Injection Well Cleaning Fluids and Related Methods
Methods can include introducing a cleaning fluid into a near-wellbore zone of an injection well penetrating a subterranean formation, wherein the cleaning fluid includes: 0.5 wt % to about 5 wt % of a surfactant blend comprising an alkoxy carbonate surfactant and an internal olefin sulfonate surfact...

| description | Methods can include introducing a cleaning fluid into a near-wellbore zone of an injection well penetrating a subterranean formation, wherein the cleaning fluid includes: 0.5 wt % to about 5 wt % of a surfactant blend comprising an alkoxy carbonate surfactant and an internal olefin sulfonate surfactant; salt water having a total dissolved solids (TDS) of about 15,000 mg/L or greater; and 0 wt % to about 0.05 wt % of an organic acid; and dispersing a hydrocarbon from the near-wellbore zone in the cleaning fluid. Compositions for cleaning a near-wellbore zone of a subterranean formation can include 0.5 wt % to about 5 wt % of a surfactant blend comprising an alkoxy carbonate surfactant and an internal olefin sulfonate surfactant; salt water having a total dissolved solids (TDS) of about 15,000 mg/L or greater; and 0 wt % to about 0.05 wt % of an organic acid. |
