Apparatus, System and Methods for Alerting of Abnormal Drilling Conditions

摘要

A method of monitoring drilling conditions includes acquiring raw data from drilling equipment and conditioning the raw data to generate conditioned data. Conditioning the raw data includes removing outlier data values and/or filtering out noise. The method further includes processing the conditioned data to generate output values. Processing the conditioned data includes determining a slope of a first set of data values of the conditioned data. The first set of data values correspond to a regression length of time. Processing the conditioned data further includes determining whether a difference between the slope of the first set of data values and a median slope determined over a median window of time exceeds a threshold. The method also includes generating an alarm based on the output values to indicate an abnormal drilling condition.

1. A method of monitoring drilling conditions, the method comprising:
acquiring raw data from drilling equipment; conditioning, by a data conditioning module, the raw data to generate conditioned data, wherein conditioning the raw data comprises removing outlier data values and/or filtering out noise; processing, by a data processor, the conditioned data to generate output values for use in alarm generation, wherein processing the conditioned data comprises:
determining a slope of a first set of data values of the conditioned data, the first set of data values corresponding to a regression length of time; anddetermining whether a difference between the slope of the first set of data values and a median slope determined over a median window of time exceeds a threshold; and generating, by an alarm generator, an alarm based on the output values to indicate an abnormal drilling condition.
