摘要： A system and method for detecting screen-out using a fracturing valve for mitigation, wherein the fracture method can comprise fracturing a well using a fracturing valve, while a downhole pressure is less than a predetermined threshold. The method can also comprise actuating by automated process the fracturing valve from a fracturing position to a nonfracturing position upon detecting by a pressure sensor in the wellbore that the downhole pressure has reached said predetermined threshold.

摘要： 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.
摘要翻译：一个无聊的工具可以通过地面移动。由钻孔工具支撑的变送器传送电磁归位信号。便携式设备监视电磁归位信号并且以归位模式接收电磁归位信号，以将钻孔工具引导到目标位置。处理器产生用于在转向模式下基于钻孔平面引导钻孔工具的转向命令，使得在不使用电磁归位信号的情况下引入至少一些位置误差。从转向模式切换到归位模式是基于在镗刀接近便携式装置时监测电磁归位信号，然后将钻孔工具引导到目标位置，以补偿位置误差。描述中间目标位置，并且只要便携式设备接收信号，就基于归位信号来引导钻孔工具。

摘要： A downhole closed loop method for controlling a drilling toolface includes measuring first and second attitudes of the subterranean borehole at corresponding first and second upper and lower survey stations. The first and second attitudes are processed downhole while drilling to compute an angle change of the subterranean borehole between the upper and lower survey stations. The computed angle change is compared with a predetermined threshold. This process may be continuously repeated while the angle change is less than the threshold. The first and second attitudes are further processed downhole to compute a toolface angle when the angle change of the subterranean borehole is greater than or equal to the threshold. The toolface angle may then be further processed to control a direction of drilling of the subterranean borehole.
摘要翻译：用于控制钻井工具面的井下闭环方法包括测量相应的第一和第二上部和下部测量站处的地下钻孔的第一和第二态度。第一和第二态度在钻井时被处理在井下，以计算上下测量站之间的地下钻孔的角度变化。将计算出的角度变化与预定阈值进行比较。当角度变化小于阈值时，该过程可以连续重复。当地下钻孔的角度变化大于或等于阈值时，第一和第二态度进一步在井底处理以计算工具面角度。然后可以进一步处理工具面角度以控制地下钻孔的钻孔方向。

摘要： A self-guided geosteering assembly having an on-board, automated guidance system that incorporates a detailed subsurface earth model and well path to geosteer the assembly along a formation. While advancing along the formation, the guidance system continually monitors data related to formation characteristics and the formation/tool location, compares the data to the earth model and well path, and adjusts the direction of the assembly accordingly. In addition, the data may be utilized to update the earth model in real-time.

摘要： Drilling tools that may detect and dynamically adjust drilling parameters to enhance the drilling performance of a drilling system used to drill a well. The tools may include sensors, such as RPM, axial force for measuring the weight on a drill bit, torque, vibration, and other sensors known in the art. A processor may compare the data measured by the sensors against various drilling models to determine whether a drilling dysfunction is occurring and what remedial actions, if any, ought to be taken. The processor may command various tools within the bottom hole assembly (BHA), including a bypass valve assembly and/or a hydraulic thruster to take actions that may eliminate drilling dysfunctions or improve overall drilling performance.; The processor may communicate with a measurement while drilling (MWD) assembly, which may transmit the data measured by the sensors, the present status of the tools, and any remedial actions taken to the surface.

The method includes using the at least one sensor module to measure a magnetic field and to generate at least one first signal indicative of the measured magnetic field. The method further includes using the at least one sensor module to gyroscopically measure an azimuth, an inclination, or both of the at least one sensor module and to generate at least one second signal indicative of the measured azimuth, inclination, or both. The method further includes using the at least one first signal and the at least one second signal to calculate a distance between the existing first wellbore and the at least one sensor module, a direction between the existing first wellbore and the at least one sensor module, or both a distance and a direction between the existing first wellbore and the at least one sensor module.
