Automated Validation Tester
II
Decker Technology, Inc
AVT-II
Introduction
The AVT-II is an automated validation
tester for any type gaslift valve.
 A computer directs the AVT-II to test
opening and closing pressure, effective
stem travel, loadrate, port leak rate,
and R ratio.
 A Pass/Fail indicator shows the status of
all tests.

AVT-II Capabilities







Test any valve at pressures to 3000 psig
Save, print, or post test results to network
Can test 3 valves simultaneously
Uses very little nitrogen
Select any convenient units of measure
Requires very little training
Much more accurate and consistent than
manual testing
AVT-II Software Features







Perpetual software license with purchase
Stations can be run individually or simultaneously
Once valve is loaded, performs a complete set of tests in
less than 20 seconds.
Calibration routine for each test station
Stores data from each test in spreadsheet format
Test screen shows real time pressure trace of each
station as test is conducted
User inputs Pass/Fail criteria

AVT-II Hardware Features

Components are highest quality…
– Sensotec transducers +/-.1% accuracy
– High reliability solenoids
– Data Acquisition system by National
Instruments
– All stainless steel fittings and manifold
– Rated to 3000 psig working pressure
AVT-II Hardware Features




Small desktop footprint (15x18 inches)
Changing valves is quick and easy. About 2
minutes.
Run over 3000 tests on a single bottle of
nitrogen (New nitrogen bottle at 2500 psig
and valve set at Pvct = 1275 psig)
Change valves in one station while other
stations continue to test.
Business Justification




Use the AVT-II to qualify valves during setup
in the gaslift workshop
Use the AVT-II to test valves returned from
the field. Build a data base of valve use.
Testing is consistent and more accurate than
analog gauges
Safe and easy to use. Does not require an
experienced gaslift shop technician
Business Justification

Print a certificate showing…
– Ptro, Pvct, R ratio, Port leak rate, Stem travel, and
loadrate
– Date of test, Valve type, and serial number



Reliable
Field Proven
Much more thorough testing of valve than
current gaslift shop practices
Business Justification




Reduce the number of wireline re-entries due
to failed or under performing valves (field
proven in Oman!)
Maintain a database of the number of times a
valve has been re-used
Added assurance that the valves sent to the
field will perform as engineer anticipates.
Better gaslift performance and less wireline
work.
