Abstract: A completion pipe comprising a plug arrangement and a method for arranging a completion pipe in a well. The arrangement includes a disintegratable plug element arranged in a plug housing in a pipe string, a seal element arranged to seal between the plug element and the pipe string. The plug element is movable in the axial direction of the pipe string between a first position and a second position.

Abstract: A downhole valve having: a valve body with a longitudinal main passage; an annular chamber arranged in the valve body; at least one valve port extending from the main passage, through the annular chamber and to an outside of the valve. The downhole valve further includes a sleeve disposed at least partially within the chamber. The sleeve is movable in response to an application of fluid pressure to the annular chamber via a fluid channel extending from the main passage to the annular chamber. The sleeve is movable between a closed position in which the sleeve blocks the at least one valve port and an open position in which the sleeve does not block the at least one valve port.

Abstract: A downhole valve has a housing with a longitudinal main passage and at least one valve port extending from the main passage and through the housing, a valve member is arranged in the main passage, the valve member arranged to cover the at least one valve port, wherein at least a part of the valve member is made of a degradable material which is reactive to water or a well fluid, and has a surface coating of a material which is non-reactive to water or the well fluid.
