  • Robust alkyl ether sulfate mixture for enhanced oil recovery
    Patent number: 11390794
    Abstract: The invention relates to a process for mineral oil production, in which an aqueous saline surfactant formulation comprising a surfactant mixture of at least one anionic surfactant of the general formula R1—O—(CH2C(CH3)HO)x—(CH2CH2O)y—SO3M and at least one anionic surfactant of the general formula R2—O—(CH2CH2O)z—SO3M and a base is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to the surfactant mixture, a concentrate comprising the surfactant mixture and a manufacturing process as well as the use of the surfactant mixture and the con- centrate in the production of mineral oil from underground mineral oil deposits.

  • ROBUST ALKYL ETHER SULFATE MIXTURE FOR ENHANCED OIL RECOVERY
    Publication number: 20200216747
    Abstract: The invention relates to a process for mineral oil production, in which an aqueous saline surfactant formulation comprising a surfactant mixture of at least one anionic surfactant of the general formula R1—O—(CH2C(CH3)HO)x, —(CH2CH2O)y—SO3M and at least one amionic surfactant of the general formula R2—O—(CH2CH2O)2—SO3M and a base is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to the surfactant mixture, a concentrate comprising the surfactant mixture and a manufacturing process as well as the use of the surfactant mixture and the con- centrate in the production of mineral oil from underground mineral oil deposits.
