Drilling Rigs

Forfatter:
Engelsk
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.
