Sidetracking Guidelines

Sidetracking Guidelines

Wells may require sidetracking in order to re-drill the well to a new target, sidetrack past a fish or sidetrack due to hole problems.

The main requirements in sidetracking a well is the development of a lateral force to allow the bit to cut on the side of the hole. This lateral force should be provided by the geometry of the BHA forcing the cut on the side of the hole.

The most effective BHA configuration to achieve a successful sidetrack kick off is a mudmotor with bent sub.
