Abstract: Sulfate scales, including barium, calcium, strontium, and radium sulfates, are known for being difficult to remove. Mineral acids are typically ineffective and the acid forms of chelating agents have limited efficacy. Specific salts of ethylenedienetetraacetic acid and diethylenetriaminepentaacetic acid including: Li5DTPA, Na5DTPA, K5DTPA, Cs5DTPA, Na4EDTA, K4EDTA, TEAH4DTPA, and TBAH5DTPA, show improved performance over the free acids. Additional enhancer molecules may be added to improve the effect. These compositions are particularly useful for removing sulfate scales from surfaces and oilfield equipment.

Abstract: Treatment fluids for use in subterranean formations, particularly sandstone and other siliceous formations, may contain a source of fluoride ions to aid in mineral dissolution. In some cases, it is desirable to generate the fluoride ions from a fluoride ion precursor, particularly a hydrofluoric acid precursor, such as a boron trifluoride complex. Methods described herein comprise providing a treatment fluid that comprises an aqueous base fluid, a boron trifluoride complex, and a chelating agent composition, and introducing the treatment fluid into a subterranean formation.
