Abstract: A new class of multifunctional tracers has been synthesised for use in the oil industry, specifically during waterflooding operations. They are used either in a traditional way (i.e., mapping the connections of oilfield selections) or to provide information on important physical-chemical parameters (such as oil content, temperature and rock permeability) useful for optimizing the oilfield management and subsequent improvement/increase in oil extraction. The multifunctional tracers have a polymer chain having a plurality of units different from one another and recurring along the chain and having respective specific functionalities.
