Book Description

Petroleum reservoir management practices are rooted in the optimization of costs and benefits specific to reservoirs with respect to their location, geology, reservoir properties, operational activities, and economic considerations. This book covers important reservoir management topics that engage the attention of petroleum companies over the life cycle of an oilfield.  Further, project management issues such as inadequate definition of the projects, periodic changes in the project description/scope and inordinate delays in project completion, are described. It also brings discussion on the crude oil markets, instruments, pricing mechanisms, criteria, and strategies into its ambit.


  • Exclusive title on petroleum reservoirs management including actual field performance data and experience.
  • Reviews sub-surface and surface management issues.
  • Discusses project and price management critical to oil industry.
  • Describes macro management issues covering the reservoir life cycle from production to pricing.
  • Includes role of teamwork, open communication, and synergy in reservoir management.

The book aims at professionals and graduate students in petroleum and reservoir engineering, oil and gas companies, and environmental engineering.
