Abstract
⺠Various deviation factors and conditions contributed to borepath deviation. ⺠Correction conditions derive from two models on max. deviation and decision point. ⺠Automated correctional algorithm in section determines the direction of jet flow. ⺠Automated hydraulic correctional drill tool performs the borepath correction. ⺠The technology doesn't need traditional drill bit hoisting or signal transmission.
