  • Methodology for determining curves of productivity of wells for exploiting underground gas storage and underground natural reservoir of compressible fluids
    Patent number: 10262085
    Abstract: The invention relates to a characterization method for characterizing the performance of wells in a stockpile or deposit of compressible fluid, the method comprising the steps of: obtaining a plurality of operating points (400); defining a family of operating models (IPa, IPb); for each model of a family, enumerating (410) those points of the plurality of points that are reproduced by said model; and for managing said stockpile or deposit, selecting (420) at least one model (M) from the family of models on the basis of at least the result of the enumeration step.

  • 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.
