    • Method for dewatering, pressure testing, hydrotreating, suppressing methane hydrate formation and suppressing solution freezing point in pipeline operations have been disclosed, where the solution used in the operations includes an effective amount of a metal formate salt. The metal formate salt solutions have a low viscosity, have a high density, have a low metals corrosivity, are non-volatile, have a low solubility in hydrocarbons, are readily biodegradable, have a low toxicity, are non-hazardous, have a low environmental impact, have a freezing point depression property forming water/formate eutectic point mixtures, and have a water-structuring and water activity modification property.
