Course Aim
After completing the course participants should be able to:
• suggest geophysical methods for solving exploration and environmental related problems
• describe limitations for the geophysical methods
• explain qualitatively Solid Earth Physics, physical fields, composition and structure of the Earth
• explain basic interpretation principles, including here the principles for choosing of principal/conceptual model when interpreting geophysical data, ambiguity, relation between data uncertainty and uncertainty on model parameters, application of petrophysical measurements and other a priori information
• explain and apply the concepts of convolution, Fourier transformation and filtering and provide examples for use in geophysics
• explain the significance of data sampling density and the concept of aliasing
• describe basic principles (physics, measurement techniques and interpretation) for the geophysical methods treated in the course. 

Contents
Continuous and discrete data: Sampling; spectra; Fourier transformation and filtering.
The magnetic field of the Earth – magnetometry: The Earth magnetic field. Magnetic properties of rocks and unconsolidated sediments. Measuring techniques and data processing. Exploration for mineral resources.
The gravity field of the Earth – gravimetry: Geodesy with emphasis on the gravity field of the Earth. Density of rocks and unconsolidated sediments. Corrections to gravity data and the calculation of Bouguer anomalies. Regional/residual anomaly separation. Gravity method in exploration.
Electric and electromagnetic methods:  Electric conductivity of rocks and unconsolidated sediments. Dielectric constants of rocks and unconsolidated sediments.  Electric methods based on natural and artificial currents. Electrical sounding and mapping.  Examples in mineral exploration, environmental studies, prospecting for and planning of water resources, pollution of ground water. Electromagnetic fields. Depth of penetration. Electromagnetic methods with examples of application in mineral exploration and environmental studies.
Ground Penetrating Radar and borehole radar with examples in environmental studies.
Magnetic resonance sounding.
Radiometric method: Measuring of gamma radiation and applications.
Borehole methods and logging: acoustic/sonic log; calliper log; density log; gamma log, induction/conductivity log, neutron log, resistivity log, SP-log (self-potential); temperature log; IP log (induced polarization) and magnetic log. Examples from logging in hard rock and sediments. 

Realization
Each course occasion´s language and form is stated and appear on the course page on Luleå University of Technology's website.
The teaching will be as lectures and one compulsory laboratory training on petrophysical parameter estimation. Lectures are complemented by computer exercises performed in dedicated lecture rooms with computers and software. The lectures are focused on basic theory and applications.

Examination
If there is a decision on special educational support, in accordance with the Guideline Student's rights and obligations at Luleå University of Technology, an adapted or alternative form of examination can be provided.
Petrophysical laboratory work with written report.
Written examination with differentiated grades (G U 3 4 5) will be arranged at the end of the teaching period. The examination will include theory as well as problem solving.
Petrophysical laboratory work with written report is graded (G U).
