Mitigation of sand production in sandstone reservoir using thermally expandable beads

摘要

Systems and methods for producing fluids from a subterranean well include introducing expandable beads into a target region of a production zone of the subterranean well, the expandable beads being formed of thermally expandable material in an unexpanded condition with a first diameter. A radial confining stress is increased and a hoop stress is decreased within the target region by thermally expanding the expandable beads so that the beads are in an expanded condition with a second diameter, the second diameter being greater than the first diameter.
