WELL TEST SYSTEM AWT-01

System features

• Measurement of well parameters, oil reserve, best exploiting mode supported well procesing
• Automatic data recording and processing in the well test. This is successfully replaced for the old method with data writing and manual process
• Real-time recording ranges from 0.1sec to 10 hours
• High accuracy in data measurement and processing, highly data safety
• Multi-model processing in the well test
• Easy-to-use functions and report printing,
• User-friendly and convenient design with all equipment and devices contained in a container

Measurement of surface parameter

The AWT-01 performs measurement of well surface in the line with downhole temperature and pressure. Surface parameters consist of: surface pressure & temperature, atmospheric pressure & temperature, separator pressure & temperature, fluid level, fluid flow.

• 24 hours operation
• Open system, easy for future extension
• Alarm indicator

Data measurement and processing software

This is composed of several functional programs:

• Kuster program: data recording set-up, data reading for downhole pressure gauge
• GlogWT program: measurement, calculation, display of recorded data in form, chart, instant clock and data printing
• GeditWT program: display of last recorded data, manual correction/entry of new data, data
• Flow calculation
• Editdata program: data adjustment, change and printing in different formats (ASCII, DBF, LAS, MRG, DBASE)
• Welltest program: well data sending/receiving, report printing
