Time you enjoy wasting is not wasted

E. R. (Ross) Crain, PEng began his early career in well logging, moving to seismic processing, reservoir engineering, project management, and petriohysical software development, which led to his lifelong advocacy for the concept of Integrated Petrophysics, leading to the publication of "Crain’s Petrophysical Handbook" in 1999, an on-line textbook for trqining geoscientists and engineers the value of Integrated Petrophysics.

In 2019, Ross was awarded the first  CWLS Lifetime Achievement Award for his contributions to the CWLS and the geoscience community over the course of his 55+ year career. He is a Past President and Honourary Member of CWLS.

His consulting practice included projects in 45 countries, as well as course preaentations to 3000 students. Ross has retired from active consulting and lives in Calgary, Alberta, Canada.

E. R. (Ross) Crain, PEng is the publisher and author of "Crain's Petrophysical Handbook", an Internet-based eLearning Resource, the first and only complete on-line textbook for Integrated Petrophysics

In March 2019, Mr. Crain was awarded the first ever CWLS Lifetime Achievement Award
for his "willingness to openly share and educate", acknowledging his 38 years of course presentations and the 20th Anniversary of his petrophysical training website.

Ross is a retired Consulting Petrophysicist and Professional Engineer living in Calgary, Alberta, Canada. In a career that spans nearly 60  years, he specialized in integrated petrophysical analysis, bringing to the task a background in well logging operations,  geophysical data processing, reservoir engineering, cash flow analysis, software development, project management, and entrepreneurship. As an independent consultant, Ross has worked on projects in 45 countries on 6 continents and several oceans.

Ross is a Life Member of Association of Professional Engineers and GeoScientists of Alberta (APEGA) and was elected an Honourary Member of the Canadian Well Logging Society (CWLS) in 1994 for his contributions to the CWLS and to the petrophysical community.

Ross taught more tham 3000 students basic and advanced petrophysics in open sessions and in-house courses and is the author of more than 100 articles and technical papers. He was awarded Best Paper of the Year from CSEG (1981) and CWLS (1985). He published "The Log Analysis Handbook", a 700 page hardcover textbook in 1986, and its electronic Internet cousin "Crain's Petrophysical Handbook" in 1999.

Ross's current interest is mentoring of novice and experienced petrophysicists, geologists, and engineers, making use of an extensive library of eBook reference manuals, narrated self-study slideshows, and video courses.

In a parallel career, Ross created a purebred Horned Hereford ranch from the bush in west-central Alberta, receiving his 25 year pin from the Canadian Hereford Association in 2005. The ranch was Green from day-one with wind power for the first 20 years and solar thereafter - it is still off-the-grid today.

Ross's hobbies included building large-scale model railways, traveling on antique trains, and walking with his Great Pyrenees dogs. Today he is content with his music, audio books, and old-time radio collections, and walking the hills near the condo in Calgary.
