Reservoir measurement in the oil & gas industry

Optimization of well production through flow data measurement

Usually a central system of large separator vessels will accept the multiphase product pipeline flows coming from separate wellheads, to produce the separate outputs as single phases of oil, gas and water, plus a slurry of sand or other solid sediments in water. The output of each valuable phase is measured, using Coriolis or ultrasonic custody transfer flowmeters, before transfer to the downstream processing plant or storage reservoirs.
