Zusammenfassung:	A method of assessing flow from an individual well in a set of oil and gas wells includes flowing output from a first subset of the wells collectively to a first flow measurement system through a first conduit while flowing output from a second subset of the wells collectively to a second flow measurement system through a second conduit different from the first conduit. Total flow through the first flow measurement system and total flow through the second measurement system are measured. Output from said individual well is rerouted from one of said first and second measurement systems to the other of said first and second measurement systems. Total flow through at least one of the first and second measurement systems is measured after the re-routing. A difference between the total flow rate before the re-routing and after the re-routing is used to assess flow rate from said individual well.
