Jetting to Nudge 16" Hole

09 December 2008 We are drilling platform development wells offhsore Brazil and
surface anti-collision is critical in some wells. There is a
proposal to jet/nudge the top hole on the next slot where the well
path passes a exisitng producer at ~315m. The plan is to run one
large and three smaller nozzles in a 16" bit and pump at high rate
whilst sliding after orienting the nozzle. Has anyone had
experience of this and what are the learning's/pit-falls? Obviously
we are concerned with generating very high dogleg and/or failing to
nudge the well away from the existing producer and ultimately losing
the slot.
Thnaks for the input.
