摘要： A net oil and gas well test system for a set of oil and gas wells includes at least two net oil and gas measurement systems and a plurality of valves that are in fluid communication with the individual wells in the set and independently configurable between a first state, in which the valve routes flow to a first net oil and gas measurement system, and a second state, in which the valve routes flow to a second net oil and gas measurement system. Each net oil and gas measurement system suitably has the capability to measure a multiphase flow including oil, gas, and water without separation. For example, each measurement system can include a multiphase Coriolis meter and a water cut meter. Each measurement system suitably includes the capability to provide dynamic uncertainty estimates related to measurement of the multiphase flow.
