There are several cases of wells with potential or identified Annulus Pressure Buildup (APB) problems, especially at offshore fields. Historical failure examples happened at the Marlin field and at the Ponpano A-31 well, both in the Gulf of Mexico. The objective of this article is to present several alternatives for mitigating this problem and the design procedure for each one. In order to find and list those procedures, the literature was initially reviewed. More than 15 techniques were identified and classified in four groups: pressure relief, structural strength increase, fluid compressibility increase and thermal insulation. Afterwards, their design procedures were outlined, as well as its applications. When necessary, the authors performed some tests. Finally, a model well is used as example and the application of each technique is illustrated.
