COURSE OVERVIEW:

Miscible gas injection is a premier Enhanced Oil Recovery (EOR) technique used to significantly increase recovery factors by eliminating the interfacial tension between the injected gas and the reservoir oil. This course provides an advanced technical foundation in the design, implementation, and monitoring of miscible injection projects. Participants will explore the thermodynamics of phase behavior and the mechanisms of multi-contact miscibility, including vaporizing and condensing drives.

The design phase of a miscible gas project requires precise characterization of the Minimum Miscibility Pressure (MMP) and the selection of an appropriate injection gas, such as carbon dioxide, nitrogen, or enriched hydrocarbon gas. This course covers the laboratory testing procedures and compositional modeling required to ensure miscible conditions are maintained throughout the reservoir. Attendees will also learn about the design of Water-Alternating-Gas (WAG) schemes to improve sweep efficiency and manage gas mobility challenges.

Surveillance and troubleshooting are critical for the success of miscible EOR projects, which are often sensitive to reservoir heterogeneity. This curriculum details the tools and techniques for tracking the gas front, managing early breakthrough, and assessing the efficiency of the injection process. Participants will gain practical insights into the operational challenges of handling high-pressure gas and managing the corrosion risks associated with CO2 and sour gas injection, ensuring a safe and economically viable EOR operation.

COURSE OBJECTIVES:

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

• Explain the fundamental mechanisms of miscible vs. immiscible gas injection.
• Define and determine the Minimum Miscibility Pressure (MMP) using laboratory data.
• Analyze ternary diagrams to understand multi-contact miscibility processes.
• Select the optimal injection gas based on reservoir temperature and oil composition.
• Design a Water-Alternating-Gas (WAG) program for mobility control.
• Utilize compositional reservoir simulation to predict EOR performance.
• Assess the impact of reservoir heterogeneity on gas fingering and channeling.
• Implement surveillance techniques to monitor the movement of the miscible bank.
• Diagnose and mitigate premature gas breakthrough in production wells.
• Evaluate the economics and incremental recovery of miscible gas projects.
• Manage the operational risks of gas injection, including hydrate and corrosion control.
• Interpret gas tracer test results to evaluate inter-well connectivity.
• Formulate a long term field development plan for a miscible EOR project.

TARGET AUDIENCE:

This course is designed for Reservoir Engineers, EOR Specialists, Production Engineers, and Project Managers focused on secondary and tertiary recovery methods.

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.
