Drilling is a cutting process in which drill is used to make a hole. Drilling process usually creates rough surfaces. Therefore, reaming is done after drilling to make a good surface finish, without changing the chemical and physical properties of the material. In reaming, only 5% of the material is removed (rest is removed by drilling process done before).
what must be done to prevent this from happening
The drilling rig is a semi-submersible platform (not anchored to the sea floor). It has been destroyed by fire and is lying in 5,000 feet of water at the ocean's bottom. As it plunged into the ocean, it drifted and is a good distance (I believe around 1,400 ft) from subsea wellhead. The drilling platform will never be repaired.
This is the open pit mine. Surveys are conducted (including drilling) and mapping is done. Then, with the location of the ore bodies pinpointed, material is removed, drilling and blasting create the ore pile, and the ore is loaded and hauled to the crusher. From there is it off to the processing plant.
If you are drilling with no returns it is imperative to watch pressure, torque and hookload. Before every connection ream the pipe at least half way to make sure you are free. Connection time is imperative, any sign that pressure cannot be maintained or that the string is not free pull out of the hole until pipe is free and try to regain pressure. If TD is reached on the hole and casing is run cement tools such as a cement basket, ecp or acp will need to be figured based on estimated geological data.
cracking (and when done with a catalyst, it's called catalytic cracking)
Some oil drilling is done on rigs at sea, where there are no trees. Some oil drilling is done in countries that are primarily deserts.

4000ft
yes... spot facing can be done useing a drilling machine. for more info just download drill press text book.ppt @google cheers....
acetone soak would work..buuut the best way that i have observed is soak them in hot water and try cracking them other than that i have no clue..good luck (:
If you stop cracking your knuckles, they may eventually return to their normal state. Continued cracking can lead to joint inflammation and reduced grip strength over time, so it's best to avoid the habit to prevent long-term damage.

Hacking refers to testing and improving computer systems for security purposes, while cracking involves breaking into systems for malicious intents. Hacking is often done ethically to identify vulnerabilities and enhance security, while cracking is illegal and done to exploit weaknesses for personal gain.

There is little that can be done to prevent stupid people asking unanswerable questions.
