Drill test

To determine the potential of a producing formation, the operator may order a drill stem test (DST). The DST crew makes up the test tool on the bottom of the drill stem, then lowers it to the bottom of the hole. Weight is applied to the tool to expand a hard rubber sealer called a packer. Opening the tool ports allows the formation pressure to be tested. This process enables workers to determine whether the well can be produced.

Potential Hazards:

* Being pinched or struck by the drill stem test tools during floor operations.

* Swabbing the hole on the way out with the test tool could cause a kick to occur, which could result in a blowout leading to injuries and deaths.

* Being exposed to unexpected release of H2S or other gases or liquids.

* A packer seat failure or fluid loss to an upper formation could cause a kick that might result in a blowout causing injuries and deaths.

* Other hazards are similar to those encountered during trippingout/in.

Possible Solutions:

* Wear appropriate PPE.

* Instruct workers in handling and using the special tools required during drill stem testing.

* Keep a method for filling the hole in place at all times. Before any test starts, the rig management must ensure that the blow-out prevention system includes a kill system that is capable of pumping fluid into the well below the annular preventer and at least on-set of pipe rams.

* Run a pump-out-sub or downhole circulating device in the test string to to enable the system to be reversed.

* Ensure all workers on the location understand the dangers before starting any drill stem test. They should be fully informed of and trained in appropriate safety procedures, including the use of safety equipment and breathing apparatus. If in an H2S area, post a sign indicating the test in full view for the general public to see. Post reliable people to stop them from coming to the location. Define a minimum of two muster points with all vehicles parked in an appointed area.




Now for my thoughts

This is a guess only

I believe they have tested Pinkerton and Alkali and during this they lost part of the DST tool so had to either start all over again or move up, replace the tool and continue.

While down there they thought well instead of finishing and releasing any limited info we have,lets close off Pinkerton and Alkali and lets replace or get the tool, move up and now test Barker then we will come back up to release any results for Barker and will do the other 2 later...................sounds feasible but is just my guess at this stage.

Alternatively they have tested Pinkerton, then Alkali, lost the tool on the way to Barker, have been held up to replace the so called lost tool, therefore everything has been slowed down, Barker is being tested and results for just Barker or all 3 will be analysed and told to the market shortly.

I really are confusing myself now
