rayz old chappie,

i for one have said nothing to suggest info other than formal reports or common oil patch knowledge.
by the way, you say "Im sure we do not want a twister[ head of drill] down hole and loaded with break downs". to be helpful, to my understanding a twister is either of
1. a tornado
2. someone who dances to a chubby checker song or
3. a person of doubtful reputation.
a bottom hole drill assembly in contrast consists of a drill bit of whatever choice, a series of stabilisers and more often than not these days a down hole MWD tool.
of course under certain unfortunate circumstances the string may become stuck or even twist off, but that is something quite different. in this case i suspect that the deepening was due to the formations encountered being off prognosis. again i hasten to add that this is simply my reading of events, and does not constitute any special information. there are other possibilities as well. as i said before, i do not see this issue as being of any critical significance. after all, if the top hole is drilled deeper, then the bottom hole has less to drill, and possibly with a far more expensive rig.
trust this informative.
