COURSE OVERVIEW:

Chemical Enhanced Oil Recovery (CEOR) represents a sophisticated suite of technologies designed to recover immobile oil that remains trapped in the reservoir after primary and secondary recovery methods have been employed. This course examines the fundamental physics and chemistry of injecting specialized fluids primarily polymers, surfactants, and alkalis, to alter the mobility ratio and reduce interfacial tension. Participants will explore the molecular interactions between these chemicals, the reservoir rock, and the fluid phases to understand how microscopic displacement efficiency can be significantly improved.

The scope of this training covers the entire project lifecycle, from laboratory screening and fluid formulation to pilot design and full-field implementation. It details the mechanisms of polymer flooding for mobility control, surfactant flooding for capillary pressure reduction, and the synergistic effects of Alkaline-Surfactant-Polymer (ASP) combinations. Technical coverage includes the challenges of chemical adsorption, thermal degradation of polymers, and the impact of reservoir salinity and hardness on chemical performance.

In addition to the theoretical foundations, the course provides a practical roadmap for field application and operational management. Attendees will analyze case studies of successful and unsuccessful CEOR projects to identify best practices in facility design, chemical handling, and produced fluid treatment. The program emphasizes the economic evaluation of chemical EOR projects, striking a balance between the high upfront cost of chemicals and the long-term benefits of incremental oil production in mature assets.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Differentiate between primary, secondary, and tertiary oil recovery mechanisms.
• Describe the physical properties of EOR polymers and their rheological behavior.
• Explain the role of surfactants in reducing interfacial tension to ultra-low levels.
• Analyze the synergy of alkali in ASP flooding to reduce surfactant adsorption.
• Perform laboratory screening tests for chemical compatibility with reservoir fluids.
• Calculate the mobility ratio and its impact on volumetric sweep efficiency.
• Design a polymer rheology program tailored to specific reservoir permeability.
• Evaluate the thermal and mechanical stability of chemical additives.
• Assess the impact of water salinity on the viscosity of polymer solutions.
• Develop a chemical injection strategy including slug sizing and concentration.
• Identify the requirements for surface facilities in chemical preparation and EOR.
• Troubleshoot produced water treatment issues related to chemical breakthrough.
• Conduct a technical and economic feasibility study for a field-wide CEOR project.

TARGET AUDIENCE:

Reservoir Engineers, Production Engineers, Petroleum Geoscientists, and Chemical Engineers involved in mature field redevelopment and enhanced recovery projects.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
