Abstract:
Apparatus, systems, and methods for correcting clock drift between multiple data streams detected during oil or gas drilling operations. The method generally includes drilling a well segment using a drilling rig. During the drilling of the well segment, first and second drilling conditions are detected over a time interval using first and second sensors. First and second data streams based on the detected first and second drilling conditions are received at a surface location. It is then determined, based on a relationship between the first and second drilling conditions, whether the first and second data streams are asynchronous with each other and relative to the time interval. If it is determined that the first and second data streams are asynchronous: an extent to which the first and second data streams are asynchronous is determined; and based on said extent, the first and second data streams are synchronized.
