  • Water shut-off method for porous formations
    Patent number: 10351756
    Abstract: Organoclay is used as an alternative emulsifier and reinforcing agent to enhance the strength of emulsified polymeric gel aqueous solutions and form water in oil emulsions. The stability of the emulsion can be controlled by controlling salinity and the intensity of initial mixing. The new system can be used for water shut-off treatments as well as a relative permeability modifier in high water permeability zones. In addition, the system can tolerate salts much better than classical surfactants. This system will be appropriate for wellbores having high temperature (>85° C.) with harsh environmental conditions.
    Type: Grant
    Filed: March 12, 2018
    Date of Patent: July 16, 2019
    Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and Technology
    Inventors: Ibnelwaleed Ali Hussein, Ahmad Akanbi Adewunmi, Abdullah Saad Sultan, Khalid Saad Elkarsani, Ghaithan A. Al-Muntasheri
