COMPUTER ANALYSIS IMPROVES DEEPWATER DRILLSTRING DESIGN
Matthew J. Stahl Texas A&M University-Ocean Drilling Program College Station, Tex. A method for quickly calculating critical drillstring loads and the stresses produced by axial loads and bending helps determine optimum drillstring configuration. The Ocean Drilling Program (ODP), operated by Texas A&M University, has developed a procedure to design long drillstrings quickly and consistently. Such extremely long, complex drillstrings are used in deepwater drilling operations.
