(57) A new class of multifunctional tracers has been synthesised for use in the oil industry, specifically during watertlooding 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.

(57) It is provided a fluid flow control device for establishing a controllable fluid communication between an external fluid reservoir and a base pipe constituting part of a 5 production string, as well as a production string and a method using such a fluid flow control device. The fluid flow control device includes a top housing covering the primary flow path inlet of the main housing. The fluid flow from the external fluid reservoir flows into top housing in which a fluid flow swirl is induced.
