🔍 Key Concepts

• Types of drill bits used in offshore drilling and what each is designed to do • How core samples are taken from the seabed or formations • The difference between a bit that removes all material vs. one that leaves a solid center section

💭 Think About

• Which type of bit would be most useful if you want to study the exact material in the center of the hole being drilled? • Think about which term is associated with taking a sample (or "plug") of rock or soil rather than just creating a full‑diameter hole. • Which option names a tool that enlarges or redirects a hole, instead of collecting a center portion?

✅ Before You Answer

• Match the term that specifically relates to sampling the center material of the hole. • Eliminate any answer that mainly describes enlarging a hole or directing flow rather than sampling. • Ask: Which option name have you seen used with geological or formation sampling in drilling contexts?
