I don't blame you for being a little bamboozled. The RNS's are a little difficult to follow. I too can't figure out what happened to t 5 so I went through all the RNS's. Here is my report for you Sir.
OCT 14
The Vertical section on T-5 was completed and it produced 100bopd unstimulated.
This was plugged and cemented and the Hz section commenced,
Pretty clear so far
FEB 3
The Hz section on T-5 is completed, with a 300m section , and it came online producing 600 Bopd.
No confusion so far.
March 20
We are informed the T-5 well is down to 400 Bopd. But due to a ESP pump failure the rig was being taken down, and a new pump was to be fitted, this could take some time to sort.
We are told that more Tungolskoye drilling would begin in early May, rather vague and no well numbers given, more of a note to say the contractors had been appointed,
May 22.
No mention of the T-5 and its pump problems. No mention at all in fact.
Howeverm we are informed of a Vertical well No, T-51b is being drilled on the south west of the field. As promised.
clear so far,
July 22
A well T-503, to be honest I was not even aware it was being drilled, was anyone else? anyhow T-503 hit oil and was brought online at 550 Bopd and later this increased to 675 bopd.
T-51b, was completed and proved disappointing, it is non commercial but can be used as a water injector.
T-508. we are informed a new well is underway, T-508.
Still no word to the original T-5 well that was awaiting the fixed pump to bring it back to life and the 400 Bopd. what has happened ? At this time I wondered could T-503 be the name for the T-5 well's Horizontal section. I doubt it, but the fact we were never told. In any case, T-5 horizontal was at 400bopd and T-503 was at 550 bopd. unless they increased the pipe length from 300m to 1000m ? Hardly?
I think it is fair to say that T-5 currently not mentioned in any recent RNS's is not T-503.
August 12
T-503 is still producing, at 500 BoPd.
T.508 was completed and with regret it was water filled. It can be used as water injector.
T.502. Is underway we are informed.
T.5 There is still no update on this well. It is possible it came back into production and we simply we not informed.
Conclusion
I am guessing that T-5 came back into production AND we were not informed of it, because management were concentrating on bringing news of new wells etc.
Or, it is simply still out of action.
Maybe a trawl back through the RNSs will reveal a clue via the Bopd total production figures,
