At some point in their life most reservoirs will produce water. Most of this water is beneficial and helps production of oil and gas. But we also produce much water that is excessive and harmful to production.
The course objective is to offer participants a comprehensive discussion of the different sources of produced water and causes of excessive water production. It covers the mechanics of oil, gas, and water flow in the reservoir and the relationship between well completion, reservoir fluid properties, and, formation heterogeneity with water production. It offers techniques for shutting-off early water break-through, reducing coning water flow, and controlling water encroachment due to formation heterogeneity. The course includes a comprehensive discussion of the types of materials, tools, and services available in the industry, details of their application in actual operations, and their benefits and limitations. For each type of solution the course offers case studies and details of successful application.

The course also presents some of the novel mechanical tools which are available for downhole water control.

Who Should Attend :This workshop is designed for anyone who needs to reduce excessive water production from the reservoir. The emphasis is on operational aspects of the subject, with ample case histories to highlight successful treatments.
