One of the major challenges associated with the exploration and production of unconventional gas is how they manage significant volumes of flowback and produced water. Water management have a crucial role to play in successful developments of unconventional gas. The economic success of oil and gas development projects depends very much on our ability to successfully manage water.

This course discusses methods, equipment and tools used for testing, diagnosing, and minimizing water production from unconventional oil and gas wells. Reservoir engineering and surface facility aspects of water handling, treatment, re-injection and injection well fracturing are extensively discussed. New technologies which allow beneficial re-use of produced water/frac water are presented. The impact of the growth of thermal fractures and fractures driven by particle plugging on injector performance are discussed. Significant cost savings can be achieved in all aspects of water production, handling and disposal through better diagnostic tools, better water handling and better treatment, reuse and re-injection strategies. The course covers the fundamental theory, and the latest technological developments.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Use new technologies which allow beneficial re-use of produced water/frac water
  • Evaluate basic regulations governing use/re-use of fresh/produced water
  • Manage the risks of unconventional gas E&P Activities
  • Specify water quality requirements for a water injection/fracturing project
  • Simulate the impact of water quality on injector/fracturing performance
  • Make facilities decisions to ensure good long-term well injectivity/disposal
  • Conduct diagnosis of water production problems
  • Identify potential sources of water for injection/fracturing
  • Dispose produced water on surface and under what conditions
  • Select possible remediation methods for water shutoff in oil reservoirs
  • Test injection wells to identify injection profiles
  • Simulate the impact of solids and thermal effects on injection well performance
