well as in conventional wells. A remotely operated plug is the only
option for this kind of well and the remotely operated TDP has worked
for all these applications.

2. Perform tubing test
3. Cycle open TDP with pressure cycling.

Additional info/comments from operator:
**All the plugs we have run have been broken with spear, which has
been the planned primary opening method. Out of 13 wells run with
TDPs for Talisman in Norway, there were some issues on one well on
Gyda due to debris on top of the plug, however at the end we managed to
break the plug with the spear. You will expect approximately 30-40 good
down jars with the slick line spear to break the glass for a 4 ½” plug, but
also this will vary some with plug setting dept and inclination.
On another well on Varg there were some challenges with the breaking
due to spear centralizing for the 7” plug, but also on this well we
managed to break the plug with the slick line spear as planned. The tool
string used for breaking the 7” TDP has now been optimized for more
efficient glass breaking.
The benefit with the glass plug is that you always manage to break it at
the end. Unlike a stubborn bridge plug which in worst case can give you
a “junked well”.
TDP plug run below the production packer. Run in TTRD wells as well as in conventional new wells.
Simplified Completion Sequence:
1. Run TDP in lower string, closed end below production packer.

Additional info/comments from operator:
*Big improvement of cycle open performance since
the setup with annulus activated triggers were utilized.
(not used in early stage). Big time saving for these
costly deepwater operations.
The big downside with the alternative ball or sleeve
plug systems are that the removal of these steel plugs
are really difficult and time consuming once they fail
to open, which has been the case in the past.
TDP plug run in tail pipe of upper completion below the auto filling sub, Single cycle tool, below the
production packer.
Simplified Completion Sequence:
1. Run TDP2 i middle completion with perforated joint above plug.

Additional info:
No access to plug in case of failure of opening with pressure
cycling. The plug has no limitations due to time frame for
finalizing lateral well as could be the case for a timer based
plug.
TDP plug run as a barrier plug in the mother bore below the whip stock.
Simplified Completion Sequence:
1. Run TDP in a piece of 7" tubing below a packer in the 9 5/8" casing prior to setting of the whip stock
2. Set packer against TDP
3. Run whip stock above TDP
4. Drill sidetrack lateral well.
5. Perforate Whip stock and complete lateral well with Diacs completion.
6. Open up sleeve to mother bore
7. Cycle open glass plug allowing production from the mother bore as well as the zones in the new
sidetrack

Additional info: The use of the auto filling tool that can be
closed by well pressure this completion method removes the
need for running a intermediate completion. The whole
completion program is without need for work over riser.
The use of this system setup has saved us many days for the
costly floating platforms on these wells.
