The invention relates to a method for use in sampling and/or flow measuring, quantity gauging, possibly other analysis, in reservoir fluid that one comes across in a ground formation (1), e.g. during drilling of an exploration well (3) for hydrocarbons. Inter alia, an object of the invention is that the sampling, flow measuring and quantity gauging or the remaining analyses shall be carried out in reservoir fluid positioned down into the hydorcarbon carrying layer (2), the same being maximum stabilized and with a content of drill fluid not worth mentioning after the drilling. This is realized in such a way that the well (3) is sealed in an area at the hydrocarbon carrying layer (2) by means of seals (5, 6); that reservoir fluid from said layer (2) is supplied in a drill string (4) used during drilling and passed through the sealed area of the well (3); that the sampling an the respective measurements or analyses are carried out within the sealed area of the well (3) while the reservoir fluid flows controllably into the drill string (4), and that reservoir fluid is returned from the drill string (4) to the hydrocarbon carrying layer (2) after completed sampling and respective measuring or analysis. The sampling and the respective measurements and analysis are made by means of accessories (9, 10, 11, 12) disposed in a housing member (7) on the drill string (4).
