The RIBP has an innovative design with an equalization mechanism allowing the operator to equalize pressure across the packer, before activating the deflation mechanism. There are several methods of deployment such as drill pipe, coiled tubing and capillary tube.
To perform a sectional abandonment of a salt well at target depth under highly deviated well conditions, enabling isolation of the existing wellbore section and facilitating the creation of a sidetrack for continued drilling operations.
A retrievable inflatable bridge plug (RIBP), equipped with a hydraulic disconnect, was deployed on drill pipe to a depth of approximately 3,000 meters. The inflatable design enabled effective sealing in challenging well geometries, while the hydraulic disconnect allowed reliable release after setting. The RIBP was deployed with a bull nose to facilitate permanent isolation of the selected wellbore section prior to sidetrack operations.
The RIBP was assembled with a hydraulic disconnect and made up to the drill pipe. The assembly was run in hole to the target depth under highly deviated well conditions.
The plug was set using a controlled two-step pressure sequence until full inflation and setting were achieved at 60 bar. The hydraulic disconnect was activated at 90 bar, allowing release from the drill pipe.
The plug was tagged with 2 tons to confirm correct placement and integrity. Cement was pumped on top of the plug to ensure permanent isolation of the abandoned section.
The operation enabled the creation of a sidetrack and continuation of drilling activities.
