In the last lesson, we learned about Rig Contracts, the Rig Crew, and Different Drilling Rigs. In this lesson, we will continue our discussions of the drilling rig and start a discussion on the drilling process. In Lesson 8, we saw that there are different onshore and offshore drilling rigs. While these rigs have different applications and there are pros and cons for each, there are many similarities. We will continue our discussion on drilling rigs with these similarities.
