The mechanical methods for sand exclusion consist on placing a filter that prevents or hinders the entry of sand from the formation into injection or producing wells.
One of the systems used in lower completion to restrain the movement of sand are the perforated or slotted pipes.
These slotted liners are called sand control filters and are used in the direct filtration system, where the slots perform the control of sand granulometry, allowing only oil and very fine sand to flow, retaining solids with greater granulometry than the thickness of the slots.
Perforated pipes for sand control, used on well completion. It is designed for maximum open area to flow (ATF), and lower cost, but without compromising the integrity and safety for the wells production.
We develop and manufacture slotted pipes for well completion, replacing the screen pipes with increased efficiency and cost reduction.
For oil wells which demands a greater open area to flow. It is 20 times higher than the slotted liners. Using core API tubes wrapped with stainless screens.
