Patent number: 11970657Abstract: A scale inhibitor squeeze treatment is enhanced by injecting a pre-flush solution into a wellbore, where the pre-flush solution includes at least one organic carbonate solvent, such as a dialkyl carbonate and/or a cyclic carbonate. The use of an organic carbonate solvent can help prevent the pre-flush solution emulsion formation, help avoid water-blocking, and enhance scale inhibitor adsorption. The use of an organic carbonate solvent also permits the pre-flush solution to be free of water, in one non-limiting embodiment.Type: GrantFiled: May 26, 2022Date of Patent: April 30, 2024Assignee: Baker Hughes Oilfield Operations LLCInventors: Sankaran Murgesan, Jerry J. Weers, Onome Ugono, Jeffrey A. Russek, Dong Lee

Patent number: 11898093Abstract: 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.Type: GrantFiled: May 26, 2023Date of Patent: February 13, 2024Assignee: Baker Hughes Oilfield Operations LLCInventors: Lirio Quintero, Jeffrey A.
