Petrophysics - Well Logging, Fundamentals
About
About the course
Course content
Fundamental petrophysical concepts and equations. The most important classical well logging methods: Measurements of resistivity, natural gamma ray, neutron porosity, density, average atomic number parameter, Pe, acoustic parameters, measurements of formation pressure. Discussions of the measurement environment and geometrical conditions in a borehole. Environmental corrections. Nuclear magnetic resonance, NMR. Dielectric properties. Connections between the measured parameters and the rock's porosity, permeability, fluid/gas saturation, lithology (rock types) and clay content. Use of core data. In the exercises emphasis is put on practical interpretation of log data.
Learning outcome
Ingress:
The course gives insights into the role of borehole measurements in search for hydorcarbon reservoirs. The course teaches the students to understand classical measurement methods and to use these to find important rock parameters like porosity, permeability, water saturation and the rock types in the borehole.
Knowledge:
The students learn to understand and to use the following:
- Fundamental petrophysical concepts and equations. How does the construction of the rock influence the measurements we do and important petrophysical parameters lik porosity, permeability and saturation.
- The most important classical log measurements used in boreholes: Resistivity, natural gamma radiation, neutron porosity, density, photoelectric absorbtion index, Pe, acoustic measturements, formation pressures, magnetic resonance and more.
- The measurement environment in a borehole and environmental corrections of the data.
- Find how the measured parameters can help us to find the porosity, permeability and water/hydrocarbon saturation, shale content and rock type.
Skills:
- The students are expected to understand and to do a simpel interpretation of the more common log measurements that are done in a borehole. They should be able to find the main lithologies and estimates of porosity , saturation and permeability and what fluid types - water, oil and gas are present in the formations.
General competence:
- During group work the students learn to cooperate and to take responsibility for their part of the assignments given.
- By working with real data from the field, they learn to understand that real data can be uncertain and that one has to use common sense and understanding in order to find good answers to the interpretation problems.
