Course Description:

Basic principles of physics are developed to explain the functioning of modern logging tools. Wherever possible, the physics of logging measurements is related to everyday tools and appliances. Participants develop an appreciation for the constraints and limitations of operating in the borehole environment. A number of actual log examples are related to basic principles in the description of reservoir properties such as porosity, mineralogy, formation factor, saturation, and hydrocarbon type, for essentially clean reservoirs. Cross-plotting and reconnaissance techniques, the eyes of the part-time log interpreter, discriminate between water, oil, and gas, quickly and efficiently. Participants gain realistic experience by working in teams on a comprehensive log interpretation exercise.

Course Goal:

To enhance the participants’ knowledge, skills, and attitudes necessary to develop an appreciation for the constraints and limitations of operating in the borehole environment
