Thicker gravel packs (3/8” to 5/8”) are available if extra sand retention properties are needed.

Pipe Base Well Screen For Oil and Gas

A pipe base screen, also known as a double-layer screen, is a kind of sand control screen that combines the hydraulic efficiency of a continuous slot wedge wire screen with the strength of a pipe. This screen is a new generation of well screen that has been developed in recent years. It consists of a sand control screen, a perforated pipe, a slotted casing and a stainless steel or carbon steel wire mesh base. This screen is designed for sand control and water filtration and is particularly suited for both vertical and horizontal boreholes. It is a high-efficiency sand control and water filtration screen for both shallow and deep wells, vertical and horizontal boreholes or sand control and water filtration in bore wells. It is a good substitute of the traditional sand control screen for wells with sandy soils or a muddy bottom. Its main functions include: sand retention, formation sand removal and production retaining, can be used in oil or gas well drilling in many countries. This sand screen is using stainless steel base pipe or API 5CT carbon steel casing inside and wire screen jacket to enhance the capacities and high tensile strength loads for deep wells. Its strength is superior to that of a single-layer screen, thus it can be more reliable than a single-layer screen. It’s unique construction and can be used in open hole, standalone or gravel-pack wells, which provides excellent service for oil or gas well drilling.
