If we did not drill for oil in the first place
we would never get to the stage of gasoline manufacture. Many
persons wonder how it is accomplished. The following content
details the fundamental steps of drilling for oil.
1. First a drill bit, collar and drill pipe are placed in the hole
where the drilling is to take place.
2. Next a turning device is attached and the process of drilling
3. Mud is circulated through the pipe and exits the bit in order to
4. New pipes are added as the hole becomes deeper.
5. The pipe is removed as well as the collar and bit when a
predetermined depth is reached: this can be anywhere from several
hundred feet to two thousand feet.
6. The casing pipe is placed in the hole in order that the hole
will not cave in. It is subsequently cemented.
7. The drilling process is one that is continual until oil is
reached. This means casings or casing pipes are installed within
the hole and afterwards cemented and once again drilling resumes.
When rock from the outflow of mud shows oil the final depth has
8. A perforating gun is placed inside the well. The gun employs
charges (explosive in nature) that will allow oil to flow through
holes inside the casing.
9. Next a small pipe is placed in the hole in order that the oil
may flow upwards.
10. A device referred to as a packer is placed on the outside of
the pipes and forms a seal.
11. A multiple valve is set on top of the pipes and is cemented to
the top. The multiple valve also known as a “Christmas Tree” allows
for proper control of oil flow from the well.
