  • Method and system for mixing liquid and gas that have been separately injected into a well comprising two coaxial cylinders and discharging the liquid/gas mixture into an underground formation
    Patent number: 11401791
    Abstract: A method and system enable injection of gas into an underground formation, enhanced by the simultaneous injection of liquid. Mixing of the gas and the liquid that have been separately injected into a well comprising two coaxial cylinders can occur at different levels in the well in order to facilitate the flow and to limit the gas pressure necessary for reinjection at the wellhead. Thus, the system and the method require less energy and the associated gas compression equipment is less expensive. The method and system can be applied to geothermal energy applications, underground gas storage, notably CO2, or to enhanced recovery in petroleum reservoirs.

  • Method of in situ repair of a wellhead base flange
    Patent number: 9169708
    Abstract: An in situ method for repairing a base flange of a wellhead. At least one layer of a polymerizable composite material is applied to a damaged surface, an elastic seal is placed on the layer of composite material, and a reinforcing collar is pressed against the seal on the surface of the flange covered with the composite material. An arrangement of an in situ repair of a base flange of a wellhead includes at least one layer of a polymerized composite material on a damaged surface, an elastic seal on the composite material, and a reinforcing collar pressing the seal against the damaged surface.
