Water well screen pipe | Sand Control Screen

  The water well screen is an important component of a well that allows water to flow into the well while preventing sediment and other debris from entering. The screen is typically located at the bottom of the well, near the aquifer. This is done to ensure that only clean water is collected and that any sediment or dirt is filtered out. The screen is typically made from a perforated pipe or other type of material that has small openings to allow water to pass through while blocking sediments from entering. Abter well screen is manufactured with a continuous v-shaped slot to reduce the entrance velocity of water and encrustation rates. Besides, Filson well screen has a large surface area without clogging, thus provide superior filtration performance. Well screen slot size selection is a critical step, typically based on the particle size analysis of the formation sample. With the standard slot size range from 0.005” to 0.5”, Filson well screen can control sand particles and silt from the well perfectly.   Advantages of Water Well Screens 1. The V-shape section plane of water well screens creates the continuous slot, which can avoid blockage and make sure of the unimpeded water. Read more

Pre-packed well screen | Wire Wrapped Pre Packed Sand Screen

Pre Packed Sand Screen contains perforated base pipe, inner and outer screen jackets and graded sand between the jackets. It is a modification of wire wrapped screen which is used in well sorted sand or stand-alone completion. Graded sand, with or without resin coating, is considered as a filter for reservoir particles. Wire wrapped pre Pre Packed Sand Screen is used in wells where conventional gravel packing is not feasible or economical. The thickness of gravel layer can be varied to meet special requirement. What Is the Function of Gravel Pack? Gravel packing is one of popular sand-control technique used in oil, water and gas wells. It stabilizes the borehole and filters the sand from the flow, only allowing very fine particles in. Pre Packed Sand Screen wire wrapped sand screen brings it into full play in maximizing production as well as controlling the sand.   Diameter: 168mm Material: stainless steel,carbon steel,etc Slot: 0.2mm End Connection: thread,coupling,etc thickness: 10mm Pre Packed Sand Screen PRODUCT SPECIFICATIONS Base Pipe Gravel Pack Perforations Screen OD (in.)

Slotted Casing Pipe | Slotted Liner Well Screen – API 5CT
Slotted Liner pipe

  1. Introduction of Slotted Casing Pipe Casing pipe is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Slotted casing pipe is a type of casing pipe that has slots machined into its surface. These slots are used to help control the flow of water, oil, and gas in a well bore. The slotted casing pipe is designed to allow water, oil, and gas to flow through the slots while preventing sand and other debris from entering the well bore. Slotted casing pipe is commonly used in oil and gas wells, water wells, and geothermal wells. 2. Types of Slotted Casing Pipe There are two main types of slotted casing pipe: open slot and perforated slot. Open slot casing pipe has slots that are cut into the surface of the pipe in a straight line. These slots are usually spaced evenly apart and are typically about 1/4 inch wide and 1/4 inch deep. Perforated slot Read more

Perforated Casing Pipe | Perforated Well Screen Piping

Applications of Perforated Pipe: Perforated well screen is a type of filter used in oil and gas wells. It is designed to control the flow of oil and gas from the well, while preventing sand and other debris from entering the well. perforation in the context of oil wells refers to a hole punched in the casing or liner of an oil well to connect it to the reservoir. Creating a channel between the pay zone and the wellbore to cause oil and gas to flow to the wellbore easily. In cased hole completions, the well will be drilled down past the section of the formation desired for production and will have casing or a liner run in separating the formation from the well bore. The final stage of the completion will involve running in perforating guns, a string of shaped charges, down to the desired depth and firing them to perforate the casing or liner. A typical perforating gun can carry many dozens of explosive charges. Commonly, perforation guns are run on E-line as it is traditional to use electrical signals from the surface to fire the guns. In more highly deviated wells, coiled tubingmay be used. Newer technologies Read more
