Beskrivning
Drilling rigs come in many sizes and do many jobs. Some machines drill thousands of feet under the ground. The biggest rigs reach distances of up to 8 miles below the surface. Readers will also learn about oil platforms—the drilling rigs of the sea. The remarkable photographs and diagrams inside this book show drilling rigs up close and demonstrate how they work.
