Abstract: A device for centering a sensor assembly in a bore comprises a plurality of arm assemblies connected first and second support members. Each arm assembly comprises a first arm pivotally connected to the first support member, a second arm pivotally connected to the second support member, and a third arm pivotally connected between the first and second arms. The third arm is pivotally connected to a third support member positioned axially between the first and second support members. The third arm extends across the longitudinal axis of the device so that in use each arm assembly contacts opposite sides of the bore to centralise the sensor assembly in the bore.

Abstract: A downhole tool and method of utilizing the downhole tool to make measurements in a wellbore formed in a formation and having different wellbore diameters. The downhole tool generally includes a tool body defined along a longitudinal central axis and having an internal passage extending longitudinally therethrough and an external pocket extending therealong; a sensor module having a sensor and being deployed within the external pocket; a spacer deployed in the external pocket, the spacer positioned between the sensor module and the tool body; and a clamp attached to the tool body, the clamp overlaying both the sensor module and the spacer to confine the sensor module within the external pocket. The spacer may have an inner concave surface engaging the sensor module and an outer convex surface seating in the external pocket.

Abstract: A method for configuring a logging module for logging sensors deployment based on a sensing data acquisition objective includes selecting a tool body, selecting at least one type of sensor, and selecting at least one type of roller. The method also includes incorporating the at least one selected type of sensor onto the at least one selected type of roller to provide at least one sensor roller, and mounting the at least one sensor roller into a compressible mounting assembly provided in the tool body to provide the logging module.

Abstract: A system for drilling a well may be adapted to process signals received from a fiber optic cable located in the casing of a previously drilled well or wells. The fiber optic cable may act as a distributed sensor receiving acoustic signals generated during the drilling of the well, and the system may be programmed to process the signals from the fiber optic cable to locate the borehole of the well being drilled, including its location relative to the previously drilled well or well. The system may be used to automatically update a well plan for the well being drilled responsive to information about the location of the borehole and also may be used to automatically adjust one or more drilling parameters or drilling operations responsive to the location of the second well borehole.

Abstract: A geological projection system may receive seismic survey data, the seismic survey data including a seismic surface of a geological feature. A geological projection system may receive resistivity sensor data from a downhole resistivity sensor, the resistivity sensor data being for a reference length uphole of a reference depth. A geological projection system may generate a sensed surface over the reference length using the resistivity sensor data. A geological projection system may generate a displacement field of a difference between the sensed surface and the seismic surface for the reference length. A geological projection system may apply an uncertainty model to at least one of the resistivity sensor data, the seismic survey data, or the displacement field, the uncertainty model generating an output including an uncertainty distribution of a projected surface of the geological feature downhole of the reference depth.

Abstract: The present invention relates to a ground subsidence detection apparatus, which is capable of continuous detection of ground subsidence, predicts the occurrence of sinkholes and thus can preemptively prevent a sinkhole from forming, and due to having a simple structure, can increase durability and reduce cost. Provided is a ground subsidence detection apparatus exhibiting an alarm color using reflection of a light source and a detection weight, which, without using a separate power source, falls due to gravity in the event of cavity formation in the ground, or falls due to ground movement when ground movement occurs.

Abstract: Systems and methods for directional drilling are described. The system includes one or more controllers and is configured to receive data from a plurality of downhole sensors, provide operational control signals, determine a relationship between different parameters, receive current data including at least one of current differential pressure (DP), weight-on-bit (WOB), or rotations per minute (RPM) of a drill bit, and estimate at least one of current toolface orientation or current shock and vibration of the drill bit using the current data and the determined relationship. The system is further configured to provide operational control signals that may adjust the current toolface orientation to a desired toolface orientation. Current WOB and/or current RPM are adjusted to minimize current shock and vibration of a portion of a bottom hole assembly (BHA).

Abstract: A remotely actuated clamping device for a borehole seismic sensing system. The remotely actuated clamping device includes a clamping mechanism configured to engage a surface of a borehole by actuation of the clamping mechanism. The remotely actuated clamping device also includes a fluid based actuator configured to actuate the clamping mechanism. The fluid based actuator includes a chamber configured to be kept at a pressure that is isolated from an ambient pressure of the borehole. The fluid based actuator also includes a piston within the chamber. The chamber receives a pressurized fluid to move the piston within the chamber to actuate the clamping mechanism. The pressure used to actuate the clamping mechanism is independent of the ambient pressure of the borehole. Also disclosed are methods of operating the device.
