Log Interpretation

Who Should attend:

The course has been designed to enable the explorationist\development and production geologist to evaluate and integrate wireline log data. The increasingly precise control required by geoscientists in basin/field/well studies can only be achieved through the application of detailed log interpretation.

Overview:

The course programme includes exercises to provide participants with hands-on experience and confidence in handling log and petrophysical data and interpretation. The extensive practical element emphasises how to apply wireline log data in order to enhance well/field correlations, sequence recognition, lithology and reservoir characteristics.

Content:

This short course will provide a basic understanding in the following elements:

• The logging environment, introduction to the borehole.
• Conventional wireline logs (how and what they measure and how to spot problems)
  1. Caliper
  2. Tension
  3. Gamma ray
  4. Spectral gamma ray
  5. Spontaneous potential
  6. Resistivity
  7. Density
  8. Neutron porosity
  9. PEF
  10. Sonic
• Data QA and depth matching (log to log and core to log)
• Interpretation of lithologies from conventional logs
• Quick look interpretation of porosity and hydrocarbons
• Some sedimentological indications from wireline log patterns
• Zoning a section for reservoir engineering purposes
• Interwell correlation using logs and other data, including advanced techniques
• The dipmeter log
• Borehole imaging logs (FMI, ATS) etc.
