3 IntroductionThe 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.
4 AVT-II Capabilities Test any valve at pressures to 3000 psig Save, print, or post test results to networkCan test 3 valves simultaneouslyUses very little nitrogenSelect any convenient units of measureRequires very little trainingMuch more accurate and consistent than manual testing
5 AVT-II Software Features Perpetual software license with purchaseStations can be run individually or simultaneouslyOnce valve is loaded, performs a complete set of tests in less than 20 seconds.Calibration routine for each test stationStores data from each test in spreadsheet formatTest screen shows real time pressure trace of each station as test is conductedUser inputs Pass/Fail criteria
7 AVT-II Hardware Features Components are highest quality…Sensotec transducers +/-.1% accuracyHigh reliability solenoidsData Acquisition system by National InstrumentsAll stainless steel fittings and manifoldRated to 3000 psig working pressure
8 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.
9 Business Justification Use the AVT-II to qualify valves during setup in the gaslift workshopUse 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 gaugesSafe and easy to use. Does not require an experienced gaslift shop technician
10 Business Justification Print a certificate showing…Ptro, Pvct, R ratio, Port leak rate, Stem travel, and loadrateDate of test, Valve type, and serial numberReliableField ProvenMuch more thorough testing of valve than current gaslift shop practices
11 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-usedAdded assurance that the valves sent to the field will perform as engineer anticipates.Better gaslift performance and less wireline work.
