Abstract
A sand screen for installation in a well includes a flow-through element having a center line running in the longitudinal direction of the flow-through element; and a filtration device. The flow-through element has an internal cavity extending over at least parts of a length of the flow-through element. There are a plurality of openings over the length of the flow-through element. The openings, via the filtration device, provide communication between an outer surface of the flow-through element and the internal cavity. The sand screen is flexible in a radial direction and in an axial direction.
