While we wait…
21st Aug RNS announced that the A5 side-track is underway from 3976m depth, targeting an additional 500m by the end of Sept 19, implying an expected drill rate of appx 12.2m/day (500m/41days) which has evidently not been achieved.
27 working days later, 17th Sept RNS advises that A5 is “more than 200m” deeper, and therefore somewhere below 4176m, implying an indicative average drill rate of at least c7.41m/d.
13 working days later, 30th Sept RNS advises A5 is at 4288m, implying a drill rate of c8.62m/d, at most, since the RNS on 17th. The aggregate average drill rate is now up to c7.8m/d but drilling is paused for logging.
37 working days later, 6th November RNS advises A5 is at 4324m after a further pause to widen the well bore. The pause dropped the implied drill rate since last the last RNS to c0.97m/d, bringing the aggregate average drill rate down to appx 4.52 m/d.
The same 6th Nov RNS advises a revised expected TD of 4450m i.e. 126m left to drill.
At the highest observable drill rate achieved to date, 8.62m/d, A5 might have TD’d around Wednesday afternoon-ish, assuming that drilling was still ongoing without any further pauses since the last company RNS.
At the slightly lower historical rate of 7.8m/d, A5 would have TD’d yesterday-ish after drilling its final 45cm in just under an hour and a half.
Assuming that Casp are taking their time, because they do, and using the second slowest historic aggregate drill rate, of 7.41 m/d, it would take c17.01 days from the last RNS to reach TD.
Which is today, with 3cm left to drill, which should take just under 6 mins. Ish. Rejoice!
With the final casing still left for BH to do, no surprise there’s been no A5 update since 6th November. Yet. Maybe next week. Probably the week after with the November production numbers.
At the slowest daily rate, 4.52m/d, assuming another pause, TD won’t be until 3rd December. Ish.
As for the other deeps, who knows? But rest assured Clive says it could be “this period”. The Cretaceous period - c80million years. “This period”, the Neogene - 23m years and counting! The man keeps saying he’s not technical so I’m hoping he wasn’t speaking geologically.
Good luck all. A5 Should be nearly there. Ish.
N.b. above assumes 24/7/7 drilling & that depth measurements and RNS content were produced by CC and signed off, the day before RNS publication. It also dismisses the little porkie in The Interims, that they announced the A5 side-track was underway on 2nd August. They didn’t. See 21st Aug RNS.
