Drill String
A Drill String is the long chain of connected pipes used in oil and gas drilling operations to drill wells. Think of it like a very long, strong straw that connects the drilling rig at the surface to the drill bit deep underground. It's a crucial piece of equipment that allows workers to drill through earth and rock while also delivering drilling fluids and providing a way to control and steer the drilling direction. When someone mentions experience with drill strings on their resume, they're typically referring to their knowledge of managing, maintaining, or operating this essential drilling equipment.
