Barrier Behind Casing (BBC)
Replace cement, eliminate SCP
The QuartzPack P&A Advantage
➀ELIMINATE SCP FOREVER
Self-healing properties prevent micro-annulus formation. No fractures, no shrinkage, no sustained casing pressure issues that plague cement-based barriers.
➁MAINTAIN PERFECT OVERBALANCE
Continuous 2.15 SG hydrostatic head never degrades. Permanent pressure control against gas migration and cross-flow between zones.
➂NO OPERATIONAL DELAYS
No waiting for cure time between casing runs. Set casing, place QuartzPack, continue operations immediately. Massive rig time savings on every section.
➃FUTURE-PROOF YOUR WELL
Easy casing retrieval when needed. No milling required - QuartzPack flows away cleanly. Preserves wellbore access for future interventions.
➄ADAPT TO WELLBORE CHANGES
Reshapes automatically with thermal cycling, pressure testing, and mechanical stress. Maintains seal integrity throughout well life regardless of downhole activity.
BBC Solutions Explained
Multiple deployment options including conventional displacement and our innovative PushPack technique. We select the optimal method based on your well geometry and operational constraints, working with your existing cementing equipment.

Temporary abandonment that actually worked
HPHT well (915 bar, 175°C) temporarily abandoned with 230m QuartzPack plug. After 26 months, easily pumped out with open-ended drill pipe. Saved 7 rig days vs. milling cement. Well completed successfully with no formation damage.
