  • Gemini surfactants containing an unsaturated linker for clay swelling inhibition
    Patent number: 11566167
    Abstract: Amidoamine-based gemini surfactants having dual chains connected via an alkenylene or alkynylene linker. Each chain contains a quaternary ammonium head group and an ethoxylated alkyl tail. A water-based drilling fluid containing the gemini surfactant is also provided. As examined by linear swelling and free swelling tests, the gemini surfactant is effective in reducing clay swelling.
    Type: Grant
    Filed: December 18, 2019
    Date of Patent: January 31, 2023
    Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS
    Inventors: Muhammad Shahzad Kamal, S. M. Shakil Hussain, Mobeen Murtaza, Mohamed Mahmoud
  • Methods for clay swelling inhibition using gemini surfactants containing a saturated linker
    Patent number: 11447688
    Abstract: Methods of controlling clay swelling and stabilizing subterranean geological formations containing swellable clays (e.g., montmorillonite, bentonite) are described. The methods involve treating the swellable clays with a composition containing an amidoamine-based gemini surfactant. The gemini surfactant has dual chains connected via an alkylene linker, whereby each chain contains a quaternary ammonium head group and an ethoxylated alkyl tail. As examined by linear swelling and free swelling tests, use of the gemini surfactant is effective in reducing swelling of the clays.
