20120061559 | DOWNHOLE SENSOR TOOL FOR NUCLEAR MEASUREMENTS - A downhole measurement apparatus includes a tool body supporting a logging tool. The logging tool includes a detector outsert coupled into and exposed through an exterior pocket of the tool body to position the outer surface of the outsert adjacent or in close proximity to the outer diameter of the tool body. A stabilizer or off-center stabilizer may be provided to further deflect the outsert portion of the logging tool toward an earth formation to increase detector proximity to the formation. The axial distance between the detector and a nuclear source can be calibrated using configurations of the nuclear source holder and the outsert. Retention mechanisms for the source holder and the outsert further enhance proximity and calibration. | 03-15-2012 |
20120096935 | DOWNHOLE SENSOR TOOL WITH A SEALED SENSOR OUTSERT - A downhole sensor tool includes a sensor outsert coupled into an exterior pocket of the tool body. The sensor outsert is a pressure vessel with an exterior electrical connector coupled to the interior sensor. The sensor outsert contains a sensor, and is pressure-sealed about the sensor. The outsert includes an electrical connector coupled to the sensor. The electrical connector maintains the pressure seal of the outsert. The electrical connector may be a hermetic connector. The electrical connector can be coupled to an electrical connector or a hermetic connector of the tool body while maintaining the sealing of the pressure vessel. | 04-26-2012 |
20120111632 | FORMATION TESTER PAD - A formation tester seal pad includes a support member and a deformable seal pad element including an outer sealing surface having a plurality of raised portions and adjacent spaces. In some embodiments, the raised portions are deformable into the adjacent spaces in response to a compressive load on the outer sealing surface. In some embodiments, the support member includes an inner raised edge and an outer raised edge to capture the deformable seal pad element. In some embodiments, a deformable seal pad element includes a volume of seal pad material above a support member outer profile and a volume of space below the outer profile. In some embodiments, the space volume receives a portion of the seal pad volume in response to a compressive load. | 05-10-2012 |
20120182831 | ACOUSTIC VELOCITY MEASUREMENTS USING TILTED TRANSDUCERS - Apparatus, systems, and methods may operate to emit acoustic pulses into a drilling fluid in a well bore, using a first acoustic transducer in a downhole tool, and detecting the acoustic pulses after reflection from the wall of the well bore, using a second acoustic transducer in the downhole tool. The faces of the first and second acoustic transducers are non-parallel. Further activities include emitting additional acoustic pulses into the drilling fluid using the second acoustic transducer, and detecting them using the second acoustic transducer. The acoustic velocity of the drilling fluid can be determined based on respective travel times. Additional apparatus, systems, and methods are described. | 07-19-2012 |
