Explains the production measurements, in terms of both hardware and procedures that can be used to allocate the gas and condensate back to the individual concessions, reservoirs and wells in a fair and equitable way.

This Technical Report describes the production measurements, in terms of both hardware and procedures, that can be used to allocate the gas and condensate back to the individual concessions, reservoirs and wells in a fair and equitable way. The objective is to give an approach that is recognized to be current best practice and that has a wide support in the oil and gas industry.
