''As previously announced our plan to bring Deep Well 801 into production was by drilling a side track of between 450 – 500 meters from a starting depth of 4,501 meters.
Having identified potential oil bearing (net-pay) intervals covering in aggregate 121 meters so far during the drilling of the side-track, we have decided to stop the side-track at a depth of 4,851 meters and, after running and cementing a 5-inch liner to the full depth of the side-track, to test the well.
Four potentially oil bearing intervals have been identified during drilling and supported by mud log data. The first of 6 meters between 4,535 and 4,541 meters; the second is of 20 meters between 4,554 and 4,694 meters; the third is of 59 meters meters between 4,635 and 4,694 and the fourth is of 36 meters between 4,812 and 4,848 meters.
The pressure in Well 801 remains high indicating good connectivity. As the side-track has been drilled using lower density drilling mud we expect the task of getting the well to flow to allow testing to commence should be easier than previously drilled deep wells.''

''At Well 802 the problem has been our inability to remove a stuck pipe to allow the well to be properly tested. Work at Well 802 has now stopped to allow the rig to be used to drill Well 803 the last of the deep wells in our BNG work programme, which is due to be spudded in mid-November and drilled to a planned depth of 3,950 meters. Drilling is expected to complete by March 2024.''
I find it hard to believe the 803 Deep Well is only drilling to a depth of 3,950m when between 4,535m and 4,848m there are 4 very thick net-pay intervals (at least 121m of net-pay) deeper down as found in the 801 Deep Well, which could be connected to each other (and the 802 Deep Well) and oil bearing. Why are they not using the more powerful G70 rig to drill the 803 Deep Well deeper down, which has apparently been sat there for many months doing nothing since drilling the A8 Deep Well?
The 803 Deep Well should have spud by now.
