About the course
For every barrel of oil produced we produce 5 barrels of water. Water handling, treatment and disposal represent the biggest operating cost for most oilfield operators. In many unconventional gas plays, frac water and produced water needs to be recycled to conserve groundwater and minimize subsurface injection. 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. It particularly emphasizes field application through lots of practical field examples, exercises and case studies.
Designed For
Reservoir, production, completion and surface facilities engineers responsible for providing reservoir engineering support, facilities planning and drilling and fracturing recommendations for oil and gas assets, engineers and other personnel involved in providing equipment and chemicals for diagnosing / reducing water production, improving injector performance and treating produced water.
