SNAP™ Exercise

Scenario:

You are an engineer working on a new oil pipeline project. The pipeline will transport oil from a remote well to a processing facility located 100km away. The pipeline has a diameter of 1m and will carry a flow rate of 1000 barrels per day. You need to use SNAP™ to determine the optimal pump size for the pipeline to ensure efficient and safe oil transport.

Task:

Using the information provided above, outline the steps you would take to use SNAP™ to determine the optimal pump size for the pipeline.

Exercise Correction

Here's a potential approach using SNAP™:

Create a Network Model:
- Define the pipeline geometry (length, diameter, roughness) and the well and processing facility nodes within SNAP™.
- Specify the flow rate and fluid properties (oil density, viscosity).
Simulate Pipeline Flow:
- Utilize SNAP™'s pipeline flow simulation capabilities to model the flow through the 100km pipeline.
- This will provide data on pressure drops and flow characteristics along the pipeline.
Determine Pump Requirements:
- Based on the simulated pressure drop, determine the minimum pressure required at the pump outlet to overcome the pipeline resistance.
- Use SNAP™'s pump modeling features to simulate different pump sizes and characteristics.
- Analyze the pump output pressure and flow rate to find the best match for your pipeline requirements.
Consider Safety Margins:
- Add safety margins to the pump's capacity to account for fluctuations in flow rate, pipeline friction, and potential future modifications.
Optimize Pump Selection:
- Iterate on pump models, considering factors like energy efficiency, cost, and availability.
- SNAP™'s analysis tools can help you evaluate different pump options and select the most suitable one.

By following these steps, you can leverage SNAP™'s capabilities to determine the optimal pump size for your oil pipeline project, ensuring efficient and safe oil transport.
