| 20100307742 | METHOD OF DETERMINING AND UTILIZING HIGH FIDELITY WELLBORE TRAJECTORY - Various methods are disclosed, comprising obtaining a plurality of raw depth measurements for a wellbore; obtaining survey data about a bottom hole assembly; obtaining depth compensation information; calculating a plurality of compensated depth measurements from the raw depth measurements and the depth compensation information and one or more additional corrections for residual pipe compliance, tide, and rig heave; calculating sag angle and correcting the survey data with the sag angle; determining a high fidelity wellbore trajectory from the compensated depth measurements and the survey data; and then employing the high fidelity wellbore trajectory in various drilling, formation evaluation, and production and reservoir analysis applications. Depth compensation information may comprise at least one of weight on bit, a friction factor, temperature profile, borehole profile, drill string mechanical properties, hookload, and drilling fluid property. The surveys may include both static and continuous surveys. | 12-09-2010 |

| 20090105956 | Methodology and Application of Multimodal Decomposition of a Composite Distribution - A method for analyzing formation data includes decomposing the formation data into simple components that can be used to reconstruct the formation data, wherein the decomposing is performed at a first location and includes a process to minimize an overlap between the simple components; and transmitting parameters representing the simple components to a second location for reconstructing the formation data. A system for analyzing formation data that includes a processor and a memory that stores a program having instructions for decomposing the formation data into simple components that can be used to reconstruct the formation data, wherein the decomposing is performed at a first location and includes a process to minimize an overlap between the simple components; and transmitting parameters representing the simple components to a second location for reconstructing the formation data. | 04-23-2009 |
| 20100149918 | METHOD FOR DISPLAYING GEOLOGIC STRESS INFORMATION AND ITS APPLICATION TO GEOLOGIC INTERPRETATION - A method for displaying geologic stress includes determining magnitudes and directions of principal stresses at at least one a selected location. An analog symbol is generated for each magnitude and direction of the principal stresses. The analog symbols include a magnitude descriptor and a direction descriptor. The analog symbols are stored or displayed. | 06-17-2010 |
| 20100161228 | METHOD FOR ESTIMATING FORMATION DIP USING COMBINED MULTIAXIAL INDUCTION AND FORMATION IMAGE MEASUREMENTS - A method for determining dip of rock formations penetrated by a wellbore using multiaxial induction measurements and imaging measurements made from within the wellbore includes estimating dip from the multiaxial induction measurements. Dip is also estimated from the imaging measurements. The dip is determined by combining the induction and imaging measurements. | 06-24-2010 |

| 20090281462 | Device and method for following the movement of a living being - A system including a sensor measuring a position of movement, an artificial controller converting the signals from the sensor into state variables of full movement, correlated with a reference model, by performing continual adjustments for estimating these variables directly drawn from the signals of the sensor by results drawn from the reference model. The control which is then provided for completing the movement has good synchronization with the portion accomplished without assistance from the system. Such a system may find application for reproducing or completing the walking of a person with a disabled leg. | 11-12-2009 |
