| 20090283276 | OVERRIDING A PRIMARY CONTROL SUBSYSTEM OF A DOWNHOLE TOOL - A system that is usable with a well may include a piston, a primary control subsystem and an override subsystem. The piston actuates the downhole tool, and the primary control subsystem may be connected to at least one hydraulic line in order to move the piston in response to pressure that is communicated to the tool via the hydraulic line(s). The override subsystem may be connected to the hydraulic line(s) to override the primary control subsystem and move the piston in response to pressure communicated to the tool via the hydraulic line(s). | 11-19-2009 |
| 20100089141 | DOWNHOLE ANNULAR MEASUREMENT SYSTEM AND METHOD - A downhole measurement system may comprise an optional fluid inlet section configured to accommodate fluid flow between a well and a zone surrounding the well. The system may further comprise a flow conditioning section configured to receive the fluid from the fluid inlet section. The flow conditioning section may be configured to produce a substantially homogenized fluid flow. In addition, a measuring section may be provided and configured to measure at least a portion of the fluid flow from the flow conditioning section. The measuring section characterizes a parameter of the fluid flow. In other embodiments, there may be a method for characterizing a parameter of a fluid flow comprising the steps of directing the fluid flow to a flow conditioning section. Other steps may be conditioning the fluid flow to a substantially homogeneous state and measuring a parameter for at least a portion of the fluid flow. | 04-15-2010 |
| 20100193200 | DOWNHOLE PRESSURE BARRIER AND METHOD FOR COMMUNICATION LINES - A technique enables sealing of downhole components by providing a downhole pressure barrier for communication lines. The system comprises a communication line cementing sub that may be coupled into a tubing string. The cementing sub comprises a flow passage, a radially protruding region, a first connector, and a second connector. The first connector is generally disposed on a first longitudinal end of the radially protruding region, and the second connector is disposed on a second longitudinal end of the radially protruding region. Additionally, a passageway extends through the radially protruding region from the first connector to the second connector. The first and second connectors enable routing of a communication line through the radially protruding region. | 08-05-2010 |
| 20100319931 | SYSTEM AND METHOD FOR CONNECTING COMMUNICATION LINES IN A WELL ENVIRONMENT - A technique enables the efficient connection of communication lines in a well application by substantially reducing online rig assembly time. The technique reduces online time of the rig by sealably fastening a first connector of a downhole connection assembly to a segment of a communication line during offline assembly time to substantially reduce the online time requirements. The first connector is later connected to a corresponding second connector while the rig is online to complete the downhole connection assembly that joins communication line segments. | 12-23-2010 |
| 20100319936 | METHOD FOR EFFICIENT DEPLOYMENT OF INTELLIGENT COMPLETIONS - A technique enables efficient deployment of instrumentation gauges in a wellbore. The technique comprises preparing offline a plurality of assemblies having a combined packer and gauge mandrel with an associated gauge. Each assembly is combined with a segment or length of instrumentation cable that is fully spliced with the gauge during offline assembly time. Various splice halves also can be assembled during offline assembly time. | 12-23-2010 |
| 20110011580 | WIRELESS TRANSFER OF POWER AND DATA BETWEEN A MOTHER WELLBORE AND A LATERAL WELLBORE - A technique enables wireless communication of signals in a well. The technique is employed for communication of power signals and/or data signals between a mother wellbore and at least one lateral wellbore. A first wireless device is positioned in a mother wellbore proximate a lateral wellbore, and a second wireless device is positioned in the lateral wellbore. The power and/or data signal is transferred wirelessly between the first and second wireless devices via magnetic fields. A plurality of the first and second wireless devices may be employed in cooperating pairs to enable communication between the mother wellbore and a plurality of lateral wellbores. | 01-20-2011 |
