    摘要: Methods and apparatus for expanding tubulars are disclosed. The tubulars may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

    摘要: A flow control apparatus for use in a wellbore comprises a screen, a first inflow control device and a second inflow control device, wherein a fluid inflow path is provided through the screen and from an outer portion to an inner portion of each inflow control device. A method of cleaning a flow control apparatus such as that described above comprises providing in a wellbore a flow control apparatus comprising at least one screen and at least one inflow control device wherein a fluid inflow path is provided through the at least one screen and from an outer portion to an inner portion of the at least one inflow control device, targeting the at least one inflow control device with a treatment fluid and delivering the treatment fluid such that the fluid flows in a reverse direction along the fluid inflow path.
