Modern Aspects of Chemical EOR

Introduction

Enhanced Oil Recovery is usually conducted when a reservoir has shown a decline in productivity and Chemical EOR is one of the tertiary methods required to improve the oil & gas recovery. Proper management and process of Chemical EOR will withdraw excessive oil in the reservoir and increase the production of oil.

Our Modern Aspects of Chemical EOR course is developed to provide comprehensive coverage of all chemical EOR processes. The course materials are based on the instructor’s hands-on experience and personal collection of field cases and learning.

Course Design Focuses on Practical Applications

This course focuses on practical aspects and applications of Chemical EOR as well as the significant theories behind it.

Includes Specific and Practical Case Studies

This course covers a lot of case studies based on the instructor’s personal collection of field cases, especially from Chinese field practices where chemical EOR projects are mostly done. Quizzes and calculation exercises are included. You will also learn how to manage the real Chemical EOR process by undergoing a closely guided hands-on simulation practice for Chemical EOR using the UTCHEM software.

Objectives

• Develop Best Fit of Synergies in Chemical EOR
  Develop Best Fit of Synergies in Chemical EOR by learning each EOR mechanism and the combined EOR methods.
• Identify the Key Parameters and Data Range of Each Chemical Process
  Able to identify the key parameters and data range by practical learning through examples of field projects.
• Gain Non-Academic Knowledge of Chemical EOR
  Gain the knowledge which is not available from academic studies by learning from real personal experiences and field studies from Dr. James.
• Improve Oil Recovery in Oil Production Stage
  Improve oil recovery by learning to design, optimize and carry out simulation practice of Chemical EOR Project
• Manage Real Chemical EOR Process
  Attain best practices in Chemical EOR processes through managing real Chemical EOR Process by understanding and learning Chemical EOR Simulation using UTCHEM software.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

The course is designed for professionals who want to know comprehensively how the best practice in implementing chemical EOR projects is:-

• Reservoir engineers
• Petroleum Engineers
• Chemist/Laboratory technicians
• Geologist
• Project engineers
• Project coordinators
• Project managers

Course Outline

DAY 1 & DAY 2:

Day 1 begins with concepts about EOR such as incremental recovery and salinity. These are brief concepts to understand and select EOR methods.
Day 1 and Day 2 continue with polymer flooding. The key parameters of polymer flooding are polymer viscosity to improve mobility ratio, and permeability reduction to improve injection profile. Special cases will be discussed.

• Introduction to Chemical EOR
• Polymer Flooding

DAY 3:

Day 3 covers the chemical EOR process – surfactant flooding. To carry out a field project, we need to know what lab tests we need to do; we need to understand the parameters which are related to the reduction of residual oil saturation such as capillary number, IFT, and capillary desaturation curve.

• Surfactant Flooding

DAY 4:

Day 4 first covers alkaline reactions, followed by combined methods. We focus on the important aspects of combined methods: their interactions and synergies. We will address some important questions such as why single alkaline flooding may not work well, why polymer is always needed.

• Alkaline Flooding
• Alkaline-Surfactant-Polymer Flooding
• Screening Criteria for Chemical EOR Processes
• Special Issues from Course Participants

DAY 5:

Day 5 summarizes the advantages and disadvantages of each method and combined methods and focuses on the problems with ASP which are much less discussed in the literature. We will discuss some practical issues and answer the questions from the attendees which will give the attendees an opportunity to make the best use of this course.

• Alkaline-Surfactant-Polymer Flooding
• Screening Criteria for Chemical EOR Processes
• Special Issues from Course Participants
