Halliburton unveils nanoparticle wellbore sealant to boost wellbore stability

(WO) – Halliburton Company introduced the BaraFLC Nano-1 wellbore sealant, a nanocomposite suspension that boosts wellbore stability. The new sealant works with Halliburton’s existing conventional and high-performance water-based fluid systems to create a tighter, more secure seal that decreases fluid loss into the formation.

Halliburton’s BaraFLC Nano-1 sealant uses nanoparticles to reduce interaction between filtrate and reactive shale formations, preventing pore pressure transmission. This helps strengthen wellbore integrity, which can extend drilling time and efficiency.

Sold as a liquid, BaraFLC Nano-1 sealant reduces bag waste and airborne dust. It comes in ready-to-inject form and easily mixes with water-based fluids, which can reduce non-productive time.

“In many areas around the world, our customers require high-performance water-based fluid systems to maximize the value of their wellbore. We developed nanotechnology that results in a step change, compared to conventional sealants and rivals the performance of oil-based fluids,” said Toby Dixon, Senior Vice President
