Hydrothermal synthesis of nitrogen and sulfur co-doped reduced graphene oxide anchored cuprous oxide nanocomposite for enhancing rheological and filtration performance of water based drilling fluids
{{output}}
Borehole instability driven by reactive shale hydration and excessive filtrate invasion remains a critical challenge in drilling operations. To address this, we synthesized a novel nitrogen and sulfur co-doped reduced graphene oxide/cuprous oxide (N,S-rGO/Cu2O... ...
