The Gemini Retrievable Bridge Plug (RBP) is a high performance mono-bore plugging device which can be set at any required depth in the tubing or casing. Our plug portfolio has gone through an extensive testing program including qualifying plugs to the highest relevant industry standard of ISO 14310 V0 (gas tight).
The Gemini RBP is deployed, equalized and retrieved using conventional well intervention methods. Deployment is achieved in one run, as is the subsequent equalization and retrieval of the plug.
This enables a reduction in both well intervention risk and subsequent operational cost. The plug features bi-directional slips which anchor the plug to the casing/tubing/liner ID prior to pack-off of the element to form the pressure seal, making it ideal for cross flow applications.
The large ‘through bore’ design ensures full equalization occurs prior to retrieval. This also means that secondary devices can be installed onto the lower section of the RBP such as Omega’s remotely activated equalizing valves.
Features
Medium expansion slips and element.
Highly debris tolerant due to innovative equalizing/retrieval design.
Retrieval mechanism enables successful retrieval in one intervention.
Bi-Directional mechanical slips.
Large slip footprint maximizes slip/casing contact area.
Overall length minimized for restricted access deployment.
Set using conventional intervention setting tools, such as Omega’s Hydrostatic Setting Tool (HST).
Option to install a Lower Junk Catcher Extension in high debris environments.
Applications
? Well barrier during well maintenance and workover’s.
? Zonal isolation, water shut off or treatment.
? Pre-installation in completion tail-pipe for packer setting.
? Contingency packer setting.
? Testing of production tubing(s).
Benefits
? Increased operational performance due to setting and releasing mechanisms.
? No specialized retrieval tool required, standard GS pulling tool used to equalize and retrieve.
? Optimized slip design reduces stress loading on tubulars. Controlled setting action, further enhanced with the Omega HST.
?
? Through bore design provides secondary functionality and increased debris tolerance.
