摘要： Technical system (2; 2′), method and uses for dosing of at least one liquid treatment means (12) into injection water (16) to an injection well (22), wherein the technical system (2; 2′) comprises: —an underwater line (14; 14′) for transport of the injection water (16) from a shipment site (20; 48) for the injection water (16); and —at least one liquid-tight storage unit (10) containing the at least one liquid treatment means (12). The distinctive characteristic is that the at least one storage unit (10) is structured as a volumetrically flexible unit; —wherein said storage unit (10) is placed under water (6); and —wherein said storage unit (10) is connected, in a flow-communicating manner, to the underwater line (14; 14′) for dosing of liquid treatment means (12) into the injection water (16) to the injection well (22).

摘要： The present invention is directed to a process for producing and separating oil. An aqueous fluid having an ionic content of at most 0.15 M and a total dissolved solids content of from 200 ppm to 10,000 ppm is introduced into an oil-bearing formation. Oil and water are produced from the formation subsequent to the introduction of the aqueous fluid into the formation. A demulsifier and a brine solution having a total dissolved solids content of greater than 10,000 ppm are mixed with the oil and water produced from the formation. Oil is then separated from the mixture of oil, water, demulsifier, and brine solution.

摘要： Abstract A method and device for dosing at least one water-soluble chemical (8) of a solid or semisolid form, for example in gel form, into injection water for use in an underground reservoir. Water is circulated in at least one circulation circuit (4), in which the water comes into contact with said at least one water-soluble chemical (8) of a solid or semisolid form. The water is circulated in the at least one circulation circuit (4) until the water has reached a desired concentration of the at least one chemical (8). The chemical-containing water is then dosed into the injection water.

摘要： A method of treating a hydrocarbon containing formation, comprising the following steps:
(i) drilling a first well (5), in the hydrocarbon containing formation,
(ii) introducing heating means (13) into the first well,
(iii) drilling a second and a third well in the hydrocarbon containing formation, said second and third wells being parallel to the first well,
(iv) applying heat to the hydrocarbon containing formation, and simultaneously,
(v) injecting a flooding fluid into the hydrocarbon containing formation through the second and the third well, wherein the flooding fluid is a water composition with a viscosity superior or equal to 10 mPa.s, and
(vi) extracting hydrocarbon from the hydrocarbon containing formation.
