General Guidelines for Sidetracking

General Guidelines for Sidetracking

The main requirement in sidetracking a well is the development of a lateral force to allow the bit to cut on the side of the hole.

BHA Geometry

The required lateral force shall be provided by the geometry of the BHA. The most effective BHA configuration to achieve a successful sidetrack kick-off is a mud motor with bent housing.

Kick-off Point Selection

If possible, the kick-off location shall be selected where a soft or soft-medium formation is present to increase the chances of obtaining a successful kick . . .
