Dissolvable frac bridge plugs is mainly composed of dissolvable materials, including rubber, mandrel, cone and slips, etc. The plugs can be set by standard firing setting tools or hydraulic setting tools.
During running in hole, keep the speed as suggested in the operational procedures. After activation of firing by wire-line, the setting sleeves is pushed downward to compress rubber and slips, with mandrel moving in relatively opposite direction. After shearing out the release pin of the adapter, the bridge plug is fully set in place.
The design allows for flow-back operation or production immediately after frac operation. The flows below the bridge plugs can find its pathway through the bridge plugs.
The Dissolvable frac bridge plugs will get dissolved automatically or can be drilled out easily by coiled tubing with miller in case of emergency. And the wellbore will be recovered to full ID.
