The disclosure features methods of analyzing a fluid extracted from a reservoir, the methods including introducing a first composition featuring a first complexing agent into a reservoir at a first location, extracting a fluid from the reservoir at a second location different from the first location, combining the fluid with a second composition featuring a concentration of a lanthanide ion to form a third composition featuring a concentration of a complex formed by the first complexing agent and the lanthanide ion, exposing a quantity of the complex to electromagnetic radiation for a first time period ending at a time t0, detecting fluorescence emission from the quantity of the complex for a second time period starting at a time t1>t0, where t1−t0 is greater than 2 microseconds, and determining information about a fluid flow path between the first location and the second location.
本公开的特征是分析从储层中提取的流体的方法,该方法包括在第一位置将具有第一络合剂的第一组合物引入储层,在不同于第一位置的第二位置从储层中提取流体,将流体与具有镧系离子浓度的第二组合物结合以形成具有由第一络合剂和镧系离子形成的络合物浓度的第三组合物、将一定量的络合物暴露于电磁辐射中,第一时间段结束于时间 t0,检测一定量的络合物在第二时间段的荧光发射,第二时间段开始于时间 t1>t0,其中 t1-t0 大于 2 微秒,确定第一位置和第二位置之间的流体流动路径信息。
