Abstract: A backup comprising a gage ring having frustoconical surface and a groove in the frustoconical surface. The backup further includes a segment having a nose engaged with the groove, the segment having an element portion with an overlap finger and a finger receptor and a gage portion with an overlap finger and a finger receptor. A wedge ring is in contact with the segment and a retainer member is disposed to retain the segment. A method for using the backup and a system are included.

Abstract: A retrievable in-flow control device (ICD) including a device body having a first end, a second end, an outer surface extending between the first end and the second end, and an internal flow path. A wireline connector is arranged at the first end. A latch mechanism is provided on one of the wireline connector and the device body. A flow control port extends through the outer surface to the internal flow path. An equalizer member including a first flow path for passing a first fluid and a second flow path for resisting flow of a second fluid. The retrievable ICD also includes a flow control device establishes a selected pressure drop of the first fluid through the retrievable ICD.

Abstract: A valve for subterranean whipstock service has a side port and a through passage with a biased movable sleeve to shift between circulation mode into the annulus and flow through mode for setting an anchor and then feeding window mill nozzles. The valve is run in when in circulation mode to allow operation of a measurement while drilling device. When the whipstock is properly oriented the pressure is increased to break a shear pin to allow a spring to bias the sleeve to the flow through position. The shifting of the sleeve opens a bypass passage around the restriction orifice that was first used to build pressure to break the shear pins that let the sleeve move under spring bias. As a result the spring can hold the sleeve in position despite high flow rates needed to remove cuttings from the mill as the window is opened.
