About the course

For every barrel of oil produced we produce 3 barrels of water. Water handling, treatment and disposal represent the biggest operating cost for most oilfield operators. In addition to produced water, large quantities of seawater and water from other sources is treated and injected. 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 tolls used for testing, diagnosing, and minimizing water production from oil and gas wells. Reservoir engineering and surface facility aspects of water handling, treatment, re-injection and injection well fracturing are extensively discussed. The impact of the growth of thermal fractures and fractures driven by particle plugging on injector performance and oil recovery by water flood 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 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:

  • Specify water quality requirements for a water injection project
