How does Oil Drilling Work?

Oil is one of the most important resource today, with nearly every industry worldwide relying on a very significant part on oil products to operate. To supply this nearly-unlimited demand, petroleum companies turn to drilling oil from deep within the earth’s crust, and they do this in large part by installing oil rigs complete with parts like drawworks and drills in the middle of the world’s seas.

Locating Oil

The first part in this equation of course is to look for oil, and petroleum companies do this with the help of oil geologists who examine surface rocks and terrain. There are other techniques used as well, such as measuring tiny changes in the earth’s gravitational field that just might indicate the presence of flowing oil.

Preparing the Rig

Next the oil company prepares to set up shop. They consider potential environmental hazards, obtain licenses, and right-of way access. They will clear the area, dig a reserve pit to dispose of waste materials and by-products, and line the work area with plastic to protect the environment.

Operations

The crew will set up the rig and then begin operations. They dig a starter hole and position the drill bit, collar, and pipe down into the hole, attach the kelley and turntable. With everything ready, drilling can begin. As the process progresses, mud and other waste are removed and transported into the reserve pit.
