b) It allows for greater flexibility and accuracy.
5. How does proper perforating depth control contribute to well performance?
a) By reducing the risk of perforating non-productive zones. b) By increasing the lifespan of the well. c) By optimizing hydrocarbon production. d) All of the above.
d) All of the above.
Scenario: A well is being completed in a reservoir with multiple productive zones at different depths. The target zone for perforation is located between 10,000 feet and 10,100 feet. The wellbore pressure is 5,000 psi.
Task: Explain which depth control method would be most suitable for this scenario and why. Describe the steps involved in using this method to ensure the perforating gun is fired at the desired depth.
In this scenario, **electronic depth control** would be the most suitable method. Here's why:
**Steps Involved:**
By using electronic depth control, the perforations can be placed precisely within the desired target zone, optimizing hydrocarbon production and minimizing risks associated with incorrect perforation placement.
