Pipe base Screen is a type of screens used for deepwater wells, oil wells and gas wells where a high collapse and tensile resistance are required, and while we still in need for the merits of the wire wrap screens for efficient sand control, as It merges the efficiency of the wire wrap screens and the strength of a pipe.
The first component of this type of screens is the base pipe which can be manufactured using any type of carbon steel or API standard pipes or any grade of stainless steel (304, 304L, 316, 316L,Duplex …etc ) according to each single well needs.
Then it gets perforated using a customized multi holes perforator machine to get very accurate holes in place as per a prior design.
