    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. The units have at least a first rock-repulsive unit, which is configured to provide an effect of electrostatic repulsion towards rock, and at least a second detectable unit, which is configured to allow detectability of the tracer; and optionally at least a third unit, which is configured to detect a parameter or features of an oilfield, in particular oil saturation and temperature.

    Abstract: An electro-acoustic transducer includes a tubular body extending a longitudinal direction and having two end portions, opposing each other longitudinally, and internally having a first chamber, sending with the first end portion and a second chamber, on one side adjacent to and in fluidic communication with the first chamber and on the other side ending with the second end portion. The first end portion is closed towards the outside by a membrane applied to the tubular body. The second end portion has openings that put it in fluidic communication to the outside of the tubular body. The first chamber containing electrical windings arranged in succession to each other in the longitudinal direction. The second chamber is filled with a liquid. A movable element is housed in the first chamber and has a permanent magnets packaged and arranged one above the other, with the magnetization alternating and separated.
