Continuous survey using magnetic sensors

Various implementations directed to a continuous survey using magnetic sensors are provided. In one implementation, a method may include acquiring continuous survey data during an outrun data acquisition using a survey tool disposed within a previously drilled section of a wellbore. The survey tool may have one or more magnetic sensors, and the survey tool may be configured to ascend within the previously drilled section of the wellbore during the outrun data acquisition. The method may further include transmitting the continuous survey data to a computing system, where the computing system may be configured to generate a continuous survey of the previously drilled section of the wellbore based on the continuous survey data.
