摘要： This invention relates to a method of enhancing oil recovery from an underground reservoir containing oil. A gas which is miscible with oil at the temperature and pressure of injection is injected into the reservoir to displace oil. Injection is carried out in such a way as to make sure that a mixing zone is formed in the reservoir such that each fluid introduced is miscible with the fluid immediately preceding it and the fluid immediately following it. This is done by injecting small slugs of fluid miscible with, but different in composition from, the fluid adjacent to the perforated zone of the well. The injection of each slug is followed by a shut-in period to permit a mixing zone to establish itself.

摘要： A new 'cold' process for the recovery of elemental sulphur from contaminated elemental sulphur products is described. Elemental sulphur is recovered by froth flotation from: contaminated base pads of elemental sulphur blocks, stockpiles of contaminated elemental sulphur; contaminated elemental sulphur rejects from industrial handling and hauling; complex sulphur agglomerate, reject by-product from hot melting processes which is presently unprocessable and discarded (or as is otherwise referred to as 'sulphur crete melt residue'); contaminated products resulting from the exploitation processes using wells for the application of heat to reservoirs in order to recover elemental sulphur; and also from otl er sources of contaminated elemental sulphur in the oil and gas and other industries. This process comprises the steps of coarse screening, crushing, wet grinding, sizing, classifying. Then, the wet ground slurry at ambient temperature is treated by froth flotation, removing the elemental sulphur in the froth, and transporting undesirable contaminants to storage ponds or subsequent land reclamation. The initial elemental sulphur froth from the first stage of flotation is cleaned one or more times by reflotations. The cleaned elemental sulphur-bearing froth is then filtered to reinove excess water and to produce a filter cake.
