Ann: Lockyer Deep-1 Operational Update, page-332

I was doing some rough calculations.
With the 9 5\8 inch casing having an ID of 226.6 mm.
The drill would need to fit through, say 215 mm for dia of annulus.
Its 1177 meters from the 9 5\8 casing to the TD.
With the 5 1\2 inch producing casing having an ID of 125.7
That would need 36 cubic meters of cement to fill the annulus up to the 9 5\8 casing.
And if they did use 36 cubes the 5 \15 production casing would be filled to approx 1324 meters below the surface
Could that be correct???
And I guess that the drill crew got it to the milling well before the cement had time to cure. So maybe not too hard.
Sorry about the inches and millimeters thing...lol
