Wireline Log Interpretation

Audience

The course has been designed to enable the explorationist, development and production geologist to evaluate and integrate wireline log data.

Content

This course provides a basic understanding in the following elements:

  • The logging environment, introduction to the borehole.
  • Conventional wireline logs: Caliper, Tension, Gamma ray, Spectral Gamma ray, Spontaneous potential, Resistivity, Density, Neutron porosity, PEF, Sonic 
  • Data QA and depth matching 
  • 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.

Learning Objectives

  • Understand tool theory, uses and limitations
  • Interpret lithologies and reservoir characteristics
  • Identify depositional sequences and correlate wells
  • Determine porosity, saturation and reservoir fluid type
  • Employ quicklook methods of formation evaluation
