Abstract:
1. A method of drilling a well with a bit within a target subterranean reservoir comprising the steps of: a) calculating an estimated formation dip angle; b) drilling the well with a logging while drilling measurement tool (LWD tool) and obtaining real time data representative of the characteristics of the reservoir; c) collecting information from the LWD tool at the well surface location; d) transmitting information to a remote control unit; e) calculating a target line that creates a top and bottom of the formation utilizing an instantaneous formation dip angle (ifdip), and wherein the ifdip is calculated based on the real time representative data correlated to an offset well data generated from an offset well; f) projecting a target window for drilling the well; g) projecting a target window deviation; h) generating a target window deviation flag; i) transmitting the target window deviation flag to the well surface location; and j) ceasing the drilling of the well to perform a well survey.
