| 20100185395 | SELECTING OPTIMAL WELLBORE TRAJECTORY WHILE DRILLING - A method for selecting an optimal trajectory of a wellbore while drilling the wellbore and a computer program having instructions for the same are disclosed. The method and program may include obtaining data, such as real-time date, related to the wellbore and obtaining data related to drilling limitations. The method and program also obtains data related to production considerations or drilling considerations. A target is selected and the optimal trajectory is selected from possible trajectories to the target. Ideally, the optimal trajectory conforms with the drilling limitations and satisfies one or more of the production considerations or drilling considerations. | 07-22-2010 |

| 20100122847 | METHODS FOR VISUALIZING DISTANCES BETWEEN WELLBORE AND FORMATION BOUNDARIES - A method for displaying a formation model while drilling a wellbore in the formation includes operating a well logging instrument at a measurement point in the formation along a wellbore while the wellbore is being drilled. Measurement data regarding the formation are obtained from the well logging instrument. An actual orientation of a geological structure is determined from the measurement data. A trajectory of the wellbore is displayed in three dimensions as it is being drilled through the formation. While drilling the wellbore, the geological structure is displayed along the trajectory of the wellbore according to the determined actual orientation of the geological structure. The actual orientation reflects an azimuth angle of planes corresponding to the geological structure. The trajectory of the wellbore is changed in response to displaying the determined actual orientation of the geological structure relative to the trajectory. | 05-20-2010 |

| 20080236270 | DETERMINING WELLBORE POSITION WITHIN SUBSURFACE EARTH STRUCTURES AND UPDATING MODELS OF SUCH STRUCTURES USING AZIMUTHAL FORMATION MEASUREMENTS - A method for determining structure in the Earth's subsurface includes generating an initial model of the structure. The initial model includes at least one layer boundary. A wellbore is drilled along a selected trajectory through the Earth's subsurface in a volume represented by the initial model. At least one formation parameter is measured azimuthally along the wellbore. A distance is determined from the wellbore at selected positions therealong to the at least one layer boundary using the azimuthal formation parameter measurements. The initial model is adjusted using the determined distances. In one example, the parameter is resistivity. In one example, the parameter is acoustic velocity. | 10-02-2008 |
