The Turkey announcement was 23 July 2020.
It wasn't a co-incidence that they were still suggesting HH-2z could be salvaged as a producer in June and the first OGA (as it was then) monthly production figures with significant water cuts were soon to be published - 9% water cut in May, released early September and 24% water cut in June released early October.
From the 30 June 2020 Interim Report (ie when UKOG already knew HH-1 was producing 24% water) about HH-2z:-
'A number of options are being reviewed for the future use of HH-2z, including stimulation to return it into long-term production, sidetracking the well to a different subsurface location and possibly converting it into a future water re-injection well to implement pressure support and further reduce future operating costs (as foreseen in the Horse Hill FDP)'
as for HH-1 in June (when UKOG knew the water cut was averaging 24%) things were all hunky dory apparently, this also from the interim report:-
'Post period a higher capacity and energy efficient linear rod pump was installed on HH-1, leading to increased production from the Portland interval. As of 29 June 2020, 113,143 bbl in total has been produced from Horse Hill'
Except the average daily production was dropping fast - April (first month 'post period') 243bopd, May 177bopd plus 18bwpd, June 158bopd plus 49bwpd.
The only other 'news' about HH-1 was this:-
Post-period, the Company also plans a significant intervention in HH-1 specifically designed to further improve flow into the wellbore. Together with a full reperforation of the entire Portland section using a different type of perforating gun than prior operations, a new , simpler production tubing completion will be installed. The new completion will permit the downhole pump to be installed below the Portland interval to significantly improve pump efficiency.'
Which lead to speculation that the reperforation of the whole section would improve production massively, and the deeper pump might be in the Kimmeridge - both BS.
On 16 July UKOG announced the completion of buying the PW production kit - I posted (remember still not knowing about the water ingress at HH-1):-
'The main issue though is that by buying this kit UKOG are admitting that this is the production set up at HH for quite a long time.'
