Scenario: An oil company is planning to drill a new well with multiple zones that they intend to produce separately. They are considering using EZSV TM bridge plugs for the following operations:
Task: Explain how the EZSV TM bridge plug's key features make it a suitable choice for these operations. Specifically address:
**Ease of deployment:** EZSV TM's rapid deployment minimizes downtime during testing and evaluation, allowing the company to quickly isolate zones and move on to the next stage of the operation. This contributes to increased efficiency and reduced overall project time.
**Vertical orientation:** By maintaining a consistent vertical orientation, the EZSV TM ensures reliable sealing, preventing leaks and ensuring the integrity of the isolated zones. This is crucial for accurate testing and safe production from individual zones.
**Drillability:** The EZSV TM's drillability provides flexibility in well development. If adjustments are needed during production, the company can easily drill out the plug to access the isolated zone. This eliminates the need for costly interventions and allows for efficient modifications as needed. Additionally, during sidetracking operations, the company can easily drill out the EZSV TM, removing the barrier to create a new path without compromising the well's integrity.
