Description:A drilling rig is a complex piece of machinery designed for a single purpose — to drill oil, gas or geothermal wells. The drill string primarily consists of drill pipe, each length about thirty feet long and ranging in diameter from as small as two and seven-eighths inches to as large as seven and five-eighths inches. Drill collars are similar to drill pipe, but with thicker walls, which greatly increase pipe weight. The increased weight is designed to improve drilling performance and provide stiffness to prevent buckling and undesired deviations from the planned wellbore.
