The newest development in portable well testing is the MiniGauge.
The MiniGauge – was developed to quickly and accurately measure produced fluids in low volume wells. The MiniGauge is setup with small and short piping for fast to sampler action and sensor-less gross and water cut measurements. Gross production is measured by direct sight-glass observation in a pressurized vessel, whereas the water cut is obtained by a direct to test tube iso-kinetic automatic fluid sampler.
MiniGauges are available to test 0-30 b/d and 10-100 b/d gross fluid producers.
MiniGauge results look just like regular Dynogauges with strip charts of gross, net, and dyno pump displacements.
