RE: Surface Casing.30 Nov 2024 21:41
Not complicated at all. If they set the surface casing at 15 degrees, Kick off and drill at 10 degrees per 1000 feet or so and then set the next casing at 50 degrees. I do not have the programme so all a rough guide. Then drill out the float and shoe drill a few hundred feet at 50 degrees and then pull the drilling assembly. Pick up the coring assembly and start coring at 50 degrees. Simple enough.
