HOUSTON -- Halliburton has unveiled the Evo-Trieve bridge plug, a retrievable monobore plugging device that does not require a predetermined setting restriction for locating or sealing within the production completion.
The new product is V0-qualified per ISO 14310 to 7500 psi at 275° F (135° C) and its design includes large slip and element footprints to provide pressure-holding capability in unsupported casing. Debris tolerance has been verified through a comprehensive flow loop testing program, the company says.
The device can be deployed using conventional slickline with the DPU downhole power unit and can be retrieved with industry-standard GS pulling tools.
• Supplied with H2S packing element system as standard for well deployment and reduced inventory management
• Debris tolerance provided by element positioned above slips complemented by a large internal diameter pressure equalizing feature to resist plugging
• Improved body lock ring system retains element pack-off force during pressure reversals across the plug
• Robust slip system permits no over expansion in set position while remaining mechanically locked in retracted position when plug is released.
• Time savings delivered through single-trip wire line equalization and plug retrieval operations
• Easily adapted to existing modular extensions for extreme debris environments
• Easy access top guide sub ensures retrieving tool engagement in highly deviated well profiles.
• Minimized tool diameter and retained packing element offers improved running speeds and operational performance within deviated well bores and access through tubing restrictions
• Reduced operational costs as tool retrieved by readily available industry-standard GS pulling tools
• Simplified compact design requires no special assembly tools ideally suited for well site conversion and remote location operations
• Suitable for deployment in all well types using slickline, DPU downhole power unit, electric line, coiled tubing, tractor and workstring operations.
