ABSTRACT:
In producing CO.sub.2 from subterranean reservoirs at conditions apt to cause two-phase flow in pipes conveying the fluid, the formation of hydrates is prevented by adding a polyhydric alcohol hydrate inhibitor in proportions capable of maintaining an effective concentration within the aqueous liquid-phase in spite of partitioning of the inhibitor into a CO.sub.2 -rich liquid-phase of many times greater volume.
