Apparatus and method for monitoring well logging information

摘要

A method and apparatus monitors well logging information obtained from a logging apparatus moveable in an earth borehole. In a disclosed embodiment, observers are established for determining the presence of specified characteristics of the logging information and generating observation-representative signals in response thereto. A knowledge base is provided, and contains a number of stored observations and stored situations which are linked by specified relationships, for responding to the observation-representative signals by computing and outputting an inference of a stored situation which is inferred from a stored observation corresponding to the observation-representative signals. In a disclosed embodiment, the knowledge base is responsive to observation-representative signals for establishing at least one confirming observer. The confirming observer is operative to determine the presence of further specified attributes of the logging information and to generate confirming observation-representative signals in response thereto. The knowledge base is also responsive to the confirming signals in its computation of the inference.
