Exercise: LPSA in Production

Scenario: You are working as an engineer at an oil production facility. You have been tasked with monitoring the size of sand particles in the produced fluids to ensure efficient oil flow and prevent damage to equipment.

Task: Using your knowledge of LPSA, outline a plan to monitor sand particle size in the produced fluids. Consider the following:

• Sample collection: Where and how will you collect samples?
• Analysis procedure: How will you use LPSA to analyze the samples?
• Data interpretation: What information will you look for in the LPSA results?
• Action plan: What actions will you take based on the results?

Example:

• Sample Collection: Collect samples from the flowline at regular intervals.
• Analysis Procedure: Use LPSA to analyze the collected samples and determine the size distribution of sand particles.
• Data Interpretation: Look for any significant increases in the proportion of larger sand particles, which may indicate a potential risk of equipment damage.
• Action Plan: If significant increases in larger sand particles are detected, adjust production parameters or implement sand control measures to mitigate the risk.
