Abstract: A method can include acquiring data associated with a field operation in a geologic environment; processing the data by partitioning operationally and representing symbolically; formulating a symbolic query for an operating procedure specification; performing a search of the symbolically represented data utilizing the symbolic query and a probabilistic chain model; receiving a search result responsive to the search; assessing compliance with the operation procedure specification utilizing the search result; and issuing a control signal to field equipment utilizing the assessment of compliance.

Abstract: Methods, computing systems, and computer-readable media for detecting sensor malfunctioning status. The method includes receiving sensor measurements of a first type from a first type of sensor, deriving a first value for a metric from the sensor measurements of the first type, receiving sensor measurements of a second type from a second type of sensor, wherein the second measurements of the second type include a second value for the metric, comparing the first value to the second value, determining whether the first type of sensor or the second type of sensor is malfunctioning based on the comparing, and storing or outputting information indicating whether first type of sensor and the second type of sensor are malfunctioning.

Abstract: A method for determining stick slip conditions. The method may include disposing an operating apparatus in fluid communication with a pressure wave transmission medium. At least one pressure measurement device may be disposed at least partially within the pressure wave transmission medium and at some distance from the operating apparatus. One or more pressure waves generated by the operating apparatus may be measured within the pressure wave transmission medium with the at least one pressure measurement device and pressure measurement data may be generated therefrom. The pressure measurement data from the at least one pressure measurement device may be transmitted to a data acquisition system. The pressure measurement data may be analyzed to detect one or more stick slip conditions from one or more variations in the pressure measurement data.

Abstract: A method includes receiving time-series data during operation of one or more equipment systems at a rigsite, and automatically segmenting partitions from the time-series data with respect to an individual pipe of a drillstring using separately and symbolically computed inferred equipment states and activity states. The partitions include an in slips partition for a time interval between setting slips and releasing the slips. The method further includes operating a controller to control one or more of the equipment systems based at least in part on one or more operational sequence times of the in slips partition.

Abstract: A method for predicting a telemetry mode of a downhole tool includes receiving a signal from the downhole tool at a computing system at a surface. The method also includes predicting the telemetry mode of the downhole tool based on the signal. The method also includes switching a telemetry mode of the computing system to match the telemetry mode of the downhole tool. The method also includes demodulating the signal using the computing system after the telemetry mode of the computing system has been switched.

Abstract: A well-logging system may include a tool assembly to be positioned within a borehole of a subterranean formation and to store second data including a second time marker related to a first time marker. The well-logging system may include a controller above the subterranean formation. The controller may process first data including the first time marker, recover the second data, and synchronize the second data based upon the second time marker and the first time marker.
