An expandable sand screen device is described comprising in various examples a rolled-up piece of screen material which is configured to be at least partially unrollable to expand diametrically when located in a wellbore. A piece of screen material may be rolled up to form an expandable roll. In some examples, the expandable sand screen device is run into the wellbore on a running tool and allowed to partially unroll once released from the running tool.
