An apparatus for controlling the injection pressure of an aqueous polymeric solution in an oil well is formed by: at least one pressure modulation valve, allowing, per valve, a maximum pressure loss of 5 bars practically without any mechanical deterioration, the one or more valves being connected in line with; a tube containing vortex modules, each creating a maximum pressure loss of 5 bars, practically without any mechanical deterioration, a vortex module being a section of tube, which is closed at one of its ends by a cap perforated with a hole, and which can be inserted into the detachable tube. The purpose of the apparatus is the ability to reduce the pressure to 100 bars with total mechanical deterioration of less than 10%. A method for using the apparatus is also contemplated.

Method for treating mineral sludge by flocculation in-line then above ground

A method for loading the hold of an ore carrier with loose ore, according to which the hold is loaded, consecutively, with a portion of the ore treated with a superabsorbent polymer and a portion of the ore not treated with a superabsorbent polymer.

Method for loading loose iron ore partially treated by means of superabsorbents

A method for enhanced oil recovery in an oil-bearing formation having high permeability zones, constituting preferential passages for the injected liquid, involves blocking the preferential passages by injecting into the formation an aqueous solution based on water soluble polymers at a concentration such that the viscosity of the aqueous solution is higher than the viscosity of the oil. Once the blocking step is completed, an aqueous solution is injected having an identical composition to that used in the blocking step, but at a lower polymer concentration.

Enhanced oil recovery by polymer without supplementary equipment or product

Installation for enhanced oil recovery comprising in succession: a polymer storage hopper, a grinding device and a pressurized injection pump. The grinding device has a chamber for grinding and draining the dispersed polymer comprising a rotor and a stator, and on all or part of the periphery of the chamber, a ring fed by a secondary water circuit. The ring communicates with the chamber for spraying of pressurised water on the blades of the stator. A method implementing the installation is also provided.
