COURSE OVERVIEW:

The Chemical Nature of Oilfield Chemicals and Compatibility course is a technical exploration into the molecular structures and interactions of the diverse chemical agents used in oil and gas production. As the industry moves toward more complex reservoirs and enhanced recovery techniques, the variety of chemicals introduced into the wellbore has increased exponentially. This course provides a scientific foundation for understanding how these substances work and, more importantly, how they react with each other and the indigenous reservoir fluids.

The scope of this program focuses on the functional chemistry of inhibitors, surfactants, demulsifiers, and biocides. Participants will examine the organic and inorganic pathways through which these chemicals operate, gaining insight into the mechanisms of surface adsorption, film formation, and micelle behavior. A critical component of the course is the study of chemical compatibility, which addresses the risk of forming harmful precipitates, emulsions, or "gunk" when incompatible treatments are mixed in the wellbore or surface facilities.

Coverage includes the laboratory methodologies used to screen chemicals for performance and safety. Attendees will learn how to design compatibility tests that simulate downhole temperatures and pressures to prevent operational failures. By understanding the chemical nature of these products, engineers and chemists will be better equipped to manage complex chemical injection programs, optimize dosage rates, and protect both the asset integrity and the environment from the unintended consequences of chemical interference.

COURSE OBJECTIVES:

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

• Classify oilfield chemicals based on their molecular structure and functional groups.
• Explain the physical chemistry of surfactants and their role in emulsion management.
• Describe the chemical mechanisms of corrosion and scale inhibitors.
• Evaluate the solubility profiles of various chemicals in water and hydrocarbon phases.
• Identify the risks associated with mixing anionic, cationic, and non-ionic surfactants.
• Analyze the impact of pH and salinity on the effectiveness of chemical treatments.
• Perform compatibility screenings between different chemical products.
• Predict the formation of precipitates resulting from chemical interactions.
• Assess the thermal stability of chemicals in high-temperature environments.
• Describe the chemistry of biocides and their interaction with organic matter.
• Interpret Material Safety Data Sheets (MSDS) to understand chemical reactivity.
• Optimize multi-chemical injection sequences to prevent interference.
• Design laboratory protocols for qualifying new chemical formulations.

TARGET AUDIENCE:

Production Chemists, Chemical Engineers, Laboratory Analysts, Flow Assurance Engineers, and Technical Personnel responsible for chemical management.

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.
