about Multiphase Flowmeters
About the Watercut Meter study
Our focus on flow
has recently been on the emerging development of multiphase
flowmeter technologies. Developments here are of particular value in the oil
& gas industry, an industry that we routinely report on as part of our
world view of measurement applications. In Module A, we take a closer view of
watercut meters, which have been a mainstay within the oil and gas industries
The demand for better accuracy in the measurement of this critical ratio has been driven by three primary factors: 1) the need to have reliable data to effectively manage each well; 2) the need for predictive information to plan for secondary recovery investments; and, 3) the emergence of and growth in new field drilling techniques such as directional drilling and line pooling.
The three drivers cited above all exist within the context of an increase in more difficult offshore and subsea exploration & production, as well as the new plays in shale/sand oil and gas production. Today’s depressed oil and gas prices – while not likely a long term concern – are evidence of the market volatility and economic peril that well operators will encounter in the short and medium terms.
And, in addition to user demands for improved product performance, watercut meter manufacturers are also beginning to see the encroachment of alternative technologies such as multiphase flowmeters. Multiphase flowmeters have held the promise of reducing the total number of components an operator needs to properly evaluate wellhead flows, and are closer than ever to fulfilling that promise.

applications measure one type of flow, either liquid, gas, or steam.
This is called single phase flow measurement.
However, a need has now developed to measure fluids with more than
one phase. This measurement is
of multiphase flow, and it primarily occurs in the oil & gas industry.
fluid initially comes out of a well, it often consists of a mixture of oil,
gas, and water. While these
different fluids are typically separated into their individual components
at separators near the wellhead, it is also sometime advantageous to
measure the fluid before it is separated.
A group of flowmeters have been developed to do this, and they are
called multiphase flowmeters.
flowmeters are used for multiple purposes, including custody transfer, well
testing, and allocation metering. One disadvantage of these meters is that
they are extremely expensive, so they tend to be used mainly on high
producing wells. Not all wells
produce enough oil or natural gas to justify the expense of a multiphase
meter. While there are still a
limited number of suppliers, this is an area that bears watching,
especially considering the high price of oil and the continually expanding
search for sources of energy.

with both the Gas Flow and Oil Flow studies, the Multiphase study is now
independent. To read about multiphase in the previous oil study, click this
