Oilfield Multi Cycle Tester Valve for DST operation
Multi Cycle Tester Valve / Select tester valve Full H2S Service
Introduction of Downhole tester valve
The Multi Cycle Tester valve is the full bore tester Valve applied in Drill stem testing operation. The multi cycle tester valve also name select tester vavle is an annulus pressure controlled ball valve and designed to allow multiple cycles during cased hole testing and perforating operations. The ball valve operates independently of pressure changes from operations such as acidizing and fracturing. This gives the Select Tester valve greater compatibility and flexibility with other tools in the string.
Features and Benefits
• Incorporates advanced materials and processes providing a unique metal-to-metal seal for exceptional gas-holding capabilities
• Has undergone extensive five-day qualification testing at 400°F and 15,000 psi including a 16,500 psi burst and collapse test
• Allows operator to reverse out/circulate to the lowest point of circulation below the Select Tester valve. This facilitates well kill operations, saving both time and money.
• Allows operator to run in or come out of a hole in the open position, enhancing safety and maximizing well control options
• Allows operator to spot cushion to the lowest point of circulation below the Select Tester valve. This improves control of drawdown pressure and reduces recovery of mud and other rathole fluids.
• Simplifies string design by eliminating the need for a bypass when stinging into or out of a production packer
• Maximizes flexibility during well kill operations since the Select Tester valve can be operated with the packer unset.
