Abstract
A method for improving fuel collection from an underground deposit comprising stimulating fuel-containing sections of an underground formation, the sections being located between a first well and a second well, the first well being either an injection well or a production well, and the second well being a production well. The method includes arranging a mechanical wave generation device downhole in the first well and arranging at least a first mechanical wave sensor in the production well, injecting a pressurized fluid into the formation from at least the first well, activating the mechanical wave generation device downhole to project mechanical waves into and through the fuel-containing sections, receiving and processing the waves sent from the first well, generating a tomography of the underground environment between the first well and the second well, and collecting fuel in the second well via inflow valves arranged in the second well.
