Multistage Completions, Fracturing, and Refracturing in Shales


Disciplines: Completions, Production and Operations

Course Description

This course gives an overview for completing, fracturing, and refracturing shales and other low-permeability formations that require multistage hydraulic fracturing. Participants will learn the primary types of wellbore completion options, plug-and-perf, ball-activated systems, and coiled tubing-activated systems, and how they compare in different applications. Participants will also learn hydraulic fracturing and refracturing theory and design, including slick-water fracturing, cross-linked gels, fluids, proppants, additives, refracturing options, and identifying refracturing candidates.

Topics:

  • Multistage completion options
    • Plug-and-perf completions
    • Ball-activated completion systems
    • Coiled-tubing-activated completion systems
  • Benefits and considerations for each completion option
  • Application comparison of completion options
  • General fracturing theory and design
  • Selection of fracturing components – fluids, proppants, etc.
  • Fracturing challenges – proppant transport, conductivity, fracture geometry, etc.
  • Stimulation Design Optimization – stage placement, risk mitigation
  • Refracturing theory and challenges
  • Identifying refracturing candidates
  • Refracturing options and design considerations

Upon completion of this course, participants will be able to:

  • Identify the different types of multistage completions
  • Recognize the benefits and considerations for each type of completion system
  • Use knowledge gained to select completion based on their specific application
  • Understand theory and design of fracturing and refracturing wells
  • Compare the application specific challenges for a fracturing and refracturing job
  • Apply knowledge gained to their fracturing and refracturing application

Why Attend

In the last decade new production from shales and other low-permeability reservoirs that require multistage hydraulic fracturing has significantly influenced the price and supply of hydrocarbons. The success of these plays in North America has operators around the globe trying to identify similar reservoirs. In order to replicate these results in new plays and implement a more sustainable and improved approach to unconventional resource development in existing plays, it is important to understand and recognize the multiple options and challenges of completing, fracturing, and refracturing these types of wells.

Who Attends

This course is designed for all Oil and Gas Industry professionals involved in planning, drilling, completing, hydraulic fracturing, asset management, and operating wells with multistage hydraulic fracturing.

Instructors

Sergey Kotov Sergey Kotov is a Global Manager of Integrated Well Intervention Solutions for Baker Hughes. He holds an M.S. in Petroleum Engineering from the North Caucasus State Technical University, in Stavropol Russia. He is also an Honors graduate of the State Linguistic University in Pyatigorsk, Russia, with a M.A. in Linguistics. His 25 years professional experience includes technology development, design and wellsite implementation in conventional and unconventional well completion/stimulation projects in the USA, Russia, Canada, Saudi Arabia, United Arab Emirates, Algeria, Libya, China, Mexico, Australia, New Zealand, Argentina, and Colombia.

W. Aaron Burton’s career has been focused on the completion of shales and similar unconventional plays that require multistage hydraulic fracturing. In 2015, Burton started Unconventional Oil and Gas Training, a company specializing in training and consulting for unconventional multistage completions. Prior to starting the company, he was with Baker Hughes for nearly 8 years. During his tenure in operations he held the roles of field engineer, operations coordinator, and application engineer. Outside of operations he has been Product Line Strategist, Completions Manager for the Unconventional Resource Team, and Product Line Manager for unconventional multistage completions. He has completed wells, conducted training, and consulted on a variety of projects worldwide. Through his experience, he has developed a solid understanding of reservoir properties and stimulation design that are used in a data-driven approach to more effectively design completions in unconventional wells.

He is active in the industry authoring and instructing on the subject of unconventional completions. He has authored and coauthored three SPE papers, and continues to teach two SPE continuing education courses. He has written a variety of other documents including magazine articles and newsletters, and taught numerous classes in many different venues to operators, service companies, and other companies involved in the industry. Also, he has been a discussion leader, presenter, panelist, and participated in many other roles in industry events.

Burton holds a BS in mechanical engineering from Mississippi State University
