A well completion system and method for preventing sand production into a well casing (38) having a perforated interval (42) is disclosed. The system comprises a sand control screen (40) having expandable end sections (60, 62) each of which having an attachment member (72, 74) positioned exteriorly therearound. An expander tool (44) is operably disposed within the sand control screen (40) such that when the sand control screen (40) is positioned within the well casing (38) across the perforated interval (42), the expander tool (44) radially expands the end sections (60, 62) such that the attachment members (72, 74) are placed in contact with the interior of the well casing (38), thereby creating a fluid seal and a friction grip between the end sections (60, 62) and the well casing (38).
