Course description

Different methods are expanded to include deterministic and probabilistic evaluations. 
LWD and MWD concepts are discussed and compared to wireline logs, Quality assurance of data and interpretations are emphasized throughout the week.  Physics of the measurements along with practical discussion of the theory will allow each participant to follow simple procedures for the rapid and accurate interpretation of logs
To accomplish the learning objectives, which are set for each day, attendees are given hands-on problems and exercises with field examples to reinforce the course instruction.


This course is suitable for all engineers and technicians dealing with open hole well log data. This would apply to engineers in the various disciplines in the oil companies. Engineers from drilling, reservoir, geology, production, geophysics and Petrophysics departments will benefit from this course. Moreover, engineers and technicians dealing with log processing, log interpretations, data processing and IT engineers dealing with data management and databases will find this course of special benefit.
