• Please describe directional drilling.
• Where can you find most higher-grade ores?
• What does ‘holding’ mean?
• Compare the size of holes drilled in copper versus the size of holes drilled in petroleum.
• What are 3 different examples of processes used in a transportation system. Then explain what ‘marketing’ is and why it is an important part of the transportation system.
- Directional drilling involves drilling a wellbore that does not go straight down, but instead curves and follows a specific path to reach a desired location underground. This technique is commonly used in oil and gas exploration, as well as in some mining operations.
- Higher-grade ores are typically found in concentrated deposits in specific geological formations. Some locations where these ores are commonly found include deep underground in mineral veins, in sedimentary rock formations, and around volcanic areas.
- 'Holding' in drilling refers to the process of stabilizing or supporting the drill string and tools during drilling to prevent them from shifting or moving unexpectedly. This is done by using a stabilizer or support structure to keep the drill string in place.
- The size of holes drilled in copper mining is typically smaller compared to the size of holes drilled in petroleum extraction. This is because copper deposits are more localized and compact, while petroleum deposits are spread out in porous rock formations that require larger wells for extraction.
- Examples of processes used in a transportation system include routing and scheduling, traffic management, and vehicle maintenance. 'Marketing' in transportation refers to strategies and activities aimed at promoting transportation services to potential customers. It is important in the transportation system as it helps attract customers, generate revenue, and compete effectively in the market.
