Cementing Solutions / Spacer SystemS

Shield Bond® Product Line

Cement Spacer System

Built on proprietary chemistry that has been proven in thousands of wells worldwide, the SHIELD BOND® Wellbore Shielding® spacer system goes beyond the traditional spacer functions of separation and mud displacement. SHIELD BOND is specially formulated to allow cement circulation to the programmed top of cement (TOC) where the equivalent circulating density (ECD) window is tight, or in fragile and fractured formations. SHIELD BOND forms a temporary, impermeable shield over the formation, mitigating lost circulation issues during cementing and formation damage. Typical cement spacers are not designed to address pre-existing losses or induced losses.

At the heart of our SHIELD BOND solution is a uniquely engineered ultra-low invasion additive that essentially deposits a thin but impermeable “shield” across a wide range of matrix pores and microfractures to prevent losses. This non-damaging Wellbore Shielding chemistry creates an extremely low-permeability barrier, minimizing fluid and pressure invasion.

SHIELD BOND NXT

SHIELD BOND NXT

Applications
  • Used in fragile and fractured formations
  • When circulating drilling fluid is an issue
  • In wells where pre-job simulations show final ECD near or above the frac gradient
  • When the capability to mix on-the-fly with a weighted spacer is preferred
  • ‍For use in high temperature drilling environments
Advantages
  • Adjustable rheology
  • Extends the frac gradient for higher ECDs
  • Enhances hole cleaning and mud removal prior to cement placement
  • Forms a shield against the formation to limit fluid invasion
  • Reduces cement losses and formation damage
