Quasi-static study on the fluid and structure interactions of the subsurface safety valves (SSSV) for extreme high pressure and high temperature (XHPHT) applications
This thesis summarizes the preliminary design work of a new subsurface safety valve (SSSV) for extreme high pressure (30,000 psi) and high temperature (450°F) (XHPHT) applications. Current SSSV designs are not reliable ...
An approach for efficient analysis of drill-string random vibrations
Lateral vibrations are widely recognized as the leading cause of drill-string failures in oil well operations. The finite elements method formulation is used for the mathematical modelling. Due to the erratic nature of the ...
A computational analysis on an initial application of a Hemiwedge based sub-surface safety valve for use in ultra-deepwater oil wells and extreme high pressure, high temperature environments
This study proposes and validates computationally the effectiveness of a novel, hemiwedge model for a sub-surface safety valve (SSSV). With the growing needs in the oil industry and new finds of ultra-deepwater reservoirs ...
