Abstract
A method and apparatus for prediction of the turn rate of a deviated well is disclosed. The turn rate is determined by collecting data for interference, bend length, and rate of turn from a variety of drilled wells. Using regression technique, turning rate is then expressed as a linear function of the ratio of interference to bend length.
