COURSE SUMMARY

This semi-quantitative course covers all topics needed to calculate cement strength and bond index in both neat and light weight cements. You will learn how to analyze both modern and older style cement integrity logs. Numerous examples are used to illustrate CBL, VDL, CMT, CET, and USI logs. Casing and tubing inspection logs and a case history are also covered. This course is critical for completion and stimulation engineers, since a successful frac job is impossible in bad cement.

WHO SHOULD TAKE THIS C0URSE

Petrophysicists, log analysts, geologists, reservoir engineers, completion engineers, stimulation engineers, and university / tech school students who wish to broaden their skills in more advanced uses of well logs.

BENEFITS

  • Provides understanding of cement strength and bond log response
  • Provides understanding of CBL tool theory and practice
  • Provides "computer ready" mathematics
  • Gives insight into log quality problems that affect cement analysis
  • Permanent reference material

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.
