‘Shielding’ Spacer Prevents Cement-Imperiling Losses

Impact Fluids Solution recently published an article describing the next-generation in Wellbore Shielding Spacer (WBS) technology. "The core of the technology is the uniquely engineered ultralow invasion additive that essentially deposits a thin but impermeable “shield” across a wide range of matrix pores and microfractures, thereby preventing or minimizing losses. Comprising a proprietary combination of polymers, solids and other materials, the non-damaging WBS additive creates an extremely low-permeability barrier, minimizing fluid and pressure invasion. The seal has no adverse impact on formation permeability, as evident in return permeabilities of 90% to 95%."
