Injection Well; Theory and Practice
A 2-day Course

March 6-7, 2014
Bakersfield, CA, USA

Course Description:

Worldwide, on a daily basis, thousands of wellbores are used for injection of carbon dioxide, gas, water, steam, and other fluids deep into different geological zones of interest. On the first day of this course, injection well design and fluid mechanics of injected fluid in the well tubing and near wellbore zone are presented. Of particular interest is the relationship between fluid flow rate and pressure, specifically in the injected strata. The fluid injectivity is constrained by plugging (positive skin factor) and induced fractures (negative skin factor). For assessment, Hall, Hearn, Theis, pressure superposition methods, and area of review are presented. In day two, injection well testing and interpretation as relate to obtaining values of skin factor, injectivity index, and reservoir pressure are discussed. Finally, an introduction to BOAST Black-Oil Simulator, available through the Department of Energy, will be presented.

Course Level:

This course is an intermediate level course.

Who Should Attend?

This course is intended for the following audience:

  • Geologists
  • Reservoir engineers
  • Environmental engineers
  • Production engineers
  • Personnel involved with carbon dioxide injection, waterflooding, steam injection, and disposal well operation


Dr. Mason M. Medizade - President and CEO, Petrolects, LLC

Dr. Mason Medizade has more than twenty five years of experience in the oil and gas industry, worldwide. His oilfield experience spans from reservoir engineering, drilling, and completion, to enhanced oil recovery and petroleum production. Specifically, he has done engineering work related to real time production monitoring, production enhancement, drilling fluids, reserve estimation, filtration, sand control, surface facility design, and EOR and reservoir management. He has been involved in consulting, research and teaching in renewable and non-renewable energy sources since 1984. Dr. Medizade's recent oilfield work involves real time flow monitoring for which he has obtained a US patent. Dr. Medizade is president and CEO of Petrolects, LLC.

Dr. Medizade is also a faculty member in the mechanical engineering department at California Polytechnic State University in San Luis Obispo, where he focuses on petroleum engineering, wind energy, thermodynamics, and fluid mechanics. Professor Medizade has taught numerous short courses in petroleum engineering to clients such as Petroleum Development of Oman (PDO), California Division of Oil and Gas, Petroleum Technology Transfer Council (PTTC), Texaco, Pertamina, and others. Dr. Medizade is an active member of the Society of Petroleum Engineers (SPE) and many other professional societies. He has authored numerous technical papers. His recent SPE paper discusses cyclic steam injection monitoring in diatomite. He has won numerous awards and certificates for his teaching and research work, including professorship from UNOCAL. He holds Ph.D. and M.S. degrees in petroleum engineering from University of Southern California (USC), and a B.Sc. degree in chemical engineering from Abadan Institute of Technology (AIT) in Abadan, Iran.
