1. Summary
OBF-AquaSeal is a nanoscale deformable polymers. It plugs the pore throats and microcracks by reducing the pore pressure transmission. It，used in water-based drilling fluids，can effectively reduce the risk of drilling fluid loss and differential sticking in the pressure depletion and sandstone formations.
