There are five basic steps to drilling the surface hole:
- Place the drill bit, collar and drill pipe in the hole.
- Attach the kelly and turntable and begin drilling.
- As drilling progresses, circulate mud through the pipe and out of the bit to float the rock cuttings out of the hole.
- Add new sections (joints) of drill pipes as the hole gets deeper.
- Remove (trip out) the drill pipe, collar and bit when the pre-set depth (anywhere from a few hundred to a couple-thousand feet) is reached.
This of course is how to drill for oil... ; ) |
