The course assumes no logging knowledge and seeks to establish an understanding of basic petrophysical measurements and interpretation techniques which can be applied to routine tasks, and upon which more complex and advanced information and interpretive techniques can be built.
The course strives to provide a strong and coherent foundation for the understanding of other, specialized interpretation techniques involving well log data, which are not covered here.
Upon successful completion of this course, the delegates will be able to:
ü Describe the acquisition process for both wireline and LWD measurements
ü Scan a well log to determine zones that potentially could be hydrocarbon productive, and to check for log quality
ü Convert formation and drilling fluid properties for temperature, and make other basic well log environmental corrections
ü Determine porosity using one or more logs
ü Infer lithology from the logs, and know how the logs are affected by lithologic changes
ü Understand how the Archie parameters are obtained, so that together with log data, water saturation and hydrocarbon saturation can be derived
ü Understand how pattern recognition and graphical techniques can be used to determine computation parameters as well as properties of interest
ü Understand how to judge the reservoir and completion qualities of shale gas reservoirs using basic logging techniques and more advanced measurements, as well as the value of other measurement types in an integrated interpretation
This course is intended for all geologists, engineers and technicians who work with open hole logs and who want to understand the fundamentals of what the measurements are, what affects them, and how they are used to estimate the properties of interest in the subsurface. This basic course will be useful to new personnel in the oil and gas industry as well as to more experienced professionals that want a review.
