Dissolvable bridge plugs are specialized devices designed to temporarily seal off sections of a wellbore during drilling or completion operations. As the name suggests, these plugs dissolve over time when exposed to specific fluids, such as water or other wellbore fluids. This feature makes them particularly advantageous compared to traditional mechanical plugs, which require retrieval after their
