Flagging in Oil & Gas: Exercise

Instructions: You are working on a drilling rig. The drill pipe sections are flagged with different colors to indicate their depth:

• Red: 0-1000 feet
• Blue: 1001-2000 feet
• Green: 2001-3000 feet

You need to connect three sections of pipe:

• Section 1: Green flag
• Section 2: Red flag
• Section 3: Blue flag

Problem: What is the correct order to connect these sections to ensure the deepest section is at the bottom?
