Abstract: A visualization system for providing a preview of data obtained in a borehole and available for selection and a helmet for visualization and monitoring are described. The visualization system includes a processor configured to process the data based on user input and instructions and provide output for display on a display device; a computer-readable medium configured to store the instructions, the instructions including commands to output values of two or more types of parameters at two or more depth values for display; and a helmet including a visor configured to display the values of the two or more types of parameters at the two or more depth values.

Abstract: A visualization system for visualizing data obtained in a borehole includes a processor configured to process the data based on user input and instructions and provide output for display on a display device. The system may also include a computer-readable medium configured to store the instructions, the instructions including commands to output values of two or more types of parameters at two or more depth values. The instructions may include commands to provide a perspective top-down or bottom-up fly-through display of the borehole including a zoomed-in image of values closest to a user. The processor may also output a display of a photographic image at each of the two or more depth values based on a correspondence between the values of the two or more types of parameters and the plurality of parameters associated with the photographic image.

Abstract: An apparatus for evaluating an earth formation intersected by a wellbore may include a logging tool conveyed into the wellbore through a drilling tubular, a speed control device associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the speed control device varies an annular flow space between the speed control device and a surface adjacent to control speed. The flow space may be varied using a annular member that flexes between a nominal diameter and a second larger diameter.

Abstract: A method for presenting measurements of properties of a subsurface material to a user includes: conveying a carrier through a borehole penetrating the subsurface material; performing a plurality of measurements of multiple properties of the subsurface material at multiple depths in the borehole using a plurality of downhole tools disposed at the carrier; constructing, with a processor, a three-dimensional mathematical model of the subsurface material using the plurality of measurements, the model having data from the plurality of measurements of the multiple properties; receiving, with the processor, an input from a user directing the processor to generate a three-dimensional image of the subsurface material as seen from a virtual viewer-window viewing the model, the input having a three-dimensional position and three-dimensional viewing direction of the virtual-viewer window within the model; generating the three-dimensional image with the processor; and displaying the generated three-dimensional image on a

Abstract: In one aspect, an apparatus for conveying a tool while drilling a wellbore is provided. The apparatus includes a line coupled to the tool, a conveying assembly coupled to the line, the conveying assembly located at a surface and configured to release the line to convey the tool into the drill string and a sub including a passage for the line to pass therethrough. The apparatus also includes a measuring device configured to determine a position of the tool within the drill string by determining a length of the line that is conveyed along with the tool into the drill string.
