... Abstract This paper proposes a methodology (1) to estimate the contact forces generated by the drillstring against the wellbore and the marine drilling riser system. A new procedure for overall analysis of the drill string behavior inside the riser and wellbore is described...

... of the mooring lines favors a system of individual wellheads on the seafloor. Wells can be drilled, completed, and produced without pulling the drilling riser. When production from the field reaches its economic limit, the entire system can be towed to a new location and reused. cellar deck guide frame...
