Method of controlling proppant flowback in a well

摘要

Hydrocarbons are obtained from a fractured formation by pumping particulate proppant through a perforated casing (10) into the fractures, installing an expandable screen (22) in the casing (10), expanding the screen in the casing, the screen mesh being such as to block proppant flowback from the fractures whilst maximising hydrocarbon production.
