COMMON PROBLEMS
COMMON DRAWBACKS

• - Poorly formatted data files
• - Requires manual file generation by service
  company
• - Requires manual loading by the geologist

Manual input of lithology data into office
databases - Manual entry of formation top picks
into office databases - Restricted sharing of
geological information -

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
