Definitions

  • the invention relates to a method of injecting water and gas, possibly just water, into the petroleum-carrying strata of a subsoil formation.
  • the main object of the present invention is to provide a method of injecting water and gas, possibly just water, whereby is avoided that the water to be injected has to pass said costly treatment.
  • This is achieved by the injection water being recovered from aquifers present in the subsoil formation.
  • the water recovered from the subsoil formation is fed directly into the injection well through at least one opening formed in the wall of the well by said aquifer.
  • the water is fed from said opening to the point in the injection well where the water and the gas, possibly just the water, are/is to be injected into the petroleum-carrying strata.
  • use is made of water from a source of higher temperature and pressure than what has been common with water supplied from the surface.
  • FIG. 1 shows a simplified vertical view of an injection well for the injection of water and/or gas
  • FIG. 2 shows a schematic vertical sectional view of an injection well with pump and injection pipe for water and gas.
  • the present method relates to injection of water and gas, possibly just water, into a subsoil formation 1 carrying petroleum.
  • the injection may take place by water and gas being injected simultaneously or alternately, or maybe by just water being injected into the subsoil formation 1 .
  • the injection of water and gas, possibly just water is realised by means of an injection well 4 which is formed in the subsoil formation 1 and extends at least down into a petroleum-carrying stratum 2 thereof.
  • the injection well 4 is preferably formed with a wellhead, and the wellhead comprises, among other things, necessary equipment for supplying the gas to be injected into said petroleum-carrying stratum 2 .
  • the water to be injected is recovered from an aquifer 3 of the subsoil formation 1 , and the water is fed directly into the injection well 4 through at least one opening 5 formed in the wall of the well by said aquifer 3 .
  • the water is then fed 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 without having been taken to the surface. This may happen, for example by the water being pumped from the opening 5 to the location in the injection well 4 where the water and the gas, possibly just the water, are/is to be injected.
  • a pump 7 is preferably placed close to the opening 5 in the injection well 4 .
  • the opening 5 may, for example, be formed by perforation of the wall of the well and there could also be arranged a sand filter in connection with the opening 5 .
  • the injection well 4 also comprises an injection pipe 6 for gas.
  • the injection pipe 6 is passed from the well-head, where the gas is added, and down into the petroleum-carrying stratum 2 where the water and gas, possibly just the water, are/is to be injected.
  • an upper packer 8 and a lower packer 9 isolating the aquifer 3 from the surface, or other strata of the formation 1 such as the petroleum-carrying stratum 2 .
  • a pump 7 which is positioned in the space between the packers 8 , 9 , pumps the water into the injection pipe 6 and further out into the petroleum-carrying stratum 2 .
  • the pump 7 may be placed in a pipe socket which is formed on the injection pipe 6 , and may be operated electrically or hydraulically.
  • At least one check valve 10 is positioned in the injection pipe 6 above the pump 7 .
  • At least one additional check valve 11 is positioned at the outlet of the pump 7 into the injection pipe 6 .
