    • A process of making observations of a subterranean reservoir penetrated by a wellbore uses distinguishable sets of tracer particles and comprises steps of: (i) delivering a plurality of sets of tracer particles to respective subterranean locations via the wellbore, the particles in each set comprising a tracer substance which distinguishes that set form the other sets; (ii) causing or allowing the tracer substances to flow out from the tracer particles whilst the particles are at the respective subterranean locations; (iii) causing or allowing production of fluid out of said reservoir via the wellbore; and (iv) detecting the presence or absence of the tracer substances in the produced fluid. The tracer substances are sufficiently distinguishable from each other to enable a tracer substance detected in the produced fluid to identify the set of tracer particles from which it has come and hence identify the location from which it has come. The process may be used in conjunction with hydraulic fracturing, placing sets of particles at different locations within a fracture and/or in different fractures extending from a single wellbore.
    • 对井眼穿透的地下储层进行观测的过程使用可区分的示踪剂颗粒组,并且包括以下步骤:(i)经由井孔将多组示踪剂颗粒递送到相应的地下位置,每组中的颗粒包括 跟踪物质,其区别于其他集合; (ii)当所述颗粒在相应的地下位置时,导致或允许示踪物质从示踪剂颗粒流出; (iii)导致或允许通过井筒从所述储存器中产生流体; 和(iv)检测产生的流体中示踪物质的存在或不存在。 示踪剂物质彼此充分区分,以使在所产生的流体中检测到的示踪物质能够识别来自其​​的示踪剂颗粒组,并因此识别出来的位置。 该方法可以与水力压裂结合使用,将一组颗粒放置在裂缝内的不同位置和/或从单个井眼延伸的不同裂缝中。
