  • Patent number: 9995840
    Abstract: A drilling rig apparatus is disclosed for improving geosteering control by reducing the amount of bandwidth necessary to convey log data to the surface in real time. A bottom hole assembly receives measurement data from azimuthal measurement sensors. The BHA sorts the measurement data into appropriate bins in a radial plot. The BHA selects a hemisphere for transmission of the measurement data in those bins for the selected hemisphere, instead of transmitting the data for all bins in the plot. The BHA may average the data in the bins for the selected hemisphere with the data of the mirroring bins in the non-selected hemisphere. The BHA transmits the measurement data to a surface controller, which mirrors the data transmitted to the corresponding bins in the non-selected hemisphere to reconstitute the full set of data for the radial plot, which is used for image log generation, geosteering and other control functions.

  • Patent number: 8893808
    Abstract: A self-centering tool for use in a wellbore includes a centering mechanism, a biasing mechanism, and a release mechanism. The centering mechanism includes at least one arm that is configured to move from a first position to a second position. The arm urges a centerline of the tool towards a centerline of the wellbore when in its second position. A biasing mechanism is coupled to the centering mechanism and urges the arm from its first position to its second position. The release mechanism is electro-mechanically actuated. In its locked position, the release mechanism prevents the arm from moving towards its second position, while in its released position the arm is able to move towards its second position. The release mechanism is a split-spool type mechanism. A control system that includes one or more sensors controls the operation of the release mechanism.

  • Patent number: 8875808
    Abstract: A method for conveying logging tools (LT) and obtaining well log data from a wellbore is disclosed. The method includes running a drill string (DS) including a landing sub (LS) disposed near the lower end into a wellbore. A logging tool string (LTS) is inserted into the upper end of the DS bore. A fluid is pumped into the upper end of the DS bore to assist movement of the LTS. As the fluid is pumped behind the LTS, the cable at the surface is spooled out and the fluid pressure is monitored. The landing assembly of the LTS is landed in the LS. A diagnostic test is activated and run to determine proper functioning of the LT. A release mechanism releases the running tool portion of the LTS. The cable is spooled in. The drill pipe string is pulled upward in the wellbore as the LT are recording data.

  • Patent number: 8863836
    Abstract: The present invention is directed to methods and systems for obtaining log data on a cased wellbore concurrently with wellbore cleanout operations. In some such embodiments, a combination of at least one cleaning means and at least one logging tool are integrated or otherwise affixed to a common workstring, such that both wellbore cleanout and logging operations can be accomplished without having to remove the workstring from the well between such operations. In some such embodiments, the one or more logging tool(s) transmit information about the cased wellbore to the surface wirelessly. In some or other such embodiments, such information is transmitted via cable, in real-time or in batch mode. In some or still other such embodiments, such information is stored in memory and accessed subsequent to the workstring being extracted from the wellbore.

  • Publication number: 20140262250
    Abstract: The present disclosure provides a system and method for inferring one or more physical property parameters of a sub-surface media by inverting converted wave data acquired during a seismic survey. Composite seismic traces are generated at a plurality of survey azimuths (step 609). These composite traces are composed such that their amplitudes are free of effects of subsurface anisotropy. At least one of the generated composite seismic traces is then inverted by isotropic inversion to determine a property parameter of the subsurface media (step 623).

  • Patent number: 8813869
    Abstract: Methods and related systems are described for measuring and analyzing refracted acoustic energy. A plurality of receivers mounted are on a downhole tool, and are arranged and adapted to receive refracted acoustic energy from a downhole formation. Measurements of refracted acoustic energy is analyzed such that information relating to an azimuthal direction relative to the downhole tool of an interface within the downhole formation can be estimated. The receivers can be mounted on a drill collar as part of a LWD tool and steering of the drilling trajectory can be based in part on the estimated formation information.

  • Patent number: 8800654
    Abstract: A wellbore machining device is proposed for machining a tubular component of a wellbore. The device includes a control unit at the surface level of the wellbore and a down-hole tool unit connected to the control unit through a wire line. The tool unit includes an elongated guide member, a tool member movably supported on the guide member with respect to at least three axes of motion and a plurality of actuators controlled by the control unit and adapted to move the tool member with respect to the axes of motion. The tool unit further includes two anchor members each mounted to an axial end of the guide member and adapted to releasably clamp the tool unit to the tubular component. The control unit and the tool unit form a computer numerical control device (CNC device) wherein the actuators are electric servo motors controlling an actual position of the tool member with respect to a path and/or a sequence of desired position defined by the control unit.
