| 20090012741 | Location Device with a Gravity Measuring Device - A location device has a gravity measurement instrument in communication with a database which has the locations relative to time of an astronomical object. The location device also has a timepiece indicating the time which may be used to determine the location of the astronomical object. | 01-08-2009 |
| 20090065251 | Downhole Jack Assembly Sensor - In one aspect of the invention, a drill string comprises a drill bit with a body intermediate a shank and a working face, and the working face comprises at least one cutting element. A jack assembly is disposed within the drill bit body and comprises a jack element disposed on a distal end of the assembly. The jack element substantially protrudes from the working face and is adapted to move with respect to the bit body. At least one position feedback sensor is disposed proximate the jack assembly and is adapted to detect a position and/or orientation of the jack element. | 03-12-2009 |
| 20090133936 | Lead the Bit Rotary Steerable Tool - In one aspect of the present invention, a drilling assembly comprises a drill bit comprising a bit body intermediate a working face and a shank. An indenting member adapted to guide the drill bit protrudes from the working face. A flexible portion is disposed above the bit body. | 05-28-2009 |
| 20090152011 | Downhole Drive Shaft Connection - In one aspect of the present invention, a section of a drill string has a drill bit with a body intermediate a shank and a working face, the working face having at least one cutting element. A jack element is disposed within the drill bit body and has a distal end substantially protruding from the working face. A drive shaft is in communication with the jack element and a rotary source. The drive shaft has a first portion secured within a bore of a tool string component in the tool string and a second portion secured within a bore of the drill bit. The first and second portions of the drive shaft are connected at a pin and box connection wherein the first and second portions are automatically connected as the tool string component is mechanically coupled to the drill bit. | 06-18-2009 |
| 20100000794 | Lead the Bit Rotary Steerable Tool - In one aspect of the present invention, a drilling assembly comprises a drill bit comprising a bit body intermediate a working face and a shank. An indenting member adapted to guide the drill bit protrudes from the working face. A flexible portion is disposed above the bit body. | 01-07-2010 |
| 20100108385 | Downhole Jack Assembly Sensor - In one aspect of the invention, a drill string comprises a drill bit with a body intermediate a shank and a working face, and the working face comprises at least one cutting element. A jack assembly is disposed within the drill bit body and comprises a jack element disposed on a distal end of the assembly. The jack element substantially protrudes from the working face and is adapted to move with respect to the bit body. At least one position feedback sensor is disposed proximate the jack assembly and is adapted to detect a position and/or orientation of the jack element. | 05-06-2010 |
| 20100236833 | Displaceable Plug in a Tool String Filter - A filter for a drill string comprises a perforated receptacle having an upper end and a lower end. The upper end of the filter comprises a drilling mud intake, and the lower end of the filter comprises an opening. A displaceable plug is seated on the opening at the lower end. | 09-23-2010 |
| 20100299102 | Location Device with a Gravity Measuring Device - A location device has a gravity measurement instrument in communication with a database which has the locations relative to time of an astronomical object. The location device also has a timepiece indicating the time which may be used to determine the location of the astronomical object. | 11-25-2010 |
