20120139748 | Borehole Array for Ranging and Crosswell Telemetry - A borehole array for ranging and crosswell telemetry is disclosed along with certain methods for employing such a borehole array. Some embodiments of the borehole array include electrically coupled reference nodes distributed along the length of a reference well. Each reference node includes a solenoid operated by a control unit. The control unit employs the solenoid to generate a magnetic field for guiding a bottomhole assembly in a nearby well. The control unit further serves as a communications intermediary between the bottomhole assembly and a surface facility. The bottomhole assembly can be guided in turn by subsequent reference nodes of the array and employ the closest reference node as a communications link to the surface. Moreover, the use of multiple reference nodes offers greater precision in determining the bottomhole assembly's position relative to the reference well. The borehole array can be used to guide multiple drilling operations concurrently. | 06-07-2012 |
20120188091 | METHOD AND APPARATUS FOR DETERMINING AND DISPLAYING GEOSTEERING INFORMATION - A method and system to render a graphic display that includes a color-coded risk indicator to facilitate the steering of a drill string during subterranean drilling. The system comprises a receiver to receive measurement data from downhole instrumentation forming part of the drill string during the drilling of a well bore in a geological formation, and an exit risk determining module to determine an exit risk value based at least in part on the measurement data. The exit risk value is indicative of a risk of exiting of the formation by the drill string. A display module is provided to render the graphic display of decision information, to assist steering of the drill string. The color-coded exit risk indicator comprises a colored area having a color indicative of the exit risk value, the color of the colored area being changeable in response to changes in the exit risk value. The graphic display may show a wellbore trajectory in relation to a formation boundary, with the color-coded risk indicator comprising an area extending between the wellbore trajectory and the formation boundary. | 07-26-2012 |
20140022088 | ADVANCED INGROUND OPERATIONS, SYSTEM, COMMUNICATIONS AND ASSOCIATED APPARATUS - Systems, apparatus and methods are described for purposes of initiating a response to detection of an adverse operational condition involving a system including a drill rig and an inground tool. The response can be based on an uphole sensed parameter in combination with a downhole sensed parameter. The adverse operational condition can involve cross-bore detection, frac-out detection, excessive downhole pressure, a plugged jet indication and drill string key-holing detection. A communication system includes an inground communication link that allows bidirectional communication between a walkover detector and the drill rig via the inground tool. Monitoring of inground tool depth and/or lateral movement can be performed using techniques that approach integrated values. Bit force based auto-carving is described in the context of an automated procedure. Loss of locator to drill rig telemetry can trigger an automated switch to a different communication path within the system. | 01-23-2014 |
20140191879 | CASING DETECTION TOOLS AND METHODS - Methods and tools for detecting casing position downhole is presented. The method utilizes electromagnetic. (EM) tools with tilted antenna systems to detect casing position. Sometimes titled antenna designs also increase EM tools' sensitivity to formation parameters, which can lead to false signals for casing detection. In addition, it is very difficult to distinguish measured signals between a casing source and a formation source. The methods presented help to distinguish between the two sources more clearly. The methods and tools presented also help to minimize those environmental effects, as well as enhance the signals from a surrounding conductive casing. The methods herein provide ideas of EM tool's design to precisely determine casing position within a certain distance to casing position. | 07-10-2014 |
20140327551 | OIL PORT POSITION SENSING DEVICE - A portable apparatus for sensing position of an oil port on a rotating element (e.g. the wheel or track of a heavy vehicle) has a position sensor in electrical communication with a wireless transmitter. The wireless transmitter is configured to receive signals from the position sensor and to send signals to a wireless receiver. The apparatus further has a mounting structure (e.g. a magnet) for temporarily mounting the apparatus on the rotating element. An indicium on the apparatus associated with a desired service action to be performed on the rotating element correlates an angular position of the oil port to a pre-determined reference position of the position sensor, the angular position of the oil port being a correct position for performing the desired service action. In use, the apparatus is mounted on the rotating element so that the indicium points at the oil port and then the rotating element is rotated until the receiver indicates that the oil port is in the correct position. | 11-06-2014 |
