Abstract (en)

The present invention relates to a completion system for connecting several screens into a well tubular structure mounted from base pipe sections. The completion system comprises a first screen assembly and a second screen assembly, each screen assembly comprising a base pipe section mounted as part of the well tubular structure having a longitudinal extension, the base pipe section having an outer face, and a tubular screen element surrounding and being connected to the outer face of the base pipe section, the tubular screen element having an outer diameter, and an assembly connection part for connecting an end of the first screen assembly with an end of the second screen assembly, wherein the completion system further comprises a first tubular member having an inner diameter which is equal to or larger than the outer diameter of the tubular screen element, the first tubular member being arranged opposite the assembly connection part so that fluid flowing in through the tubular screen element of one of the screen assemblies flows on the outside of the assembly connection part. Furthermore, the present invention relates to a completion method and a production method for producing hydrocarbon-containing fluid from a reservoir into a well tubular structure.
