Which of the following statements is/are CORRECT about the water injection well platforms?
Show Hint
Think about what an injection platform actually injects, and what safety and metering equipment any offshore platform must carry.
Updated On: Aug 17, 2026
- These are meant for injection of gas through the injection well.
- Metering devices are not required to determine injection rate of injection wells.
- Metering devices are required to determine injection rate of injection wells.
- Firefighting and life-saving equipment should be present on the platform.

The Correct Option is C, D
Solution and Explanation
Step 1: Understand the purpose of a water injection well platform:
A water injection well platform is an offshore facility built to inject water into the producing reservoir, mainly for pressure maintenance and secondary recovery through waterflooding. This is a different function from a gas injection platform, which is built to handle and inject gas rather than water.
Step 2: Analyze option (A):
Option (A) claims the platform is meant for injection of gas through the injection well. Since a water injection platform is specifically designed for water handling and injection, not gas, this statement is incorrect.
Step 3: Analyze options (B) and (C):
Options (B) and (C) make opposite claims about metering devices. On an injection platform, flow meters and other metering devices are essential because the injection rate into each well must be measured and controlled to manage reservoir pressure support, sweep efficiency, and to satisfy regulatory reporting requirements. So option (C), stating that metering devices are required, is correct, while option (B), stating they are not required, is incorrect.
Step 4: Analyze option (D):
Option (D) states that firefighting and life saving equipment should be present on the platform. Every offshore platform, whether it is a production platform or an injection platform, must carry firefighting systems, lifeboats, life jackets and other safety equipment as required by offshore safety codes. This makes option (D) correct.
Step 5: Combine the findings:
Option (A) is false, option (B) is false, option (C) is true, and option (D) is true. So the correct statements are (C) and (D).
Final Answer:
\[ \boxed{\text{(C) and (D) are correct}} \]
