Course Description
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 joined the petroleum industry in 1975, and worked initially as an exploration and development geologist at various locations in Oklahoma and Colorado. In 1978 he began working in petrophysics, transferred to Singapore, and worked as the Southeast Asia regional petrophysicist for Phillips Petroleum Company. In that position he was responsible for petrophysical evaluations of Phillips's exploration and development activities in Australia, China, Indonesia, Malaysia, Thailand, and the Philippines. He subsequently spent most of his career in a variety of technical divisions working on Phillips's and then ConocoPhillips' international E&P projects while based in Houston or Oklahoma with occasional long term assignments to places such as Norway and Qatar. In the course of these projects he has worked a wide variety of geological formation types, ranging from shaly sands and tight gas sands to carbonates and evaporites. Larry also began teaching petrophysical training courses in 1978 and became one of the primary lecturers for internal courses in petrophysics, both domestically and internationally. In 1983, he took on the primary responsibility for developing internal training manuals, materials, and lecture presentations and coordinating new-hire training sessions for petrophysics. At various times in the following thirty-five years he has taken post graduate courses in sedimentary geology, geophysics, and reservoir engineering, but his best education has always come through project work.

Overall, the course provided me a better understanding of Log Analysis. From its derivation to its technical use, it is a great skill to learn. Its a great course for anyone who is interested in Log Analysis.

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.

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.

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

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.

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.
