Method of opening cased well perforation
Patent
·
OSTI ID:5152784
This patent describes a method of opening perforations in a cased well flow, the cased well having a maximum safe wellhead, using a treating fluid and perforation sealers. It comprises determining the number of perforations in the casing which have already been opened by injection of treating fluid into the well but have not yet been and establishing a treating fluid flow rate such that the treating fluid flows through the already opened perforations which have not yet been sealed at a velocity which is at least as high as the minimum effective sealing velocity but the maximum safe well head pressure will not be exceeded when the next of the already opened perforations which have not yet been sealed is sealed.
