1. A system for identifying and quantifying a fluid in a gas-oil separation plant conduit, comprising:
a first wellhead and a second wellhead;
a first flowline coupled to and downstream of the first wellhead and a second flowline coupled to and downstream of the second wellhead;
a first prospector spool apparatus coupled to the first flowline and downstream of the first wellhead and a second prospector spool apparatus coupled to the second flowline and downstream of the second wellhead, the first prospector spool apparatus and the second prospector spool apparatus each comprising:
a housing including an inlet end and an outlet end;
an inlet coupled to the housing and positioned at the inlet end;
an outlet coupled to the housing and positioned at the outlet end;
a porous layer comprising a polymer media and a prospector molecule embedded therein, the porous layer being positioned within the housing between the inlet end and the outlet end, an inner surface of the porous layer defining a flow channel therethrough configured to allow fluid flow;
wherein the prospector molecule has a chemical affinity for fluid selected from the group consisting of oil, gas, and water, and is configured to diffuse into the fluid flow; and
wherein the prospector molecule of the first prospector apparatus is different than the prospector molecule of the second prospector apparatus;
a header coupled to and downstream of the first flowline and the second flowline configured to receive and commingle fluid from each of the first and second prospector spool apparatus outlets;
a collection point downstream of the header configured to collect a sample of the commingled fluid.
