Abstract: A method and system for using GPS signals and a magnetic field to track an underground magnetic field source. A tracker having an antenna for detecting the magnetic field and a GPS receiver is coupled to a processor. The magnetic field is used by the antenna to direct the tracker to a field null point. Once multiple measurements of the field are taken, the changes in signal strength as the absolute position of the tracker is changed, are used to determine whether the closest field null point is in front of or behind the underground beacon. The position and depth of the beacon can then be estimated.

Abstract: A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.

Abstract: An optimizable beacon and method of using the same. The beacon has an onboard power source with a finite capacity. The system uses a capacitor bank to adjust the capacitance of the beacon, thereby maximizing the signal provided considering conditions, rather than simply using a theoretical value. With the specified capacitance being used, the beacon may be optimized in both a high and low power mode by driving the current to ensure the measured power is greater than or equal to a target. The system may also have a motion sensor to toggle the power off, or to a low-power mode, when the beacon is moving, and location measurements are not taking place. The optimization process may also consider the chemistry of the battery being utilized.

Abstract: An antenna arrangement. The arrangement uses four conductive loops, each within a distinct plane from the other conductive loops. The four conductive loops have a common center point. Each loop is within a dipole magnetic field, and detects a component thereof. By balancing the signals received between matched pairs of the conductive loops, the difference between the signals can be used to guide the antenna arrangement to a null point—that is—a point in the magnetic field where each pair of conductive loops is balanced. The antenna arrangement can further be used to determine the depth of the dipole field source using the magnitude of the field.

Abstract: A method and apparatus for installing a monitoring cable or other utility near an existing pipeline. An electromagnetic signal may be induced on the pipeline, either directly, or by transmitting a signal from a vehicle carrying a sensor array. The sensors disposed on the vehicle communicate with a processor to determine a distance and orientation of the vehicle relative to the pipeline. The signal may be electromagnetic, acoustic, capacitive, or the like. A plow or other digging tool may be on the vehicle or a secondary vehicle. Such a digging tool opens a trench and installs the cable along a path disposed next to the pipeline within an acceptable distance range from the pipeline. The vehicle may be remotely or automatically operated.

Abstract: A method for detecting a beacon signal using an above-ground tracker. The tracker comprises an antenna assembly comprising a plurality of antennas. Each antenna is oriented in a different direction. During operation, if the beacon signal is interrupted due to a local noise source, transmission of the beacon signal is stopped. The tracker then detects radiation from the local noise source and the processor determines a direction from which peak ambient noise arrives at the tracker. The beacon signal is then resumed. A processor included in the tracker excludes any signals generated by the antenna assembly that are representative of radiation that arrived at the tracker from the same direction the peak ambient noise arrived at the tracker. The tracker then detects the beacon signal using the non-excluded signals.

Abstract: A system for locating an underground utility line using a beacon positioned within a downhole tool. The beacon comprises a magnetic sensor formed from one or more ferrite rods. The rods are arranged such that no rod is orthogonal to the longitudinal axis of the beacon housing. The magnetic sensor detects the presence of an underground utility line and sends a signal to an above-ground tracker indicating that a line has been detected. An above-ground locator may be used to determine the position of the line relative the beacon, so that the downhole tool may be steered away from the line.

Abstract: A locating and marking device. The device has one or more antennas capable of detecting a signal emanating from an underground line. A marking device, such as a paint canister, is located on the frame of the device. This marking device leaves a physical or virtual mark at an above-ground path overlying the underground line. A processor receives signals from the antennas and directs the device to place the marking device above the above-ground path. The marking device may move back and forth on a frame of the device, or the device may steer to maintain the marking device in the proper position.
