Method for extracting precursor acids from calcium naphthenate deposits

The present invention is a system for the extraction and quantification of tetraprotic naphthenic acids present in oils, precursors of the formation of calcium naphthenates, which are potential formers of deposits, causing of damage to pieces of equipment used in the oil production industry.
