Abstract
A system and method of directionally steering a bottom hole assembly (“BHA”) by receiving data indicative of a directional trend of the BHA and a projection to bit depth; determining a location of the BHA based on the received data; comparing the location of the BHA to a planned drilling path to identify an amount of deviation; automatically creating a modified drilling path based on the amount of deviation and a predicted trend of a downhole parameter; detecting a trend of the downhole parameter while drilling along the modified drilling path; and automatically creating a further modified drilling path when the trend of the downhole parameter is a reversal of the predicted trend of the downhole parameter. The predicted trend of the downhole parameter is an increase of a d-exponent factor or a d-exponent-corrected factor with an increase in depth.
