  • Patent number: 10883340
    Abstract: Methods and systems for controlling the downhole position and velocity of a work string using a downhole position and velocity controller may be configured or otherwise programmed to account for force compensation. For example, the work string may undergo significant length changes like thermal expansion and elongation or contraction due to inertial forces, self-weight, and wellbore pressure. Also, the downhole conditions (e.g., temperature, internal forces, self-weight, and wellbore pressure) can cause the work string to be overloaded and become damaged if fast or sudden manipulations occur. The dynamic model implemented with the downhole position and velocity controller may be configured to account for the downhole forces experienced by the work string due to downhole conditions to provide the position and velocity movements that should occur at the surface to achieve the desired position and velocity movements downhole.

  • Patent number: 10871762
    Abstract: Techniques are described for controlling drilling operations based on real time measurement and analysis of fluid properties in a drilling environment. Sensor data can be collected that provides measurement(s) of fluid properties (for example, density and rheology) of the drilling fluid (in other words, downhole mud) around the drill. The measurements can be provided to a hydraulic model that calculates downhole pressure loss in the annulus. Based on this calculation, a calculation of equivalent circulating density (ECD) can be performed. In some implementations, the calculations are performed in real time with respect to the collection of the sensor data. The real time pressure loss and ECD calculations can be used to control bottom hole circulating pressures. The results of the calculations may be used to automatically control drilling operations.

    Abstract: A boring tool is movable through the ground. A transmitter supported by the boring tool transmits an electromagnetic homing signal. A portable device monitors the electromagnetic homing signal and receives the electromagnetic homing signal in a homing mode for guiding the boring tool to a target position. A processor generates steering commands for guiding the boring tool based on a bore plan in a steering mode such that at least some positional error is introduced without using the electromagnetic homing signal. Switching from the steering mode to the homing mode is based on monitoring of the electromagnetic homing signal as the boring tool approaches the portable device to then guide the boring tool to the target position location in compensation for the positional error. Intermediate target positions are described as well as guiding the boring tool based on the homing signal so long as the portable device receives the signal.

  • Patent number: 10358880
    Abstract: A pipe handling device and method for use with a horizontal directional drilling system. The pipe handling device stores sections of drill pipe in individual columns within a magazine. The magazine is constructed so that it can be mounted to a boring machine in a pin-up or pin-down orientation. A plurality of signal elements are attached to the magazine and each extend at least partially within a footprint of each column. The signal elements may move from a first position, indicating the column is full of pipe sections, to a second position, indicating the column is not full of pipe sections. A proximity sensor assembly detects movement of the individual signal elements and signals a processor accordingly. These signals indicate whether or not a given column is full of pipe sections.

  • Patent number: 10344587
    Abstract: The operational position of a sliding sleeve is detected using an electrode-type logging tool. The logging tool generates a baseline log of the sliding sleeve in a non-actuated position, and a response log of the sliding sleeve in an actuated position. The baseline and response logs are then compared in order to determine the operational position of the sliding sleeve.

  • Patent number: 10278367
    Abstract: An interactive tracking, monitoring, and reporting platform of domesticated animal activity may be provided. The platform may enable the tracking of domesticated animals within an interactive tracking zone. The tracking activity may be controlled by a rule set defined by the owner and enabled by a tracking device embodied as, for example, a collar worn by the animal. Upon the tracking device's proximal location to detection devices within the interactive tracking zone, an action may be triggered. The trigger may cause an action to be taken by, for example, a device located within the interactive tracking zone. The trigger may cause information to be collected on the domesticated animal's activity by the platform. The platform may then provide a report on the domesticated animal's activity to the domesticated animal's owner. The report may be communicated via a mobile phone application and may comprise real-time data collected on the domesticated animal.

  • Patent number: 10202837
    Abstract: Methods, systems, and techniques for performing automated drilling of a wellbore. The wellbore is drilled in response to a first drilling parameter target (such as weight on bit) that includes a first drilling parameter offset modified by a first drilling parameter perturbation signal. A first drilling performance metric (such as rate of penetration) is measured and is indicative of a response of the drilling to the first drilling parameter target. An output of a first objective function is determined using the measured first drilling performance metric. A first correlation between the output of the first objective function and the first drilling parameter perturbation signal, and an integral of the first correlation, are determined. The first drilling parameter target is updated using the integral modified by the first drilling parameter perturbation signal. The wellbore is drilled in response to the updated first drilling parameter target.

    Abstract: A drilling device with improved fuel efficiency, reduced impact on the environment, and the like is provided. Specifically, a drilling device performs unload control of a compressor when an engine starts up, and brings the air pressure in an air tank to a first air pressure. Moreover, the air pressure in the air tank is kept at the first air pressure while the engine is driven and a flushing mechanism is not driven. In addition, unload control of the compressor is performed when the flushing mechanism starts up, and the air pressure in the air tank is increased to a second air pressure that is higher than the first air pressure. For example, the first air pressure and the second air pressure are a low pressure (0.5 MPa) and a high pressure (1.03 MPa), respectively.
