Abstract: A method of drilling a well within a target stratum. The method can include drilling based upon a target window created from previously collected and/or extrapolated data. Data is collected while drilling and the target window can be adjusted “on the fly” as well as updating and correcting previously collected data. The method can be repeated to ensure optimal drilling efficiency and minimal down time while drilling.

Abstract: A geo-steering method for drilling a formation penetrated by multiple wells. The method comprises computing a stratigraphic target formation window, computing a target line utilizing an instantaneous formation dip angle correlated to offset well data from an offset well. The method further comprises calculating a target window from actual drilling data overlaying the target window over the stratigraphic target formation window to drill on the target line, identifying target deviation from target line using overlaid windows, generating a target deviation flag when the overlaid results differ above or below the stratigraphic target formation window or user inputted target deviation flag parameters, wherein the target deviation flag stops drilling by the rig. The method performs another actual survey, creating a new window, starting drilling, creating a new target window, overlaying the two windows and monitoring for target deviations, repeating the process until target depth is reached.

Abstract: A downhole adjustable mud motor for boring wellbores, such as a hole in the earth. The downhole adjustable mud motor has a progressive cavity power section with a power cavity end, wherein the progressive cavity power section has a rotor rotatably captured within a stator and a plurality of fluid flow paths between the stator and the rotor for flowing drilling fluid. A power transmission section can be connected to the power cavity end having a central axis and an offset axis. A first adjustable member can be fastened to the stator. A second adjustable member can have a locking member, a bearing assembly connecting to the transmission assembly, and a fastener operatively connected to the bearing assembly. The locking member prevents compression of the second adjustable member inside of the first adjustable member when drilling fluid flows through the downhole adjustable mud motor.
