Structural and Stress Analysis of a High Temperature Geothermal Wellhead
High temperature geothermal wellheads have to be designed to withstand very high pressure and temperature loads. The complex geometry of wellhead equipment make it difficult to analyze it structurally using conventional methods. In this project a finite element model of a geothermal wellhead was developed and tested using realistic load data from measurements of a well while charging. This model incorporates nonlinear material properties, taking into account the decreasing of strength with temperature, as well as yielding in the gaskets in the flange connection.
