Scenario: You are an engineer working on a subsea oil and gas production project. The field contains multiple horizontal wells, and the team is considering using EXHT TM instead of traditional subsea trees.
Task:
**Two Key Factors:** 1. **Reservoir Characteristics:** The flow rate and pressure characteristics of the horizontal wells are crucial. If the wells are expected to have high flow rates and pressures, EXHT TM would be a more suitable choice due to its enhanced flow capacity and reduced pressure drop. 2. **Field Development Plan:** The overall development plan, including the number of wells, well spacing, and production strategy, should be considered. EXHT TM's modular design and flexibility could be advantageous for complex field layouts. **Potential Benefits:** * **Increased Production:** The higher flow capacity and reduced pressure drop of EXHT TM would lead to increased production volumes from each well. * **Reduced Operating Costs:** Improved efficiency and reduced pressure drop can result in lower operating expenses over the lifetime of the wells. * **Extended Well Life:** The robust design of EXHT TM can contribute to longer well life, maximizing the economic potential of the field. **Potential Drawbacks:** * **Higher Initial Costs:** EXHT TM may have a higher initial investment compared to traditional subsea trees. * **Limited Industry Experience:** EXHT TM is a relatively new technology, and there may be less industry experience and data available compared to traditional systems. **Conclusion:** The decision to use EXHT TM should be carefully evaluated based on the specific reservoir characteristics, field development plan, and the potential benefits and drawbacks outlined above.
