A fluid is directed under pressure via an injection nozzle/jet (3) from a pipe (1) into a surrounding area and infused into a layer (2) of rock or earth containing crude oil. A direction of emission, preferably an angle between the main axis of the pipe and the direction of emission, is changed preferably step by step at intervals. Nitrogen or carbon dioxide is used as a liquid gas. An independent claim is also included for a device for forcing a fluid into a layer of rock or layer of earth by using a suitable pipe.
