Abstract
The present Invention relates to novel devices and methods to minimize the production of sand in subterranean environments; in particular, in poorly consolidated formations, sand is often co-produced along with the desired fluid (e.g., oil); sand production is undesirable, hence in the present Invention, elliptically shaped perforations of a particular orientation are created in the casing (or directly into the formation in the case of an uncased wellbore) that lines wellbore drilled through the formation, to improve near-wellbore stability of the formation, hence minimizing sand intrusion.
