To become a driller-trainee, you need to go through a training program that lasts for about four weeks. You will learn about how to use the equipment and how to read maps. You will also learn about safety precautions and emergency response procedures. The company I work for has a training program that teaches people how to become a driller-trainee in four weeks.
