System Approach to Chemical Injection System Design

Production and Operations


Oil and gas production challenges have increased significantly with deeper waters and newer technologies.

Flow assurance challenges and fluid separation issues have cast a significant demand on production chemicals to a point that the latter has become an integral part of production operations.

A multitude of various facets have to come together for a successful chemical injection program. These various elements bring a variety of issues by themselves, but the industry itself lacks a ‘systems approach’ to chemical injection system design and operation.

The design of the chemical system should be done right the first time so that operational nightmares are avoided.

This course details the various elemental aspects of the chemical injection system from design of the system including tankage, pumping, monitoring, delivery and optimization to chemical portfolio management from manufacture to delivery including product quality, contamination avoidance, rate control monitoring, inter-chemical impacts etc. As a graduate of the course, the trainee will be able to understand the total chemical injection package and all of the steps that should be followed to ensure that effectively selected specialty chemicals are used in clean operating environments and are delivered using a robust and established injection system based on good design to the right injection locations at the right dosage rates.

After the course, you will:

  • Be able to understand production chemical testing and the various considerations including functional requirements, compatibility, effectiveness and shelf life.
  • Requirements for good design of the various aspects of the chemical injection system including storage tanks, pumps, dampeners, piping, metallurgy, injection system, valving, flow control valves etc.
  • Various aspects typically overlooked in chemical injection system design.
  • Good commissioning practices to ensure proper system handover to operations.
  • Monitoring and optimization of the system.
  • General troubleshooting.
  • Case histories.
