BAGGI BA-2PS
2 Phase Well Test Separator
The SensEvolution BAGGI BA-2PS is part of the BAGGI BASE®
Instruments Series.
These instruments are the result of combining the latest state-of-the-arttechnology with over 50 years of industry experience.
It is a skid mounted two phase (total liquid + gas) well test separator,
equipped with all the necessary valves, measurement devices and an
embedded computer. The skid is easily truck transportable.
The watercut is determined by applying a high frequency electromagnetic
signal to the liquid phase and measuring the related absorption and
frequency shift. This technique allows using a 2-phase separator, instead
of a 3-phase instrument, for providing reliable and accurate data in well
testing applications. The above electromagnetic probe is complemented
by Coriolis mass flow meters.
The advantages offered by a 2-phase separator are listed hereafter:
Smaller vessel size
Reduced retention time: no need to separate oil from water
Reduced purging time: small liquid volume
Better accuracy: watercut is measured 0 - 100% in the single liquid leg
Reduced number of flow meters and valves
Less piping and maintenance
The figure beneath gives an overview of the system:
Two probes (of the type described above) are in charge of determining the level of the gas/liquid
interface. Their output signals are collected by the embedded computer (BASE® Series), which is able to
control the dump valve. In addition, the computer collects the readings from the watercut monitor probe,
the flow meter in the liquid outlet pipe and the flow meter in the gas
outlet pipe.
The application software, by comparing the readings from the
electromagnetic watercut monitor with the readings from the Coriolis
densitometer/flowmeter, is able to perform an accurate self-diagnosis.
