发明名称 Fluid identification system and production and use thereof
摘要 A method of identifying a fluid, the method including the step of: (a) adding a fluid identification system to a fluid, the fluid identification system comprising a plurality of particles, each particle encapsulating therein at least one tracer material having an identifiable DNA, the at least one tracer material being encapsulated by an encapsulation material, wherein the encapsulated DNA has known and unique characteristics to provide a unique identifier for the particles, wherein the encapsulated DNA has a first characteristic of the DNA signature which uniquely identifies a time parameter of the specific fluid into which the fluid identification system or a liquid containing the fluid identification system is added, wherein in adding step (a) the DNA signature and a time parameter of the addition provide a time stamp for the fluid; (b) pumping the fluid into a well, field or reservoir of a hydrocarbon production unit, or a reservoir zone or fracture zone; (c) retrieving the fluid identification system from a sample of the fluid; (d) separating the at least one tracer material from the particles; and (e) analysing the identifiable DNA to determine the identity of the DNA and a time parameter of the fluid between adding step (a) and retrieving step (c).
