...] was applied. The model indicated that drillstring failures would occur across shallow doglegs mainly because of high hang-down loads combined with slow ROP. The results of the study led to the development of new deep-well design criteria and implementation of new drilling guidelines. The new guidelines...

... necessary for the second problem. Reciprocation was quickly ruled out because slack-off drag would severely restrict casing return to bottom, and the risk of lost returns caused by surge pressures would be high. Alternatively, rotation was chosen. This paper discusses the design and rotation of a 3,409-ft...
