SUMMARY T he separation 0% Írude, Oit and Gas in several stages is of parlicular interest in those f ields where oil reaches the well-head at high pressure; Dy appl .ying llie first stage local& a t the well, a reduction o[ pipeline diameters becomes possible. The gas from the first stages is dry enough no1 to justify stripping, and contains relatively ililtle sulphuretted hydroqen: liiat of the intei.mediate stages requires no recompression before stripying, and finally the gas is usually drier und of much reduced volume while the ldss 0% iiolaiile products is reduced.
T he optimum condiiions for separation of the two componenls - parlicularly the numbeT of steps to be used and the pressures lo be adopted - a re considered and discussed fully from points os view both theoretical and practical.
