    Abstract: A device for dosed release of a fluid from a source (4) for this fluid to a receiver (12) via a pipe (8). The device comprises an influencing device (2) for influencing the release of the fluid from the source (4), and a control device (30) for control of the influencing device. According to the invention the device comprises a fluid accumulator (20) which communicates with the pipe (8) at a location (16) between the influencing device (2) and the receiver (12). The influencing device (2) is an electrically operated shut-off valve which is arranged to be opened by means of impulses from the control device (30) when the pressure of the fluid in the accumulator (20) has reached a minimum value (P1min), and to be closed when this pressure has reached a maximum value (P1max). When the shut-off valve (2) has been closed and the accumulator (20) has been filled, the accumulator (20) effects release of the fluid to the receiver (12).

    Abstract: An oil field production chemical, especially a scale inhibitor, is in the form of particles thereof carrying a coating e.g. of a dispersing agent. The coating may be polymeric such as an oligomeric polyacid polyester, a polymeric alkoxylated alcohol or a fatty acid polyamine condensate or it may also be a surfactant and may be used in the form of a suspension in an inert oil, such as diesel oil or kerosene which may be injected into a subterranean formation to inhibit the formation of deposits, e.g. scale in oil wells over a longer period than compounds free of the coating.

    Abstract: NORMs are inhibited or prevented from precipitating with scale produced by a hot aqueous solution by adding multiple portions of a crystal structure modifier to the aqueous solution as it cools before and during removal of silicon containing components by precipitation. Preferred crystal structure modifiers include polyacrylate crystal structure modifiers and phosphonomethylated amines.
