1. A completion assembly being assembled by grips of rig components at a rig and being configured to position in a borehole, the assembly comprising:
a plurality of wellscreens, each of the wellscreens comprising a basepipe, each of the basepipes defining a bore and comprising:
a coupling configured to couple adjoining ends of the basepipes together, the coupling configured to be gripped by the grip of a tong device of the rig components,
an intermediate section disposed between the ends of the basepipe and defining a plurality of intermediate perforations in communication with the bore, and
a primary filter disposed at the intermediate section and being configured to filter communication from the borehole to the intermediate perforations, the ends of adjoining ones of the basepipes coupled together defining a blank area between adjoining ones of the primary filters,
wherein at least one of the wellscreens comprises a plurality of end perforations defined in at least one of the ends of the basepipe for the at least one wellscreen and being disposed in communication with the bore of the basepipe, the at least one end comprising:
a foil disposed on the at least one end adjacent the end perforations, the foil being configured to filter communication from the blank area to the bore; and
a gripping section disposed on the at least one end adjacent the end perforations, the gripping section being configured to be gripped by at least one of the grip of the tong device and the grip of a completion slip of the rig components, the gripping section and the coupling having exterior gripping surfaces being radially exposed to be gripped by the grips in making up the basepipe having the foil to the completion assembly.
