Oil drilling involves several key steps. First, a drilling rig is set up at the selected site, where a hole is bored into the earth's crust using a drill bit. As the drill penetrates deeper, drilling mud is circulated to cool the bit, stabilize the well, and transport rock cuttings to the surface. Once oil is reached, it is extracted through the well, often aided by pumps or natural pressure from the reservoir.
