BoKure™ GHOST Degradable Elastomer for Downhole Sealing Applications

BoKure™ GHOST is a degradable elastomer compound designed as the sealing element in frac plug assemblies for harsh downhole oil and gas environments, including aqueous brine conditions. GHOST degrades completely after use, minimizing the need for well intervention by reducing or eliminating drill-out and recovery.

BoKure™ GHOST Degrades Differently

When other degradable elastomers deteriorate, they can become highly viscous, gumming up with stray particles in the well. This can accumulate into a mass that flows back to the surface, causing a blockage that may need to be recovered. This defeats the purpose of using a degradable and results in unscheduled downtime. As BoKure™ GHOST degrades, it breaks down into flowable, non-binding, non-clogging particles that do not need to be recovered.

Verified Performance Under Downhole Conditions

Our degradable material is designed to provide a stable 3 to 6 hour operational life, followed by a quick and consistent material deterioration. Our GHOST compound is developed to work in aqueous brine environments at an ideal temperature of 80°C; variation in temperature will reduce or extend operational time. It has been third-party tested and proven to be able to withstand up to 10,000 psi with appropriate design considerations. The degradation rate is independent of KCI (potassium chloride) concentrations and will degrade asefficiently in 3% brine as it would in 15% brine. Additional degradation temperatures compounds are being developed.

(1) As with most degradable materials, BoKure™ Ghost will start to deteriorate at any temperature when exposed to moisture. For this reason, all products manufactured from BoKure™ Ghost are vacuum sealed to prevent premature degradation. The ideal rate of degradation for this material occurs at 80°C or above.

The temperature range listed is a general guideline and final suitability will depend on various application conditions. To ensure this material meets customers’ final requirements and safety demands, we recommend customers conduct their own testing.
