dc.description.abstract | The problem that a magnetic drilling mud cause to the accuracy of the directional drilling technology is
outlined. The purpose of the work is identified in the theoretical modelling of the magnetic response of the
magnetic mud, a fluid that is contaminated with small amounts of magnetic materials. The theory of mixing
magnetic materials is reviewed, practical results are derived in detail and discussed. The classic model of an
ellipsoid, instrumental for the calculations, is presented in detail. Are then defined and developed the models
for suspended particles under the combined effect of a magnetic field and Brownian motion; the predictions
are compared to the available experimental data. | nb_NO |
