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.

An apparatus associated with a drilling rig includes a surface steerable system for controlling drilling direction of a bottom hole assembly (BHA). The surface steerable system is configured to receive drilling rig parameters from the BHA. A database stores historical data related to the drilling rig. The historical data relates to previously tracked operations of the drilling rig. The surface steerable system is further configured to perform a plurality of tracking functions with respect to the drilling rig parameters. The plurality of tracking functions cause the surface steerable system to track drilling rig parameters from sensors associated with the drilling rig, access the database of the historical data relating to previously tracked operations of the drilling rig and control operating functions of the drilling rig responsive to at least one of the drilling rig parameters from the sensors associated with the drilling rig and the historical data from the database.

A method for determining a total vertical depth (TVD) for a well plan involves measuring differences between a projected BHA position at a depth of a survey station and a calculated BHA position based upon a minimum curvature method at the depth of the survey station. The differences are accumulated at each survey station with respect to the BHA position. Real time TVD corrected gamma logs are generated responsive to the accumulated differences of the BHA position.

A surface steerable system coupled to a drilling rig receives BHA information from a bottom hole assembly (BHA) located in a borehole. The BHA information corresponds to a first location of the BHA with respect to a target drilling path and geological formation drift information. The surface steerable system calculates a toolface vector to create a convergence path from the first location of the BHA to the target drilling path that accounts for geological formation drift defined by the geological formation drift information such that the BHA will converge with the target drilling path by drilling in accordance with the toolface vector. The surface steerable system causes at least one control parameter to be modified in order to alter a drilling direction of the BHA based on the calculated toolface vector and transmits the at least one control parameter to the drilling rig to target the BHA in accordance with the calculated toolface vector.
