CPC G01F 1/8436 (2013.01) [G01F 1/74 (2013.01); G01F 1/8468 (2013.01)] | 19 Claims |
1. A net oil and gas skid for use characterizing the output from one or more petroleum wells, the net oil and gas skid comprising:
a vibratable flowtube configured for receiving a multiphase fluid from said one or more petroleum wells;
a driver configured to vibrate the flowtube;
a pair of sensors configured to detect movement of the flowtube at different locations on the flowtube and output sensor signals indicative of the detected movement;
a temperature sensor configured to measure a temperature of the multiphase fluid;
a pressure sensor configured to measure a pressure of the multiphase fluid;
a water cut meter adapted to measure relative amounts of oil and water in the multiphase fluid; and
one or more processors configured to receive the sensor signals, determine a phase difference between the sensor signals, and use the determined phase difference to determine a fluid flow rate through the flowtube, wherein said one or more processors are further configured to:
receive a signal from the water cut meter indicative of relative amounts of oil and water in the multiphase fluid;
determine a density of the multiphase fluid in the flowtube using the sensor signals; and
determine an amount of dissolved gas in the multiphase fluid using the temperature and pressure of the multiphase fluid.
