SYSTEM AND METHOD FOR DETERMINING BHA POSITION DURING LATERAL DRILLING

摘要

A method for controlling drilling direction of a bore hole assembly (BHA) while laterally drilling through a formation involves accessing, by a surface steerable system, recent TVD corrected logging history data from a bore hole estimator, iteratively determining, by the surface steerable system, a formation bed dip of the formation being laterally drilled through, repeating the steps of accessing the recent TVD corrected logging history data and iteratively determining the formation bed dip of the formation responsive to additional well information, determining, by the surface steerable system, a most probable statistical match of a well bore positions to predicated well bore positions based on the accessed recent TVD corrected logging history data, the determined formation bed dip and the additional well information and providing, by the surface steerable system, geosteering feedback responsive to the determined most probable statistical match.

1. A method for controlling drilling direction of a bore hole assembly (BHA) while laterally drilling through a formation, comprising:
accessing, by a surface steerable system, recent TVD corrected logging history data from a bore hole estimator; iteratively determining, by the surface steerable system, a formation bed dip of the formation being laterally drilled through; repeating the steps of accessing the recent TVD corrected logging history data and iteratively determining the formation bed dip of the formation responsive to additional well information; determining, by the surface steerable system, a most probable statistical match of a well bore positions to predicated well bore positions based on the accessed recent TVD corrected logging history data, the determined formation bed dip and the additional well information; and providing, by the surface steerable system, geosteering feedback responsive to the determined most probable statistical match.
