Analysis of a reservoir fluid using a molecular factor computational system

A method of analyzing a reservoir fluid in real-time comprising:

• providing an analyzer, wherein the analyzer is a molecular factor computational system;
• wherein the molecular factor computational system comprises a processor, an energy source, and at least two pairs of a detector and a filter;
• and
• determining at least one property of the reservoir fluid using the analyzer, wherein the step of determining comprises:
• causing or allowing energy from the energy source to interact with the reservoir fluid as the reservoir fluid is flowing;
• detecting the interaction between the energy and the reservoir fluid as it is flowing;
• and
• screening the reservoir fluid for the at least one property in real-time as it is flowing;
• wherein the molecular factor computational system further comprises a switch that directs the energy source through the at least two pairs of a detector and a filter, and wherein the method further comprises operating the switch to select the individual filters in succession to screen for at least two properties in real-time;
