Introudction Select tester valve
The select tester valve is a kind of main downhole tester valve improved from the LPR- N valve, it is the lock open tester valve with a full opening design and operated by annulus pressure which is used in cased holes DST operation.
The select tester valve includes four main sections: ball valve section, nitrogen section, upper hydraulic section and the metering section.

Operating the Downhole Tester Valve With Multi-cycle Circulating Valve
During cased hole drill stem testing operation, when using a Multi-cycle Circulating Valve in connection with the downhole select tester valve, the major area of concern is the operating pressure. The Select Tester Valve uses an operating pressure that is significantly lower than what has been used in the past to operate the standard LPR-N or Multi-cycle Circulating Valve.
Under optimum conditions the operating pressure for the Select Tester Valve should be enough to operate the Multi-cycle Circulating Valve. If the conditions are less than ideal and you need to use a higher operating pressure to cycle the Multi-cycle Circulating Valve, it must be applied in stages to prevent premature operation of the "lock open" feature of the Select Tester Valve. It is recommended that when applying pressure in excess of the "normal" operating pressure of the Select Tester Valve that:
SELECT is in the "Normal Mode"
1. Apply normal operating pressure + 300 psi max. on the initial pressure increase. Any additional pressure must be applied in stages.
2. Wait 5 minutes.
3. Apply additional pressure in stages of 100 psi per minute.
SELECT is in the "Locked Open Mode".
1. Apply the operating pressure+400psi max. On the initial pressure increase, any additional pressure must be applied in stages.
2. Wait 5 minutes
3. Apply additional pressure in stages of 100 psi per minutes.
