Geolog - Multi-Mineral Analysis and Interpretation Using Geolog Multimin

Objectives:

This course is designed, with a hands-on, practical approach, to assist in learning how to perform sophisticated formation evaluation using Multimin, the advanced petrophysics application of the Emerson™ Geolog system. The course is taught by professional trainers to small groups of interested people from the petroleum industry. The material is presented by following examples on a workstation.

The student is guided through the following examples:

• First example - a documented example of a simple analysis, and then further interpretation of the example
• Complex example
• Silt example
• NIMBLE example
• Carbonate example

Duration:
2 days

Prerequisites:
To gain the most from this training course, the following prerequisites are required:

• A working knowledge of the Geolog system and its conventions, the methods to import data into the software, and the way data is stored.
• A working knowledge of the methods used in Geolog to perform basic preparation tasks for petrophysical data including:
  • depth-matching, editing and despiking for petrophysical logs
  • environmental corrections
  • data displays
  • crossplotting
• A general understanding of petrophysics, including the concept of response equations for tools, and the methods used to calculate shale volumes, porosities and water saturations. An appreciation of cation-exchange based methods for water saturation determination would be beneficial, as would an understanding of mineralogy effects on tool responses.

Who Should attend:
Petroleum geologists, engineers, and petrophysicists
