Útdráttur: The standard operation procedures for sampling and analysis of two-phase wells used during the well discharge test and during the regular production stage are very similar. A portable Weber-type separator is attached to the well head allowing to collect liquid and steam phase separately. The analytical results of both phases (so called discharge data) are recalculated to the chemical composition of the deep fluid using geochemical computer codes with appropriate thermodynamic database. Proper sampling and analysis of well fluids is the first step in long term process of understanding the system and predicting its response to the production. Therefore, care has to be taken when choosing sampling container types (glass or plastic, amber or transparent), pre-treatment and preservation methods (dilution, filtering, addition of chemicals), and analytical techniques. These have to be adjusted to the physicochemical conditions of the sampled fluids since the interpretation of the results is confined by the quality of the data.
