The paper will include an introduction of dissolvable plug and its development in oil & gas upstream business. Dissolvable plug is a customized tool, and it could be modified by controlling its chemical compound to adjust its dissolving rate. In addition, slim version dissolvable plug is a plug solution with dissolvability originally brought out to overcome the downhole restriction challenge (ID of SSD), namely to pass the downhole restriction then to set in the original casing ID. A case study of its application in offshore squeeze cementing job will be analyzed in this paper, from the plug designing perspective to operational data recap to prove its benefits. Conventional plugs will leave the bottom of the plug body downhole after plugs slip losing integrity during the milling operation, and the remainder leaving downhole will choke the well production or even block the well, however, dissolvable plug remainders will dissolve itself downhole, which will not have an impact on the production.
