planned Total Depth of 5,300 meters, initially targeting the same pre-salt carbonates that were successfully identified in the Deep Well A5 at depths of 4,342 meters but with a prime target being the deeper carbonate of the Devonian to Mississippian ages towards the planned Total Depth of 5,300 meters.
We identified intervals of interest at depths of 4,342 meters. We then had to decide whether to seek to produce from the intervals identified or whether to continue to the original Total Depth of 5,300 meters. The arguments in favour of seeking to produce from the higher interval were short term commercial considerations of expected significant immediate income. The arguments for continuing to the original Total Depth were based on the far greater potential from intervals in the Devonian.
While we favour pressing on to the original Total Depth of 5,300 meters a final decision is yet to be taken. As with Deep Well A6 above the planned acid treatment at Deep Well A8 has been delayed.
Deep Well A9
The next deep well on the Airshagyl structure will be Deep Well A9, which, if successful, would extend the perimeter of the Airshagyl structure. The well has a planned Total Depth of 5,300 meters and will target the same Jurassic prospects as A5 & A6.
Our intention was to spud Deep Well A9 in the first half of 2020. However, we have delayed drilling the well pending greater certainty on the lasting impact of the Covid-19 virus.
