COURSE SUMMARY

This quantitative course continues coverage of basic petrophysical analysis by presenting the case history for Exercise 1, which you wrapped up in the previous Lecture. Here you will learn how closely your answers match ground truth, namely core porosity and permeability, and initial production rate. You can revise your analysis to obtain a better match by adjusting parameters or log picks, but don't expect perfection. Two different core analyses on the same core demonstrate that lab data is not always perfect either. Treat all data as having reasonable possible error.

WHO SHOULD TAKE THIS C0URSE

Managers, geologists, log analysts, geophysicists, reservoir engineers, completion engineers, stimulation engineers, and university / tech school students who wish to become proficient in petrophysical analysis or who need to manage or make use of petrophysical results will benefit from this course.

BENEFITS

  • Provides understanding of the need to compare analysis results to ground truth
  • Provides step-by-step procedures for checking your work
  • Provides worked example for further study

LECTURE CONTENTS

  • Case History - Exercise 1
  • Review Results for Exercise #1
  • Compare Results to Ground Truth
  • Integrate Logs, Cores, and Production History
  • Revise Log Analysis Picks and Parameters to Match Ground Truth - Calibration

ESTIMATED TIME : 1hr

Ross Crain
Ross Crain

Mr Crain is a Professional Engineer with over 35 years of experience in reservoir description, petrophysical analysis, and management. He has been a specialist in the integration of well log analysis and petrophysics with geophysical, geological, engineering, and simulation phases of oil and gas exploration and exploitation, with widespread Canadian and Overseas experience. He has an Engineering degree from McGill University in Montreal and is a registered engineer in Alberta.

He wrote “The Log Analysis Handbook”, and he offers seminars, mentoring, or petrophysical consulting to oil companies, government agencies, and to consulting service companies around the world. Projects have spanned conventional and unconventional reservoirs in more than 40 countries.

Ross is credited with the invention of the first desktop log analysis system (LOG/MATE) in 1976, 5 years before IBM invented the PC. He continues to advise and train people on software design, implementation, and training. For his consulting practice, he uses his own proprietary software (META/LOG), and is familiar with most commercial systems.

He has won Best Paper Awards from CWLS and CSEG and has authored more than 30 technical papers. Mr Crain was installed as an Honorary Member of the Canadian Well Logging Society for his contributions to the science of well log analysis.

Ross's current interest is development of practical solutions for petrophysical analysis of all forms of unconventional reservoirs, determination of accurate mechanical properties of rocks for stimulation design, mentoring of both novices and experienced petrophysicists.
