An inlet device to a separator including a generally tubular outer wall and a generally tubular inner wall. The walls define at least a part of a first annular path between them. An inlet opening provides for the passage of a fluid through the outer wall into the first annular path. At least one communication channel provides for the passage of a fluid from the first annular path into the second annular path. At least one movable closing element provides for at least partial closure of the fluid passage from the first path into the second path. The communication channel(s) is/are arranged to extend along the outside of the inner wall downwards from the first path into the second path, wherein the second path is arranged below the first path.

Inlet device and a method of controlling the introduction of a fluid into a separator

An inline well fluid separator is movable for pigging operations. The separator assembly has a housing with an inlet port and an outlet port. A separation unit is carried within the housing. The separation unit has an operational position in alignment with the ports to cause well fluid to flow through the separation unit. The separation unit will move to a storage position within the housing outside of the flow path to enable a pipeline pig to pass.

Piggable separation system

Subsea wells are drilled and completed with an offshore floating platform in a manner that allows simultaneous work on more than one well. A first well is drilled and casing. Then a tubing hanger is run through a drilling riser and landed in the wellhead housing. Then, with the same floating platform, the drilling riser is disconnected and moved to a second well. While performing operations on the second well, the operator lowers a production tree from the floating platform on a lift line, and connects it to the first wellhead housing. An ROV assisted subsea plug removal tool is used for plug removal and setting operations required through the production tree.
