<p>A method, system and means of generating electricity from fluid flow 2 from at least one subterranean first zone 1 containing fluid and connected via a flowpath to a second zone 15. The flowpath can include pipes, casings or conduits 3, 5, 2 and 14. At least one turbine 6 is in the flow path(s). Each turbine 6 has an inlet connected directly or indirectly to the first zone and an outlet connected directly or indirectly to the second zone. Pressure difference between the inlet and the outlet of each turbine provides a flow of the fluid from the respective inlet to the respective outlet to drive the turbine(s). At least one electricity generator 7 is integrated into or operatively connected to the turbine(s). Multiple turbines (Figs 3 and 4) can be in series and/or parallel in the flowpath(s). The first and/or second zones can be subterranean formations, such as depleted or disused oil or gas reservoirs.</p> |
