Description

INTRODUCTION
The select tester valve is a kind of downhole tester valve in oil and gas well testing operation. The select tester valve is the Halliburton type tester valve, which is composed with ball Valve section, upper hydraulic section, nitrogen section and the metering section. The select tester valve is featured with a full bore design and operated by the annulus pressure. This kind of downhole tester valve has the capabilities of taking multiple downhole closures where pipe manipulation is restricted and a full opening string is desired
