6. Summarized Benefits of mudLog Object Usage Mudlog object usage accelerates the delivery of geological data to decision making applications Automate or semi-automate the update of geological models and prognosed formation tops Feed petrophysics tools and workflows as soon as geological information is available Report on operational data over a geological interval to determine formation characteristics Deliver important operational comments and parameters Sharing and integration of geological prognosis, wellsite interpretations and cuttings lithology Standardized sharing of geological data eliminates inaccuracy
