A leading offshore operator in the Middle East required a tailored solution to shut-off an open-hole formation taking excessive fluid losses in an extended-reach horizontal well. Zonal abandonment was required to properly finalize drilling operations and commence completion activities in a safe and timely manner. The main challenges associated with this application were as follows:
IPI’s tailored solution for this challenge was an 8” OD Permanent Inflatable Bridge Plug configured as a Cement Retainer (PIBP-CR). The BHA was configured with the following custom-made components in order to increase reliability:
The PIBP-CR was deployed to setting depth and it was inflated by applied pressure. The setting sequence was finalized by the activation of a shut-in valve mechanism which permanently locked in the inflation pressure within the bridge plug. Zonal isolation across the bridge plug was obtained by activating a bi-directional dual flapper sub which was functioned by pulling an inner-stinger at the time of disconnection. IPI’s DuraGRIP™ inflation element technology was used to provide leak-free bidirectional anchoring and the integrity of the shut-in valve was thoroughly tested against flow erosion based on the maximum expected flow rates and volumes prior to the job.
The PIBP-CR was set in the horizontal section of the well and zonal losses were successfully shut-off in a single run, allowing the operator to carry on with programmed completion activities. The job was successfully executed in a safe and timely manner without operational issues, which generated substantial savings in operational costs and rig time.
