Learning Objectives

Upon successful completion of this course, participants will be able to:

1. Introduction to Chemical Treatment in Oilfield Operations

• Understand the role of chemical treatment in production optimization.
• Identify common wellbore, well, and flowline challenges that require chemical intervention:
• Scale formation.
• Corrosion and microbial-induced corrosion (MIC).
• Wax and asphaltene deposition.
• Emulsions and water separation issues.
• Gas hydrate formation in flowlines.

2. Chemical Treatment for Wellbore and Formation Protection

• Select effective chemical treatments for downhole applications:
• Scale inhibitors for mineral deposition prevention.
• Corrosion inhibitors to protect tubulars and wellbore equipment.
• Biocides to prevent microbial growth and souring.
• Surfactants and acidizing agents to improve formation productivity.
• Implement treatment techniques (squeeze treatments, batch injection, continuous dosing).

3. Chemical Treatment for Wells and Production Systems

• Apply demulsifiers to enhance oil-water separation.
• Use foamers and anti-foam agents in gas wells.
• Deploy paraffin and asphaltene inhibitors to prevent wax buildup.
• Optimize EOR chemical treatments for enhanced oil recovery.
• Assess chemical compatibility and formation damage risks.

4. Chemical Treatment for Pipelines and Flowlines

• Apply corrosion inhibitors for pipeline integrity protection.
• Implement scale removal and mitigation techniques.
• Select drag-reducing agents (DRA) for improved pipeline efficiency.
• Prevent hydrate formation in multiphase flowlines using kinetic inhibitors and thermodynamic suppressants.
• Perform pipeline pigging and flushing with chemical additives.

5. Chemical Treatment Optimization and Application Techniques

• Determine optimal chemical dosage and injection rates.
• Evaluate chemical placement strategies (continuous injection, batch treatment, bullheading, soaking, and squeeze treatments).
• Use real-time monitoring tools to assess chemical performance (corrosion probes, fluid analysis, downhole sensors, pipeline coupons, and PVT analysis).

6. Troubleshooting and Problem-Solving in Chemical Treatment

• Identify early signs of scaling, corrosion, and fouling issues.
• Address overdosing and underperformance of chemical treatments.
• Optimize chemical usage to reduce costs and maximize efficiency.
• Implement preventive maintenance strategies for wells and pipelines.

7. Regulatory Compliance and Environmental Considerations

• Ensure compliance with OSHA, EPA, REACH, MARPOL, OSPAR, and industry-specific chemical regulations.
• Apply biodegradable and environmentally friendly treatment solutions.
• Manage chemical waste and disposal in accordance with HSE standards.

8. Case Studies and Practical Applications

• Review real-world chemical treatment challenges and solutions.
• Participate in hands-on chemical treatment design exercises.
• Develop a customized chemical treatment program for a specific well or pipeline scenario.
