  • Well Modeling Associated With Extraction of Hydrocarbons From Subsurface Formations
    Publication number: 20100299111
    Abstract: A method and apparatus for producing hydrocarbons is described. In the method, a failure mode for a well completion is identified. A numerical engineering model to describe an event that results in the failure mode is constructed. The numerical engineering model is converted into a response surface. Then, the response surface is associated with a user tool configured to provide the response surface for analysis of another well.
