ISO-Flex™ High-Expansion Retrievable Bridge Plug
Establish V0-rated barriers below tubing restrictions
Keep zonal-barrier operations moving fast and smooth—even when faced with challenging restrictions, high pressures, and high temperatures. ISO-Flex combines an extremely narrow-diameter profile with powerful hold capabilities to easily establish powerfully strong, temporary-or-permanent isolations below tight wellbore restrictions.
for interventions within extreme restrictions
Quickly gain access behind challenging constraints with the plug featuring an ultra-thin profile that keeps operations moving fast and without time-consuming hang-ups.
Reduced maximum-running OD
drifts through standard tubing completion architecture and sets in next larger size tubing (i.e.: passes through 3.5-in. tubing to set in 4.5-in. tubing).
Optimized slip/casing contacts
minimize potential for tubing or slips damage. Flow areas entering and exiting the plug exceed the incoming area of plug ID for maximized efficiency.
provides confidence with key features based on ISO-Premium Bridge Plug with over 3,000 successful field runs.
Simple, robust design
is debris tolerant for long-lasting service deployments within remote, HPHT environments and is suitable for field redresses.
for high-quality, V0-rated well validations
Gain confidence in challenging well environments with powerful mechanical barrier featuring large, direct-to-the-wellbore equalization area that is ideal for sub-hydrostatic applications.
Certified well-barrier strength
qualified to ISO 14310 11D1 V0 and TR2385 to 5,000 psi (35 Mpa) up to 275°F (135°C) for reliable barrier holds.
improves equalization through plug center and not around the slips for reduced risk of retrieval difficulty and pressure differentials.
reduces risk of pressurization blown up hole and enables shift-down to equalize and shift-up to release.
Retractable back-up rings
contain the element to prevent extrusion and delivers enhanced element reliability during pressure reversals.
ISO-Flex Overcomes Well Obstruction
SAVES Six Rig Days
Successful Temporary Abandonment in Injection Completion Where Standard Slickline Plug was Impossible
During an abandonment workover operation for an offshore injection-well operator in Brazil, ISO-Flex technology was successfully deployed to overcome a restricted wellbore – allowing operations to continue quickly and smoothly, saving the operator six rig days.
