Abstract

The invention relates to an annulus pressure buildup mitigation device (202) configured to be fitted on the outside of a casing string, the annulus pressure buildup mitigation device (202) comprising a tubular sleeve (203), an enclosed space within the tubular sleeve (203) and a pressure sensitive device (204), wherein the enclosed space is sealed by the pressure sensitive device (204) and the pressure sensitive device (204) is configured to unseal the enclosed space and thereby put the enclosed space in fluid communication with the outside of the tubular sleeve (203) if pressure outside of the tubular sleeve (203) exceeds a pressure threshold.
