Fundamentals of Quick-Look Log Analysis


Anyone who needs to grasp the essential features of petrophysical data and how to use it quickly and effectively, qualitatively and quantitatively, to reveal the commercial significance of a well.


- Rocks: Sedimentological controls on grain size, sorting, clay content, mineralogy and the trends that can be observed in sedimentary sequences
- Rock and Fluid Properties and Interactions: Fundamentals of petrophysical rock properties including: porosity, permeability, relative permeability, wettability, capillary pressure, cation exchange capacity, fluid saturations
- Drilling and Logging Process: Understanding the nature of the borehole and how the logging tools are run in order to understand the limitations and uncertainties in the log data
- Review of Conventional Logging Tool Theory: Each tool is measuring a different rock property (e.g. neutron density, electron density, gamma-ray abundance), which in turn is transformed to another property (e.g. porosity, bulk density, lithology)
- Quick-Look Log Analysis Workflow: All of the above will be used to undertake quick-look analysis of several log suites. The methods will include: data quality control, lithology assessment (including Vshale), porosity estimation, fluid saturation estimation (hydrocarbon indicators), permeability indicators, and reservoir summation and integration with mud logging data
