  • TREATMENT FLUID AND METHOD
    Publication number: 20160102242
    Abstract: A treatment fluid made of mineral acid, viscoelastic surfactant, at least one of a fluoride source and a chelant, and optionally a corrosion inhibitor. A method of combining a mineral acid, viscoelastic surfactant, at least one of a fluoride source and a chelant, and optionally a corrosion inhibitor, in a fluid mixture. A method of contacting a low-temperature formation with a fluid mixture of mineral acid, viscoelastic surfactant, at least one of a fluoride source and a chelant, and optionally a corrosion inhibitor.
    Type: Application

  • Method for treating subterranean formation with degradable material
    Patent number: 8695708
    Abstract: A method for treating a subterranean formation penetrated by a wellbore is provided. The method includes providing a treatment fluid containing a viscoelastic surfactant having at least one degradable linkage, a hydrolysable material, and a pH control material, and injecting the treatment fluid into a subterranean formation. The pH control material may have a pH equal or greater than about 9 and may include a strongly alkaline material and an oxidizing agent.
