COURSE OVERVIEW:

Chemical Treatment for Wellbore, Wells, and Flowlines is a comprehensive program designed to address the operational challenges that occur from the reservoir face to the primary separation unit. As hydrocarbons travel through the production system, changes in temperature and pressure often trigger the precipitation of solids and the acceleration of corrosive mechanisms. This course provides participants with the technical knowledge to design and implement effective chemical injection strategies that protect assets and ensure uninterrupted production.

The scope of this course includes the management of wellbore stability, the prevention of downhole scale and paraffin buildup, and the protection of long-distance flowlines from internal degradation. Participants will examine the various delivery methods for chemicals, including continuous injection via capillary strings, batch treatments, and "squeeze" applications. The curriculum emphasizes the synergy between chemical treatment and mechanical solutions, helping engineers determine the most cost-effective approach for maintaining flow assurance across the entire production network.

Coverage also extends to the specific challenges of offshore and subsea environments, where chemical delivery is complicated by extreme distances and low temperatures. Attendees will learn how to troubleshoot injection system failures, monitor the residual concentration of chemicals in the produced stream, and adjust dosage rates in response to changing water cuts or fluid compositions. By focusing on a holistic treatment philosophy, the course empowers participants to extend the run-life of downhole equipment and maximize the uptime of critical flowlines.

COURSE OBJECTIVES:

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

• Identify the primary locations of chemical deposition and corrosion in the production system.
• Select appropriate chemical agents for wellbore cleanup and stimulation.
• Design downhole scale inhibitor squeeze treatments and calculate displacement volumes.
• Optimize the continuous injection of corrosion inhibitors in high-velocity wells.
• Implement paraffin and asphaltene control programs for flowlines.
• Evaluate the effectiveness of H2S and O2 scavengers in the well stream.
• Distinguish between different chemical delivery systems including gas lift injection.
• Diagnose and remediate common injection pump and capillary string failures.
• Monitor treatment performance through fluid analysis and coupon monitoring.
• Analyze the impact of flow regimes on the distribution of chemical inhibitors.
• Manage the environmental risks associated with chemical spills or overboard discharge.
• Adjust chemical dosages based on changing production rates and water-to-oil ratios.
• Develop a proactive maintenance plan for chemical injection infrastructure.

TARGET AUDIENCE:

Production Engineers, Flow Assurance Specialists, Well Intervention Engineers, and Field Supervisors responsible for production operations and asset integrity.

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.
