The silica sand core of Greensand Plus™ allows it to better withstand operating conditions in waters that are low in silica, TDS and hardness. Thus, if you currently are using manganese greensand and are feeding sodium aluminate, you will likely be able to eliminate the aluminate feed by switching to Greensand Plus™.
Pre-packed screen provide excellence service of sand control in oil, gas and water wells for its unique construction. Pre-packed screen is a modification of pipe-based wire wrapped screen. Its addition of a modular gravel pack makes it especially suitable for sand control where conventional gravel packing fails.
Oct 02, 2018· Shouldn't be a problem using small slots and small sand for a well that uses a small pump. No you can't cut .020 slots yourself. May have to purchase from a driller who can buy from a local supply house. Same with a sand point. The screen size should be small enough to hold back the sand, but the smaller the screen size the more restriction.
Finding Material: The best material is coarse silica sand and fine gravel material which is usually found in river-beds or ocean beaches. Separate the desired size fraction by using two screens which have slot sizes of 3 and 6 mm (1/8 and 1/4 in). Put the screens on the top and bottom of a strong wooden frame with the coarse slot screen on top.

The oldest and most popular method of filtration is sand. Sand filters share two things in common: 1) When in the filtration mode, water always flows from top to bottom; 2) They all have some sort of lateral or under drain with slots to hold back sand while allowing clean, filtered water to pass through.
The primary application for this type of screen would be in unconsolidated formations where a gravel pack is economically undesirable, and its successful completion is in question. Variperm Pre-Packed Screens consist of an inner and outer wire wrapped screen packed with high quality smooth well rounded silica sand.
Highest efficiency due to generously sized screens and optimum slot passing speed; Less wear because of low slot passing speed in screens and efficient sand removal in cleaners; Specially designed screen bars with optimized profile in order to obtain highest efficiency and production

Jan 02, 2020· Sand production is a problem that affects hydrocarbon production from unconsolidated sandstone reservoirs. Several factors, such as the strength of the reservoir, its lithification and cementation and reduction in pore pressure, may cause sand to be separated from the rock and transported by hydrocarbons to the well. Producing sand commonly causes erosion and corrosion of
screen refers to that structure in a well, which protects the borehole, but allows the entrance of water. In this sense, screen is a filter. The durability and efficiency* of a well depend to a large degree on its design, construction procedures and selection of casing and well screen. However, casings
media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging. KEYWORDS: sand/
