Drilling concepts
What happens when drilling a oil well?
To drill an oil well a drilling rig is obtained and a drill bit is attached to a length of pipe, once the length of pipe is in the hole another length of pipe is added and that drilled down etc.. While drilling the well normally a fluid is pumped around the system for various reasons
