Introduction to Log Analysis

Course Overview
This three-day course covers the fundamentals of log analysis for understanding openhole logs and teaches immediate practical skills in formation evaluation. Hydrocarbon evaluation, porosity and permeability estimation are covered, together with rock typing and pay assessment. Methods to integrate core data, drill cuttings reports, DST results, and production information with logs are described. Log quality control and normalization issues are also discussed. Participants are required to bring calculator or a laptop computer for all 3 course days - please be sure to fully charge laptop batteries prior to each day. Excel freeware log analysis software is provided.

A complete set of course materials and lunches are included.

Larry Maple graduated in 1972 with a B.A. Geology degree and joined the petroleum industry as an exploration and development geologist in 1975 and has focused on petrophysics since 1978. He has held a variety of international E&P petrophysical and management positions while resident in Singapore, Oklahoma, and Texas. Over the course of these assignments, he has worked a wide variety of geological formation types, ranging from shaly sands and tight gas sands to carbonates and evaporites. Larry is currently an independent consultant/trainer.

This was a great course that taught me the fundamentals of log analysis. There is a lot of useful information that I can use right away. I wish I'd taken this course sooner! Looking forward to taking more courses that will add upon this knowledge that I learned here.

Detailed and thorough course. I went from a zero on log analysis to functional. Larry Maple is a knowledgeable and clear instructor.

I attended this course wanting to learn how to read and mark up a set of logs. This course instead provided me with a new skill set that is very practical to my job.

Overall I enjoyed this course. It covered a lot of material and gave lots of examples. The spreadsheets with built in equations are neat to have.

This was an all-encompassing course. There was good variety of modern Canadian and US play type examples.

This course does a great job at going through all the mathematical theory with log analysis and a little bit on how the tools work. Even though there were a few Canadian logs in the course, lots of examples and course content was from the USA. The theory is still the same but it would be nice to see a Cardium, Montney, Duvernay, Bakken, Dunvegan log case study done in class. Almost all class exercises involved getting a .las file, copying pasting in to excel and generating plots for bulk water volume, porosity, Sw etc. Not a whole lot on examining logs qualitatively and discussing or looking at interesting case studies. I was hoping at the end there would be a bit more "tying it all together" as you look at each log individually and the calcs associated with it then move on to the next tool. The instructor was fantastic. Really helpful with questions and extremely knowledgeable gentleman.
