Abstract

The invention relates to a method of injecting water and gas, possibly just water, into a petroleum-carrying stratum (2) of a subsoil formation (1), whereby the water and the gas, possibly just the water, are/is injected by means of an injection well (4) formed in the subsoil formation (1). The object of the invention is to avoid that water which is to be injected, will require treatment by, among other things, the addition of chemicals inhibiting formation of hydrate from the gas, biological activity in the formation (1), precipitation of salts and minerals from the water, corrosion of equipment etc. This is realised by the water to be injected, being taken from aquifers (3) in the subsoil formation (1) and carried directly into the injection well (4) through at least one opening (5) which is formed in the wall of the well by said aquifers (3). Then the water is fed from said opening (5) to the point in the injection well (4) where the water and the gas, possibly just the water, are/is to be injected into said petroleum-carrying stratum (2). The injection well (4) comprises necessary pumping equipment to be used during the injection.
