摘要： A method and system for water injection into an oil and/or gas containing subterranean formation is shown, the method comprising: arranging a submerged water filtration station with a pump feeding inlet seawater through at least one filtering membrane to a water injection pump, subjecting the water to ionizing irradiation at a location between the seawater inlet and the water injection pump, whereby at said location the water is guided past a submerged radiation source which is distributed for penetration of the body of injection water.

摘要： A system and a method for seawater pre-treatment and injection are disclosed. The seawater pre-treatment and injection system comprises at least one subsea water well connectable to a seawater injection system comprising at least a water injection pump in flow communication with a water injection well, wherein the subsea water well is made as a hole into a groundwater holding strata under the mud-line with a water permeable or non-permeable completion using the seafloor soil for filtration, with an inner tubing connectable to the seawater injection system via a valve.
