20090166035 | Borehole Imaging and Orientation of Downhole Tools - Methods of generating radial survey images of a borehole and methods of orienting downhole operational tools are disclosed. The disclosed techniques are used to generate a radial survey of the borehole in the form of one or more rose-plots and/or a radial image of the borehole and surrounding area that can be used to properly orient downhole operational tools in the desired direction. The tool string includes, from the top to bottom, a telemetry module, a non-rotating centralizer, a motor module, an imaging sonde used to survey the borehole, a rotating centralizer and a downhole operational tool. The motor module can be used to rotate the imaging sonde to generate the radial survey and then rotate the downhole operational tool to the desired direction based upon a review of the radial survey. | 07-02-2009 |
20120180562 | LOGGING TOOL SONDE SLEEVE - A logging tool for use in a wellbore having a sensor portion for making measurements. The tool has a sleeve enclosing the sensor portion and made of a material that is transparent to the measurements being made. One or more structural elements having physical characteristics different from the material comprising the sleeve are carried on the sleeve to enhance the mechanical properties of the sleeve. | 07-19-2012 |

20140338888 | System and Method for Enhancing Hydraulic Fluids for Down Hole Use - An enhanced hydraulic fluid comprises a conventional hydraulic fluid in combination with a predetermined amount of benzene by volume relative to the conventional hydraulic fluid. The predetermined amount of benzene preferably comprises between about 1.0% to about 20.0% benzene by volume, more preferably between about 1.5% to about 10.0% benzene by volume, and most preferably between about 2.0% to about 5.0% benzene by volume. The conventional hydraulic fluid may comprise electronics coolant liquids and oils. Conventional hydraulic fluids that may be mixed with benzene in the volumes described above include, but are not limited to, FLUORINERTS™ that include FC-43 and FC-70, including any perfluorinated, partially fluorinated, or partially chlorinated alkane with between about 3 to about 18 carbon atoms; mineral oils that include CAPELLA™ brand mineral oil; esther oils (synthetic or natural) that include formidals, and MIDEL™ brand esther oils. | 11-20-2014 |
