  • Patent number: 9150778
    Abstract: A method for improving flow conditions in a porous media while servicing a well penetrating to the porous media includes: stopping drilling or production activities on the well; introducing a well control fluid into the well and the porous media, the well control fluid comprising a mixture of a surfactant, a co-surfactant and a carrier fluid; holding the well control fluid in the well and the porous media in the presence of water while the well is being serviced, such that the fluid penetrates the porous media and forms a water film on surfaces of the porous media; and when well servicing is finished, resuming drilling or production activities on the well.
    Type: Grant
    Filed: June 21, 2012
    Date of Patent: October 6, 2015
    Assignee: Intevep, S.A.
    Inventors: Pablo Manrique, Franklin Archer, Maria Gracia Araujo, Deivis Suarez
  • Patent number: 9109443
    Abstract: A combined injection and production method includes establishing a production well and an injection well into a hydrocarbon-bearing formation; introducing a mixture of a surfactant, a co-surfactant and a carrier fluid into each of the production well and the injection well so that the mixture flows into porous media surrounding the production well and the injection well; holding the mixture in the porous media surrounding the production well in the presence of water for a period of time sufficient to form a water film on surfaces of the porous media surrounding the production well; and injecting an injection fluid into the injection well while producing from the production well, whereby hydrocarbons flow from the porous media around the injection well toward the production well.
