Course Description

This short course introduces fundamental log quality control concepts for all open hole logs usually run in wells. The participants will learn how to effectively control the quality of all logs in real time. The exercises are developed with actual logs ran in real wells, so the participants will be exposed to log quality control on real data. At the end of the course the participants will be trained to perform log quality control on real time at wellsite as well as post-morten in the office. Furthermore, this course establishes some general guidelines for conducting logging operations, reviewing tool calibrations, monitoring survey progress, calculating shale volume, porosity, water saturation, and permeability from older open and cased hole well logs. Integration and calibration to modern tests, and production data will a stressed. 

Course Objectives

  • Understanding what older logs really measured
  • Understanding the rock/fluid model for log analysis
  • Providing "computer ready" mathematics
  • Gaining insight into rock quality versus well performance
  • Answering oriented results, with quality control guidelines
  • Defining basic survey parameters, establishig log scales,
  • Understanding how to monitor tool responses
  • Understanding how to confirm the validity of the data acquired from commonly used logging devices.

Who Should Attend?

  • Geologists
  • Geophysicists
  • Petroleum Engineers
  • Petrophysicists
  • Technicians/ Managers, if they are exposed to (or use) well-hole logs in their daily work.
