First up, like a lot of other poster here, I'm no geo or well engineer, far from it. But .....

....... another thought just occurred to me about 76H - in the event that 77H does connect through to the 76H fracced and stimulated region, due to the problems experience at 76H it only was able to flow back initial fracc fluids over several days, the majority was never retrieved and is still in place.

In which case, if Oilex does manage to connect through to 76H they might have to deal with several consequential issues:
1. Firstly, additional fracc fluids recovered, above the volumes pumped into 77H, will be a sign of connection
2. Possible prolonged flow back of 76H fracc fluids travelling a significant distance along the horizontal fracc zones from the furthest reaches of 76 - possibly >700m
3. Possible interference with oil/condensate flows from 77H by the prolonged flow back from 76H  
4. Pressure of approximately 1200psi was reached at 76H wellhead which may also come into play - if 77H is greater than 1200psi then 76H may drain some of 77H's pressure - and vice versa 76H may pump up 77H and create more overpressure.

All up a potentially more complex set of circumstances to deal with that could affect the timings (delays), flow back and operation of 77H at this clean up stage (viz the work carried out since 21/7).  Again I'm no well engineer, but I imagine these circumstances may also affect things like the operation of the well toe, pressure seals and maybe the fracc tree.  

Now there has been no word about this at any stage leading into and post 77H. Possibly the whole idea was dropped and not pursued for technical/other reasons, there may also be specific commercial in-confidence reasons for an embargo.  

76H Background: involved an 8 stage fracture stimulation program of the Eocene “tight” reservoir Y Zone. It had a 610m horizontal section and all 8 fracture stimulation stages were successfully executed and milled
