ABSTRACT:
An aperture design minimizes erosion on the surrounding casing and to the aperture itself and is particularly effective in fluid injection wells where large volumes of fluids over a long period of time with entrained solids are expected to be pumped through. The preferred design is an elongated shape with a flaring wider in the downhole direction. The downhole end of the opening features an exit that flares in the downhole direction with multiple slopes with an arc transition. Other options for the opening configuration are envisioned.
