| 20100012232 | PITTING CORROSION RESISTANT NON-MAGNETIC STAINLESS STEEL - Disclosed are corrosion resistant, non-magnetic austenitic stainless steels containing alloying elements molybdenum, nickel, and copper and further containing small quantities of an additional element selected from the group consisting of a rare-earth element, calcium, cobalt, iridium, osmium, rhenium, rhodium, ruthenium, silver, and a combination thereof. | 01-21-2010 |
| 20100025110 | SYSTEM AND METHOD FOR CONTROLLING THE INTEGRITY OF A DRILLING SYSTEM - A system for monitoring and controlling a load on a downhole component of a well drilling system is disclosed. The system includes: a downhole tool disposed in a drillstring and configured to be movable within a borehole, the drillstring configured to allow a drilling fluid to be advanced therethrough and into the borehole; at least one sensor disposed within the downhole tool for in-situ measurement of at least one physicochemical property of an environment surrounding the downhole tool; and a processor configured to monitor the at least one physicochemical property and at least one of i) provide physicochemical property information to a user during a drilling/steering operation, ii) adjust a load on the downhole component based on the environment information and iii) shut down the system in response to a detection of a measured physicochemical property beyond a selected threshold. | 02-04-2010 |
| 20100108393 | DOWNHOLE MUD MOTOR AND METHOD OF IMPROVING DURABILTY THEREOF - Disclosed herein is a downhole mud motor. The mud motor includes, a stator, a rotor in operable communication with the stator, a polymer in operable communication with the stator and the rotor, and a plurality of carbon nanotubes embedded in the polymer. | 05-06-2010 |
| 20110253373 | TRANSPORT AND ANALYSIS DEVICE FOR USE IN A BOREHOLE - A fluid conveyable device having an interior space receives a payload that may be transported along at least a section of a borehole. The device includes a access control member for conveying the payload between the interior and the exterior of the fluid conveyable device. | 10-20-2011 |
| 20110266054 | At-Bit Evaluation of Formation Parameters and Drilling Parameters - An apparatus for forming a wellbore in a formation may include a bit body and a sensor in the bit body. The sensor may include at least one cutting element and may be configured to generate information relating to a parameter of interest when the drill bit engages a wellbore surface. | 11-03-2011 |
| 20110266058 | PDC Sensing Element Fabrication Process and Tool - A Polycrystalline Diamond Compact (PDC) cutter for a rotary drill bit is provided with an integrated sensor and circuitry for making measurements of a property of a fluid in the borehole and/or an operating condition of the drill bit. A method of manufacture of the PDC cutter and the rotary drill bit is discussed. | 11-03-2011 |
| 20120018141 | WELL TOOL HAVING A NANOPARTICLE REINFORCED METALLIC COATING - A well tool is disclosed. The tool includes a first member having a surface that is configured for exposure to a well fluid, the first member comprising a metallic coating disposed on a substrate, the metallic coating having a plurality of dispersed nanoparticles disposed therein and providing the surface. The tool also includes a second member that is disposed in slidable engagement on the surface of the first member. In another exemplary embodiment, a well tool includes a first member having a surface that is configured for exposure to a well fluid, the first member comprising a metallic alloy, the metallic alloy having a plurality of dispersed nanoparticles disposed therein and providing the surface. | 01-26-2012 |
| 20120024632 | DOWNHOLE SEAL AND METHOD OF LUBRICATING A DOWNHOLE TOOL - A downhole seal includes a body configured to dynamically seal to a portion of a downhole tool and a lubricant microencapsulated in a plurality of shells to form a plurality of micro particles dispersed within the body. | 02-02-2012 |
