  • Publication number: 20260086266
    Abstract: A method for surveying a wellbore includes rotating a wellbore surveying tool in a wellbore. The wellbore surveying tool includes a plurality of magnetometers, a plurality of accelerometers, and, optionally, a plurality of temperature sensors. Sensor measurements are made while the survey tool rotates in the wellbore. A failed accelerometer or a failed temperature sensor is automatically detected from the accelerometer measurements or the temperature measurements. Corrected sensor measurements are computed for the failed sensor from selected ones of the magnetometer measurements, the accelerometer measurements, and the temperature measurements and used to further compute at least one of a wellbore inclination or a wellbore azimuth.

  • Publication number: 20250067168
    Abstract: Systems and methods for estimating tool string depth can include a framework that utilizes machine learning to determine depth and depth uncertainties for the tool string. The framework can take as inputs a casing collar locator signal, a depth, a cable speed, and a timestamp. Then a collar detector function, which can be a machine learning model, can detect a collar and output a certainty level associated with the detection. A collar identifier function can combine that certainty level with a prior collar map and other prior parameters to identify a particular collar and that collar's depth. Then a fusion function can output a depth and depth uncertainty for the collar or for the tool string.

  • Patent number: 11149544
    Abstract: A technique facilitates communication in a subsea well application. The technique involves deployment of a blowout preventer subsea control and telemetry system to a subsea location proximate a wellbore. The blowout preventer subsea control and telemetry system is coupled to both a blowout preventer system and a wireless telemetry system. The wireless telemetry system has a plurality of repeaters deployed along the wellbore. The blowout preventer subsea control and telemetry system is used both to collect data from the wireless telemetry system and to control operation of the blowout preventer system. For example, the blowout preventer subsea control and telemetry system may receive control signals from a surface system and also relay data to the surface system through a common communication line.
