Liquid gold is a commodity that is also known as oil. Due to animal waste and plant decomposition under high temperature, oil is formed under the earth’s crust. It is used for a variety of different things and the most common use the automobile. Different types of oil drilling tools and equipment are used to drill out the oil from beneath the earth’s crust. Whenever oil is taken from the earth, a hole will be dug in the Earth’s crust. Because the crust is not same or uniform, it has many different types of boulders and rocks. This means the path of hole digging is not always constant. Using a stabilizer is a tool that is set up near the drill collar in order to change or maintain the drilling angle. Another tool that is used in the oil drilling is the drill collar. This tool is a heavy thick walled tube that is attached to the drilling pipe and it is designed to keep it under tension.
