Process of Drilling

Process of Drilling Overview of t he Drilling Process A borehole is drilled by rotating a bit at the end of a drill pipe. Borehole cuttings are removed by continuous circulation of a drilling fluid as the bit penetrates the formation. The drill pipe is connected to the drill engine. Drilling fluid is pumped down through the hollow drill pipe using

Oil and Gas Drilling The Process

The depth of the well will vary by region and formation. In the Marcellus Shale the well is then drilled horizontally an average of 10,000 more feet (~3,048 meters). When the target length is achieved, “production casing” is inserted throughout the length of the wellbore. The drilling process is now complete and well stimulation can begin.

The Oil Drilling Process Explained HowStuffWorks

The process begins by drilling a hole deep into the earth. To do this, a long bit attached to a "drilling string" is used. The bit varies in diameter from five to 50 inches. After each section is drilled, a steel pipe slightly smaller than the hole diameter is dropped in and often cement is used to fill the gap.
