SYNERGISTIC VISCOSIFIERS FOR CLAY-FREE, WATER-BASED DRILLING FLUIDS
This abstract first appeared for US patent application 20250101288 titled 'SYNERGISTIC VISCOSIFIERS FOR CLAY-FREE, WATER-BASED DRILLING FLUIDS
Original Abstract Submitted
a water-based drilling fluid can include a first and second viscosifier of a cross-linked starch and a cross-linked acrylamide-based polymer. the acrylamide-based polymer can be crosslinked and optionally include hydrophobic monomers. the viscosifiers create a synergistic effect that imparts desirable properties to the drilling fluid compared to using either of the viscosifiers alone. the viscosifiers can be used as an alternative to other types of viscosifiers such as xanthan gum.
