- W2307171092 abstract "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 and M University, has developed a procedure to design long drillstrings quickly and consistently. Suspending long drillstrings with additional loads creates structural concerns for both the drillstring and the derrick. Vessel roll and current loads induce bending stresses in the drillstring. Predicting peak drillstring stresses and derrick loads is time consuming and error prone. The program, called Drillstring, performs a complete, error-free analysis in second whereas the same analysis would require hours to complete by hand. Furthermore, the program has two optimization subroutines, one to maximize overpull capacity and another to maximize the overall safety factor. The paper discusses background of the ODP, drilling equipment, structural concerns, payloads, stress, optimization, dynamics, and overpull." @default.
