gravel-pack systems are available to handle virtually any conceivable well condition. Gravel pack completion equipment is the …
Gravel packs are a well construction method that allows drillers to achieve maximum efficiency with minimum sand production.
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 …
The gravel design criterion proposed in the literature has been used as a guideline for gravel design, and it has typically provided adequate sand control for field operations. This study introduces a Sand Retention Test (SRT) setup to evaluate the sand production and fines plugging in wellbores completed with open-hole gravel-pack (OHGP).
The most practical choice for single-zone completions is often the conventional PerfPac cased hole gravel- and frac-pack service. Optimized for your well and environment, the service uses sequential trips to run the sump packer, perforate, deploy the screen and gravel-pack assembly, and then deliver the pumping service. Software-aided treatment …
Gravel packing: How does it work? Oil and gas wells undergo completion operations before being able to produce. In the case where the surrounding reservoir is poorly consolidated, a popular method is open hole gravel packing. This proceeds by pumping a sand suspension along the annular region between the borehole wall and a …
Other 4P gravel-pack system components include • Weatherford's heavy-duty, dual-piston hydraulic setting tool to reliably carry in high-weight gravel- pack installations; • an easy-to-operate model 4P crossover service tool to enable dependable and economical gravel- pack operations at low-to-medium rates and pressures.
AquaPac openhole gravel-pack service uses brine to carry and place gravel around preinstalled screens. It successfully addresses the challenges presented by many highly deviated openhole wells: low fracture gradients, reactive shales, and unstable boreholes. The entire process—design, execution, and evaluation—is supported by proprietary …
The output of drum gravel-washing machines is 40–200 cu m/hr, with a drum diameter of up to 2,500 mm. In some designs, gravel washing-machine drums are fitted with additional sorting devices with perforated surfaces on which the material is fractionated.
