Well logs are detailed record of the geologic formations by a borehole. These are comprehensive and important data gathered in any phase of a well’s history to identify petrophysical properties which in turn defines the economic value of a reservoir. The techniques in analysis and interpretation of well logs are therefore essential in identification of hydrocarbon recovery.

By the end of this course delegates will be able to:

• • Drive a consistent and effective Petrophysics inputs to improve oil recovery
  • Understand rock properties and pore geometry
  • Capitalize on integration reservoir and petrophysical data to maximize economic recovery of hydrocarbons
  • Attain the knowledge and practical use of total and effective porosity calculation
  • Understand new techniques and tools in well logging including imaging logging tools
  • Acquire knowledge on permeability and rock quality interpretation
  • Learn and practice integration of core analysis and open-hole logs
  • Learn from practical experiences and case studies scenarios
