  • Patent number: 11555352
    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: 11199061
    Abstract: For a wellbore drilled in a low or subnormal pressure reservoirs, a static loss rate of drilling fluid is monitored within a limit of a drilling rate. In reaching the limit, the annulus is closed off to returns using a rotating control device, or the annulus may remain open to the atmosphere at surface. Operations may not be able to keep the annulus filled with a mud cap so pressurized mud cap drilling cannot be sustained. Instead, an initial fluid level of the mud cap is defined in the annulus. Drilling the wellbore with the mud cap then involves: pumping a sacrificial fluid through the drillstring without returns to surface through the annulus, and monitoring the initial fluid level in the annulus to detect a change. Monitoring uses downhole instrumentation to measure pressure, temperature, and gas level of the mud cap. In response to the detected change, the drilling can be further controlled, including stopping the drilling, turning off pumps, and possibly bullheading the well.

  • Patent number: 11002093
    Abstract: A semi-autonomous downhole taxi with fiber optic communication is described. The taxi includes a housing configured to travel within a horizontal section of a wellbore. A docking station is detachably attached to the housing. The docking station is configured to couple to a wireline to pass the taxi through a vertical section of the wellbore. The docking station is configured to be detached from and re-attached to the housing. A fiber optic cable spool is attached to and carried by the housing. A fiber optic cable is wound on the fiber optic cable spool. The fiber optic cable mechanically connects the docking station and the housing. The fiber optic cable is configured to unspool from the fiber optic cable spool as the housing, detached from the docking station, travels through the horizontal section of the wellbore. The fiber optic cable is configured to pass data between the docking station and the housing.

  • Patent number: 10954719
    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: 10920576
    Abstract: A method for controlling drilling direction of a bore hole assembly (BHA) while laterally drilling through a formation involves accessing, by a surface steerable system, recent TVD corrected logging history data from a bore hole estimator, iteratively determining, by the surface steerable system, a formation bed dip of the formation being laterally drilled through, repeating the steps of accessing the recent TVD corrected logging history data and iteratively determining the formation bed dip of the formation responsive to additional well information, determining, by the surface steerable system, a most probable statistical match of a well bore positions to predicated well bore positions based on the accessed recent TVD corrected logging history data, the determined formation bed dip and the additional well information and providing, by the surface steerable system, geosteering feedback responsive to the determined most probable statistical match.

  • Patent number: 10914120
    Abstract: A Rotary Steerable System (RSS) includes a flexible collar coupled therein that reduces the stiffness of the RSS and permits a tighter turning radius to be achieved. The positioning of the flexible collar between the steering section and the controller of the RSS further improves the turning radius, and may permit a push-the-bit system to operate similar to a point-the bit system. The flexible collar permits communication therethrough between controller and the steering sections of the RSS. The RSS may be arranged as a modular system to receive various configurations of a flexible collar and may operate with no flexible collar installed. The modularity enables tuning of the stiffness of an RSS to achieve different steering objectives.

  • 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.
