Introduction of DST Hydrospring Tester
The Hydro spring tester was a reliable and field-proven downhole
master valve which is used in open hole drill stem testing
operation.. The hydro spring tester is a combination tester valve
and bypas and
operated by vertical movement of the drillpipe, the weight of the pipe effectively opens the tester and sets the packer. Raising the drill pipe closes the tester.
Specification of DST Hydrospring Tester

Features of DST Hydrospring Tester
- The hydrospring is opened easily by slacking off drill pipe weight
- When the hydrospring tester opens, it will give an indication at the surface
- Fewer assembilies required to combine the tester valve and bypass.
Operation of DST Hydrospring Tester
When positioning the tester valve for opening, it will record
initial hydrostatic mud weight clearly on the pressure chart during
the time interval . The hydrospring tester with an indexing J-slot,
does not have a built-in bypass. If bypass is desired, the LOC
bypass can be used. Repeated opening and closing of the tester
valve for closed-in and flow periods is done by reciprocating the
pipe. The indexing J-slot will automatically index so when every
alternative time weight is set down, the tester valve will remain
closed
